A1 - Simon, Franz-Georg A1 - Biermann, Vera T1 - Sustainable environmental protection N2 - Permeable reactive barriers (PRBs) offer an alternative as opposed to more cost-intensive active methods for groundwater remediation, e.g. pump-and-treat. Long-term performance of PRBs, however, is crucial for the technology’s success. The paper summarises the results of long-term column experiments with elemental iron (Fe0) and hydroxyapatite (HAP) as reactive materials for the removal of uranium from groundwater. Good removal results have been achieved using elemental iron with possible reaction paths being reductive precipitation and adsorption on to corrosion products of Fe0.

Approximately 70% of the demolition waste is currently recycled. Most recycling applications, for example in roadbed substructures, can be seen as a kind of downcycling. However, there are also some high-level applications for demolition waste. For instance, crushed and sieved concrete demolition waste can be used as concrete aggregate instead of natural materials. Depending on the crushing process, about a third of the broken concrete is currently concrete sand. At present, concrete sand fraction (0-4 mm) is rarely reused as a concrete aggregate. This is due to the fact that some important characteristics of crushed concrete sand are different from those of natural sand. As a result, it does not reach the standards required for aggregates. Concrete containing such aggregate is of lower quality than concrete made of natural aggregate. This paper describes an experimental investigation on the treatment of concrete sand gained from demolition waste by wet processing using a jig whereby the sand is separated by grain size and, more importantly, by density. Concrete produced with concrete sand which has been treated in this manner should have the same quality as concrete prepared with natural aggregate. Recycled sand used as aggregate substitutes natural resources and avoids disposal of waste. It has all the characteristics of an Ecomaterial. (author abst.)

Refractory lifetimes are limited because of corrosion at higher temperatures. The best furnace lifetimes has been achieved with chromium oxide and chromium oxide corund refractories. Waste from the production and use of refractory material is generated in three main forms: as residues from cutting and grinding, as refractories which have limited or no contact with glass melts, and as refractories with infiltration of sublimation residues or condensates. The waste material is classified as hazardous waste due to its chromium content. In this study, arc furnace technology was used for thermal treatment of the waste materials to enable recycling of refractory materials. (author abst.)

In Germany the composite liner is the main component of standard landfill cappings for municipal and hazardous waste landfills and the compacted clay liner (CCL) for landfills for inert or low-contamination waste. The composite liner is a technically highly effective but very expensive system. Research and experience has given rise to concern about the proper long-term performance of a conventional single CCL as a landfill capping. Therefore, alternative capping systems are discussed and applied for landfills and for the containment of contaminated sites. This paper gives an overview on various alternative engineered cappings and suitable systems for capping reflecting the state of the art and the expert view in Germany. According to the European Council Directive on the landfill of waste an impermeable mineral layer is recommended for the surface sealing of non-hazardous landfills and a composition of artificial sealing liner and impermeable mineral layer for hazardous landfills. In both cases a drainage layer thickness of at least 0.5 m is suggested. These recommendations should be interpreted flexibly and to some extent modified in the light of the experience and results presented in this paper.

The largest fraction is construction and demolition waste (C&D waste) with some 54%. The treatment processes for C&D waste differ from those for municipal solid waste. According to the European Directive on Waste a waste hierarchy shall apply where recycling has a higher priority than energy recovery. A thermal treatment is regarded as recovery operation only if the energy efficiency is above a certain limit. Under the terms of the directive a simplified calculation of the energy efficiency is perfomed using the so-called R1 formula. Published data on heat and power production of several thermal waste treatment plants are compared to the R1 formula and data from literature. Amount and waste management options for different waste fractions and how to evaluate different waste management processes are discussed.

Im Jahr 2008 betrug der direkte Materialeinsatz (direct material input, DMI) (Czichos et al., 2008) in Deutschland 1687 Millionen Tonnen (Daten von destatis, 2010). Dazu gehören Energieträger (Kohle, Öl, Gas), Erze, Baumaterialien, Industrieminerale und Biomasse. Knapp 36 % davon (605 Millionen t) werden importiert. Mit zu berücksichtigen sind bei den Materialflüssen auch die nicht verwerteten Rohstoffentnahmen (z.B. Abraum im Bergbau, Bodenaushub, Bergematerial, Verbleib von Holzabfallen im Wald), die sich für die inländische Rohstoflentnahme auf 2229 Millionen Tonnen beliefen. Die nicht verwerteten Rohstoffentnahmen bei den Importen sind mehr als der Faktor 4 höher (2543 Millionen t) (Buyny et al., 2009). Auf der Outputseite geht von diesen riesigen Mengen der größere Anteil in den Bestand (net addition to stock, 637 Millionen t), der nächst größere Anteil in den Export (388 Mt). Immerhin 256 Millionen Tonnen werden durch dissipative Nutzung in der Umwelt verteilt. Die Bilanz geht auf, wenn man Gase auf der Inputseite und Emissionen in die Atmosphäre auf der Outputseite (Verbrennung von fossilen Rohstoffen zu CO2 und Wasser) berücksichtigt.

A two steps thermal treatment is suggested based on 1. mono-incineration of sewage sludge under destruction of organic pollutants and 2. thermochemical treatment of the resulting ashes to remove heavy metals and increase P-bioavailability. The targeted products are marketable P-fertilisers. The thermochemical treatment was investigated in a gas tight lab-scale rotary furnace. Seven sewage sludge ashes of different origin and composition and one residue from gasification of sewage sludge were mixed with a chlorine donor (e.g. MgCl2) and thermochemically treated under systematic variation of operational parameters. The distributions of the heavy metals between solid and gas phase were determined. The heavy metals concentrations of the treated ashes met the legislative limits in most cases. The products from thermochemical treatment are suited raw materials for P-fertiliser production.

In order to evaluate different leaching procedures, batch extraction tests and percolation tests were performed using three reference materials produced from contaminated soil, demolition waste and municipal solid waste incinerator bottom ash. Emphasis was placed on the investigation of the leachability of the heavy metals copper and chromium, polycyclic aromatic hydrocarbons (PAHs) and the anions chloride and sulfate. Significant discrepancies between column experiments and batch/extraction tests were found for the release of PAHs and to a lesser extent for the heavy metals Cu and Cr. Additionally interlaboratory comparisons were conducted based on different leaching tests with the reference materials and evaluated using the criteria of comparability and reproducibility. The best reproducibility was achieved for all investigated substances in column tests. The reproducibility of batch tests was acceptable except for PAHs. The results from the experimental work will help establish standardized and feasible laboratory procedures as fundamental for substance specific risk assessment of contaminated sites.

The main factor influencing the removal processes is the composition of the groundwater, namely the concentration of Ca and carbonate. Sorption of U onto the HAP surface seems to be the dominant removal process with the possibility of remobilisation. Newly formed U-phosphate minerals were detected by ESEM/EDX and XRD in samples with high U content indicating either a dissolution-precipitation mechanism or sorption onto the apatite surface followed by alteration of the structure. The formed U-phosphate minerals are stable under common groundwater conditions and can be remobilised only at high pH-values and high carbonate concentrations.

The interlaboratory comparisons of column percolation tests showed good reproducibility of the results for inorganic and organic parameters as well as for the accompanying parameters. This is due to the stipulations concerning the time of contact between leachant and sample material as well as the sample placement in the columns.

A two-step thermal treatment is suggested, including mono-incineration of sewage sludge and subsequent thermochemical treatment of the ashes. Organic pollutants are completely destroyed by mono-incineration. The resulting sewage sludge ashes contain P, but also heavy metals. P in the ashes exhibits low bioavailability, a disadvantage in farming. Therefore, in a second thermochemical step, P is transferred into mineral phases available for plants, and heavy metals are removed as well. The thermochemical treatment was investigated in a laboratory-scale rotary furnace by treating seven different sewage sludge ashes under systematic variation of operational parameters. Heavy metal removal and the increase of the P-bioavailability were the focus of the investigation. The present experimental study shows that these objectives have been achieved with the proposed process. The P-bioavailability was significantly increased due to the formation of new mineral phases such as chlorapatite, farringtonite and stanfieldite during thermochemical treatment.

The use of secondary raw material gains more importance since ore grade in primary production is decreasing. Meanwhile urban stock contains considerable amounts of various elements. Photovoltaic (PV) generating systems are part of the urban stock and recycling technologies for PV thin film modules with CdTe as semiconductor are needed because cadmium could cause hazardous environmental impact and tellurium is a scarce element where future supply might be constrained. The paper describes a sequence of mechanical processing techniques for end-of-life PV thin film modules consisting of sandblasting and flotation. Separation of the semiconductor material from the glass surface was possible, however, enrichment and yield of valuables in the flotation step were non-satisfying. Nevertheless, recovery of valuable metals from urban stock is a viable method for the extension of the availability of limited natural resources.

While column testing can provide a closer approximation to field percolation conditions than batch testing, there is still a need to develop column testing procedures that consider the requirements of practical testing time frames. This study evaluates the effect of different column contact times (2.5, 5, and 16 h) on the release of inorganic constituents from bottom ash and demolition waste, two commonly reused granular materials. Leaching data for representative constituents of concern, such as copper, chromium, sulfate and chloride, as well as pH and electrical conductivity was compared for all different contact times studied. Results for the materials investigated in this study showed that variations in contact time have no significant effect on the release of the selected constituents and leaching parameters at low liquid to solid ratios. However, after a liquid to solid ratio of 1 L/kg, the effect is more noticeable, and higher contact times show lower pH values as well as a reduction in the release of constituents of concern from bottom ash. In the case of demolition waste, the variation of contact time did not have a strong effect on the leaching behavior.

T1 - Leaching experiments on the release of heavy metals and PAH from C&D waste and MSWI bottom ash N2 - Leaching tests are fundamental tools for the assessment of long-term impact of contaminated waste materials on the soil-groundwater pathway. Waste materials should be tested under conditions equal to their actual application in re-use scenarios to achieve reliable results. Since the standards for leaching procedures available on international level so far are either not validated or considered inadequate in respect to coarse grained materials, new standards had to be developed. Therefore column percolation and batch test procedures have been standardized and validated to enable their introduction to new German regulations concerning waste management. Practical aspects of the test procedures as well as the boundary conditions compared to the already existing standards will be described. Examples including round robin test results will be given to justify the selection of the new specifications.

T1 - A Novel Dry Treatment for Municipal Solid Waste Incineration Bottom Ash for the Reduction of Salts and Potential Toxic Elements N2 - The main obstacle to bottom ash (BA) being used as a recycling aggregate is the content of salts and potential toxic elements (PTEs), concentrated in a layer that coats BA particles. This work presents a dry treatment for the removal of salts and PTEs from BA particles. Two pilotscale abrasion units (with/without the removal of the fine particles) were fed with different BA samples. The performance of the abrasion tests was assessed through the analyses of particle size and moisture, and that of the column leaching tests at solid-to-liquid ratios between 0.3 and 4. The results were: the particle-size distribution of the treated materials was homogeneous (25 wt % had dimensions <6.3 mm) and their moisture halved, as well as the electrical conductivity of the leachates. A significant decrease was observed in the leachates of the treated BA for sulphates (44%), chlorides (26%), and PTEs (53% Cr, 60% Cu and 8% Mo). The statistical analysis revealed good correlations between chloride and sulphate concentrations in the leachates with Ba, Cu, Mo, and Sr, illustrating the consistent behavior of the major and minor components of the layer surrounding BA particles. In conclusion, the tested process could be considered as promising for the improvement of BA valorization.

T1 - Per- und polyfluorierte Alkylsubstanzen (PFAS) im Klärschlamm N2 - Per- and polyfluoroalkyl substances (PFAS) are a group of more than 4700 anionic and cationic anthrophonic substances which have been used extensively in a variety of products and industries due to their inert chemical stability and resistance to degradation by heat or acids. As a result of continuous use, mainly in aviation firefighting foams, thousands of industrial and military installations have been found to contain contaminated soil and groundwater resources. However, because of the continuous use of fluorinated consumer products, also effluents and sewage sludge from wastewater treatment plants (WWTPs) have been shown to be an important source of PFAS contamination into the aquatic environment. Resulting from recent stricter regulations and restrictions in the last years on the use of long chain (≥C8) PFAS, there is a significant shift in the chemical industry towards production of short (C4-C7) and ultrashort (C1-C3) chain alternatives. With the amendment of the Sewage Sludge Ordinance in 2017 the German legislation banned sewage sludge application on agricultural land, and by 2029/2032 sewage sludge will be completely prohibited from agricultural application. While environmental exposure of organic pollutants like PFAS, pesticides and pharmaceuticals are no longer desirable, phosphorus (P) from sewage sludge must still be used to produce high-quality P-fertilizers for a circular economy. Currently, plant-available P-fertilizers from sewage sludge/wastewater can be produced using a variety of treatment approaches including precipitation, leaching, and thermal treatment. However, the fate of legacy and emerging PFAS compounds during P leaching, precipitation and treatment from sewage sludge and wastewater is for the most parts still unknown.

For this study, wet-discharged bottom ash fine-fraction samples from full-scale treatment plants in Germany and Sweden were analyzed. The potential for the recovery of heavy metal compounds was investigated through wet density-separation with a shaking table. The feed materials were processed without any pre-treatment and the optimum processing conditions were determined by means of design of experiments. Tilt angle and stroke frequency were identified as the most relevant parameters, and the optimum settings were − 7.5° and 266 rpm, respectively. The obtained balanced copper enrichments (and yields) were 4.4 (41%), 6.2 (28%) and 2.4 (23%). A maximum copper enrichment of 14.5 with 2% yield was achieved, providing a concentrate containing 35.9 wt.% relevant heavy metal elements. This included 26.3 wt.% iron, 4.3 wt.% zinc and 3.8 wt.% copper. In conclusion, density separation with shaking tables can recover heavy metals from bottom ash fine fractions. Medium levels of heavy metal enrichment (e.g., for Cu 2.7–4.4) and yield (Cu: 26–41%) can be reached simultaneously. However, the separation performance also depends on the individual bottom ash sample.

T1 - Mini-review of waste-to-energy related air pollution and their limit value regulations in an international comparison N2 - The concept of circular economy supports mitigation of climate change and other environmental pressures to the planet. Circulating materials in anthropogenic processes come with the risk of accumulating hazardous substances and compounds. In this concept, waste incineration or waste-to-energy (WtE) is a necessary technology to remove these compounds from the life cycle. In this mini-review, contaminants of major importance in the flue gas from waste incineration plants and their environmental impact are discussed. Air pollution of WtE is often seen as the most relevant environmental impact of this treatment option. The emission values parameter set for different countries is presented and compared. The most stringent legally set of emission values could be found in parts of Europe and South Korea. Japan also permits similar strict values when authorising individual incineration plants. In North America, the values are partially less strict as the best available technologies in Europe suggest being possible. Emerging economies, such as India and China, have shown efforts to improve their environmental protection standards but still have room to improve. This could be set in relation to other industrial emitting processes and therefore could be used to assess the relevance of this industry sector to the national emission inventories.

Pooling the resources of more than 20 European and Russian funding agencies, more than 150 projects were funded with an estimated budget of about € 60 million. Being even larger than many thematic ERA.NETs, the ERA.Net RUS Plus has been the biggest and most successful regional ERA.NET so far. Indicating a strong demand for scientific cooperation, the smaller-scale projects funded within the ERA.Net RUS (Plus) calls perfectly complement Russian participation in the EU Framework Programmes. Not least of all, the ERA-Net RUS calls are examples of successful collaboration at a time when cooperation in other fields is complicated by the politically challenging situation. These calls contributed to keeping the communication channels open. Against this background a dedicated event in late 2021 highlighted what has been achieved within the first decade of the initiative. The project EI-GEO coordinated by BAM was selected as best practice project. The presentation displays the main results of the project and discusses the key success factors.

The method can be used to determine the speciation of inorganic and organic fluorides, without pre-treatment of solid samples. Therefore, XANES spectra of several inorganic fluorides as well as selected fluorinated organic compounds were recorded. While inorganic fluorides partially exhibit a variety of sharp spectral features in the XANES spectrum, almost all inspected organofluorine compounds show two distinct broad features at 688.5 and 692.0 eV. Moreover, the peak intensity ratio 688.5 eV/692.0 eV in the PFAS XANES spectrum can be inversely correlated to the chain length of the perfluoro sulfonic acid group. The detection of targeted PFAS by bulk-XANES spectroscopy in combination with linear combination fitting in soils and sewage sludges was not applicable due to the low organic fluorine to total fluorine ratio of the samples (0.01–1.84%). Nonetheless, direct analysis of pure PFAS revealed that analysis of organofluorine species might be achieved in higher concentrated samples. Furthermore, quantitative measurements by combustion ion chromatography (CIC) evaluated as sum parameters extractable organically bound fluorine (EOF) and total fluorine (TF) emphasize that besides soils, sewage sludges are a significant source of organic fluorine in agriculture (154–7209 μg/kg).

T1 - Material flow, economic and environmental assessment of municipal solid waste incineration bottom ash recycling potential in Europe N2 - In 2018 municipal solid waste (MSW) incineration in Europe produced nearly 19 Mt of bottom ash (BA); only 46 %-wt. was treated, often in poorly performing plants, leaving behind 10 Mt of untreated and unrecovered BA, destined to landfill. This work was based on the inventory of BA across Europe, and on the hypothesis to achieve complete BA valorisation through two assumptions: treating 100% BA and minimizing the loss of valuable fractions due to technical limitations of state-of-the-art processes in comparison to advanced innovative processes. The research involved three phases: characterization of potential secondary raw materials (metals and mineral fraction) currently lost from untreated (the surplus compared to treatment capacity) and unrecovered BA (the fine fraction) through material flow analysis; environmental assessment (energy balance and net GHG emissions) of complete BA valorisation; investigation of the economic feasibility of complete BA Valorisation through state-of-the-art technologies. The resulting 2.14 Mt loss of valuable materials included 1 Mt Mineral fraction and 0.97 Mt ferrous metals, mostly from untreated BA, and 0.18 Mt non-ferrous metals, mostly from unrecovered BA. The energy balance and GHGs emissions required by the treatment of the currently untreated and unrecovered fractions of BA resulted in energy and GHGs emissions savings. Economic profitability was driven by iron and copper recycling and avoided landfill fees. Profitability was achieved by two thirds of considered countries (average values: NPV 83 M€, ROI 20%, payback time 11 years) with BA mass flow exceeding 0.02 Mt.

However, leaching chloride, sulfate, and potentially harmful heavy metals may cause problems in using IBA in civil engineering. Investigating leaching behavior is crucial for the assessment of the environmental compatibility of IBA applications. Various test procedures are available for that purpose. In the present study, a long-term leaching test of a wet-mechanically treated IBA was performed in a lysimeter for almost six years. While concentrations of chloride, sulfate and the majority of the heavy metals started to decrease rapidly with progressive liquid-to-solid ratio (L/S), antimony (Sb) and vanadium (V) behaved differently. At the beginning of the lysimeter test, the Sb and V concentrations were low, but after approximately one year of operation at an L/S ratio of around 0.8 L/kg, a steady increase was observed. It was shown that this increase is the result of low Ca concentrations due to the formation of CaCO3. With the data, the solubility products from Ca-antimonate and Ca-vanadate were calculated. The unusual leaching behavior of Sb and V should be kept in mind when considering field scenarios and evaluating the impact on the environment.

T1 - A Novel Dry Treatment for Municipal Solid Waste Incineration Bottom Ash for the Reduction of Salts and Potential Toxic Elements N2 - The main obstacle to bottom ash (BA) being used as a recycling aggregate is the content of salts and potential toxic elements (PTEs), concentrated in a layer that coats BA particles. This work presents a dry treatment for the removal of salts and PTEs from BA particles. Two pilotscale abrasion units (with/without the removal of the fine particles) were fed with different BA samples. The performance of the abrasion tests was assessed through the analyses of particle size and moisture, and that of the column leaching tests at solid-to-liquid ratios between 0.3 and 4. The results were: the particle-size distribution of the treated materials was homogeneous (25 wt % had dimensions <6.3 mm) and their moisture halved, as well as the electrical conductivity of the leachates. A significant decrease was observed in the leachates of the treated BA for sulphates (44%), chlorides (26%), and PTEs (53% Cr, 60% Cu and 8% Mo). The statistical analysis revealed good correlations between chloride and sulphate concentrations in the leachates with Ba, Cu, Mo, and Sr, illustrating the consistent behavior of the major and minor components of the layer surrounding BA particles. In conclusion, the tested process could be considered as promising for the improvement of BA valorization.

Weathering or any damage of constructions, as shown by a field study in Kaliningrad Oblast (Russia), could lead to the littering of the beach or the sea (marine littering) and the discharge of possibly harmful additives into the marine environment. The ageing behavior of a widely used geotextile made of polypropylene was studied by artificial accelerated ageing in water-filled autoclaves at temperatures of 30 to 80° C and pressures of 10 to 50 bar. Tensile strength tests were used to evaluate the progress of ageing, concluding that temperature rather than pressure was the main factor influencing the ageing of geotextiles. Using a modified Arrhenius equation, it was possible to calculate the half-life for the loss of 50% of the strain, which corresponds to approximately 330 years.

In a previous study, we performed a long-term leaching test of MSWI-BA in a lysimeter for almost six years to investigate the efficiency of the treatment process on the release of hazardous substances.

Within a joint research project in cooperation with a medium-sized enterprise, the preparation and characterization of “reactive” geomembranes and geotextiles modified by the addition of zero-valent metal nanoparticles was performed. Zero-valent iron (ZVI) nanoparticles were added to polyethylene or to the fillings of geo-containers or geosynthetic clay liners. These geosynthetic products consist of mixtures of sand with clay or bentonite, typically embedded in geotextile nonwovens or geomats. The permeability of these geo-containers can be adjusted by the ratio of clay or bentonite to sand. ZVI nanoparticles were also added as reactive material to geomembranes made of polyethylene with additives like the antioxidant Irganox 1010 or glycerin. These additives prohibit oxidation of the nanoparticle and act as hydrogen donor in the dechlorination of chlorinated hydrocarbons. Contaminates such as chlorinated hydrocarbons and toxic heavy metal compounds are either decomposed or converted to less toxic species (e.g. Cr-(VI) reduction to Cr-(III)). The paper reports the first experimental results from manufacturing of the reactive geomembrane model materials and characterization of the products with microscopic techniques. First breakthrough measurements of the ZVI modified geomembrane compared to a reference sample are presented.

As different copper species have in general a higher density compared to the prevalent minerals, processes for density separation seemed to be favorable for the recovery of copper. Investigations with a centrifugal classifier were therefore carried out with BA from MWSI which have been used for a few years as the covering material for a landfill. The results show an appreciable enrichment of the precious copper. The concentrates contained up to 60 mg/kg copper in the dry weight (DW) (in general about 30 – 40 mg/kg DW) with enrichment factors of around 20 and a copper recovery of up to 50 % (in general around 20 %). A test series in order to evaluate the potential benefit for sequential processing illustrate the low efficiency for a further processing of the tailings.

The fine fraction < 4 mm additionally contains chemically bound metals (oxides, carbonates, silicates). Separation prospects with techniques as in ore processing (flotation, density separation, bioleaching, hydrothermal solution) are discussed. During alteration after wet extraction mineral material with hydraulic properties form coatings on almost all particles of the bottom ash and complicate separation procedures. In addition bottom ash from MSWI is a heterogeneous material. For sufficient enrichment different concerted treatment steps seemed to be essential associated with an uncertainty of economic viability. The utilisation of metal compounds present in bottom ash as secondary raw material depends on the energy- and resource-efficiency of the enrichment processes. Therefore energy and material flow considerations are presented.

A. T1 - A novel approach for the recycling of thin film photovoltaic modules N2 - A sustainable recycling of photovoltaic (PV) thin film modules gains in importance due to the considerable growing of the PV market and the increasing scarcity of the resources for semiconductor materials. The paper presents the development of two strategies for thin film PV recycling based on (wet) mechanical processing for broken modules, and combined thermal and mechanical methods for end-of-life modules. The feasibility of the processing steps was demonstrated in laboratory scale as well as in semi-technical scale using the example of CdTe and CIS modules. Pre-concentrated valuables In and Te from wet mechanical processing can be purified to the appropriate grade for the production of new modules. An advantage of the wet mechanical processing in comparison to the conventional procedure might be the usage of no or a small amount of chemicals during the several steps. Some measures are necessary in order to increase the efficiency of the wet mechanical processing regarding the improvement of the valuable yield and the related enrichment of the semiconductor material. The investigation of the environmental impacts of both recycling strategies indicates that the strategy, which includes wet mechanical separation, has clear advantages in comparison to the thermal treatment or disposal on landfills.

Experiments were carried out in the framework of standardization and validation of column percolation and batch test procedures, in particular concerning the stipulation of the experimental setup. The colloid release of column and batch experiments was compared and the influence of different column filling heights (12.5–50 cm) on the release of polycyclic aromatic hydrocarbons (PAH) from soil was studied, as well as the effect of varying contact times (2.5–16 h) on the release of chromium from construction and demolition (C&D) waste and municipal solid waste incineration (MSWI) bottom ash. The results indicate that filtration of the eluate, which is required for batch tests, does not always allow the simulation of the actual colloid amount in soil pore water. Medium column heights four times the inner diameter of the column seemed to provide reasonable equilibrium adjustment conditions and avoid major biodegradation. The release of chromium was only marginally affected by the contact time, varied between 0.115 and 0.150 mg/kg for demolition waste eluate at a liquid-to-solid ratio of approximately 5 L/kg.

The ash was thermochemically treated in a lab-scale rotary furnace after mixing it with a chlorine-donor, either CaCl2 or MgCl2. Within each of these two sample series only a single process parameter, the reaction temperature, was varied, namely between 350 and 1050°C. It was found, that among the numerous crystalline phases present in the raw ash only quartz and hematite continue to exist after thermochemical treatments carried out at 1050°C, whereas all other components undergo at least one decomposition-recrystallization cycle. Some of the components re-crystallize even several times. It was proved that the restructuring of the calcium- and phosphorus-bearing mineral phases proceeds via the formation of chlorspodioside, Ca2PO4Cl. The influence of the type of chlorine-donor on the final product was elucidated in detail and - to the best of our knowledge - for the first time crystalline AlPO4 was found in a sewage sludge ash and its decomposition was investigated, too.

In most cases, it is not possible to quantify the extent of such negative impacts. However, the external cost of uranium mining in Germany can be estimated at 30 Euro/kg U. The environmental impact can be reduced when waste materials are processed, so that their use as a secondary raw material, substituting for natural resources, is possible. The recyclability of waste materials depends on the price of a resource and the concentration of the component in the waste.

To deal with this unceasing mass flow in an ecologically and economically responsible way a comprehensive chemical and structural characterization of all types of SSA is needed. X-ray powder diffraction (XRD) is one of the most promising analytical methods for this task. Although, there has been ample chemical evidence showing that many SSA contain aluminium phosphate as a major component up to now no aluminium phosphate or aluminium-rich mixed phosphate phase has been reported to be identified by XRD in a SSA produced at a mono-incineration facility. The outcome of the present com-bined XRD and Mossbauer spectroscopy investigation provides comprehensive evidence closing this gap for the first time.

T1 - Recovery of metals from waste, an example for the resource cycle N2 - Bottom ash from municipal solid waste incineration (MSWI) consists of eiemental metals in considerable amounts. The fine fraction < 4 mm additionally contains chemically bound metals (oxides, carbonates, Silicates). Separation prospects with techniques as in ore processing (flotation, density separation, bioleaching, hydrothermal solution) are discussed. During alteration after wet extraction mineral material with hydraulic properties form coatings on almost all particles of the bottom ash and complicate separation procedures. ln addition bottom ash from MSWI is a heterogeneaus material. For sufficient enrichment different concerted treatment steps seemed to be essential associated with an uncertainty of economic viability. The utilisation of metal compounds present in bottom ash as secondary raw material depends on the energy- and resource-efficiency of the enrichment processes. Therefore energy and material flow considerations are presented.

To be able to ponder about the equivalency of products with respect to their properties, all relevant properties have to be known. Therefore, additional tests based on the DepV-list of criteria and mechanisms of action (Annex 1, no. 2.1.1) are necessary for CE-marked products. This was discussed in the first part of this article. In this part, the tables C1, C2 and D of the first part, which listed and compared the requirements of the hEN and the DepV, are discussed in more technical details.

Hersteller, Bauherren, Planer und zuständige Behörden werden sich daher die Frage stellen, ob diese Produkte auf der Grundlage von Anhang 1 Nummer 2.1 Satz 7 Ziffer 1 der Deponieverordnung (DepV) im Deponiebau auch ohne Zulassung verwendet werden dürfen. Ein Vergleich der europäisch harmonisierten Bauproduktnormen DIN EN 13252 und DIN EN 13257, die der CE-Kennzeichnung der Geotextilien und geotextilverwandten Produkte zugrunde liegen, mit den Anforderungen der DepV zeigt nun aber, dass nur ein Teil der für den Deponiebau wesentlichen technischen Eigenschaften in diesen Normen erfasst werden. Daher sind für CE gekennzeichnete Produkte zusätzliche Prüfungen auf der Grundlage der DepV-Liste der Kriterien und Einwirkmechanismen erforderlich. Die in den Produktnormen beschriebene Qualitätssicherung ist nach Anhang 1 Nummer 2 Satz 14 ff der DepV ebenfalls für die Gleichwertigkeit nicht ausreichend. Eine CE-Kennzeichnung ist deshalb noch kein Nachweis, dass die Produkte dem Stand der Technik nach der DepV entsprechen und die Eigenschaften der Produkte den geforderten Eigenschaften im Wesentlichen gleichwertig sind, auch wenn mit Bezug auf den Anhang B der genannten Normen deren Dauerhaftigkeit für 100 Jahre vom Hersteller deklariert wird.---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- In the near future, CE-marked woven and nonwoven geotextiles, geocomposite drains and geogrids will be available on the market, whose declaration of performance will contain the qualification 'predicted service life up to 100 years' or even 'predicted service life minimum 100 years'. Manufacturer, principals and their design engineers as well as the responsible authorities will have to deal with the question, whether such products can be used on the basis of Annex 1, no. 2.1, sentence 7, cipher 1 of the German landfill ordinance (DepV) as components of landfill liner and capping systems. A comparison of the harmonized European standards hEN 13252 and 13257, on which the CE-marking of geotextiles and geotextile-related products is based, with the DepV, shows that only a few of the essential technical characteristics actually relevant for landfill constructions are considered in these standards. Therefore, additional tests based on the DepV-list of criteria and mechanisms of action are necessary for CE-marked products. Requirements on quality managements in the hEN are likewise not adequate for essential equivalence with respect to annex 1, No. 2.1, sentence 14 ff, DepV. Therefore, CE-marking is actually no proof of the fulfilment of the state of the techno logy according to the DepV and of the essential equivalence of product properties to the required properties, albeit the declaration of performance indicates a predicted service life of 100 years.

T1 - Effective cleanup of groundwater contaminated with radionuclides using permeable reactive barriers N2 - The mining of natural resources always causes environmental impacts such as land use, large quantities of waste, destruction of habitat, impairment of groundwater regime, and quite possibly contamination of soil, water, or air (Dudka and Adriano 1997). The environmental impact of mining cannot be estimated easily. The concept of total material requirement (TMR) is an attempt to quantify the environmental impact of materials. TMR is the sum of domestic and imported primary natural resources and their hidden flows (Adriaanse et al. 1997). Hidden flows are often not considered in environmental analyses because they are attributed with no cost. However, overburden from mining, earth moving for construction, and soil erosion are major sources of ecological damage. From the mining of minerals to the final products, a number of process steps take place (exploration, mine site development, extraction, milling, washing, concentration, smelting, refining, fabrication), each step being connected to other input flows such as energy or other resources. The hidden flows for metals related to metal ore mining have been investigated by Halada et al. (2001). Table 9.1 lists the data for some metals, together with the data for some other minerals and fuels. The TMR in the United States in the 1990s was between 80 and 100 tonnes per capita; in the European Union (EU-15) approximately 50 tonnes per capita (Bringezu 2002).

Currently only 8 % of metals (of these 1 % are non-ferrous metals) are recovered from MSWI BA. For characterization of recovery potential, MSWI BA samples have to be taken, pre-treated and analyzed according to standardized methods. This manuscript focuses on sample pre-treatment and preparation of a MSWI BA sample aiming to investigate the characteristics transfer over the process of sub-sampling from the original (field) sample to the laboratory sample, test sample until the analytical sample. All results have been evaluated with statistical methods. The results show that influence of each single pre-treatment and preparation step on metal content differs for the individual metals. For lead a conservation of characteristics distribution can be observed, while for copper a continuous decline of solid concentration is observed over all preparation steps. One possible reason may be the fact that copper is mainly contained in the fine fraction as metallic copper with specific properties.

In order to increase the recovery rates of metals or to achieve a higher quality of mineral aggregates derived from BA, new procedures have been either implemented to existing plants or completely new treatment plants have been built recently. Three treatment trains, which are designated as entire sequences of selected processing techniques of BA, are introduced and compared. One treatment train is mainly characterized by usage of a high speed rotation accelerator whereas another is operating completely without crushing. In the third treatment train the BA is processed wet directly after incineration. The consequences for recovered metal fractions and the constitution of remaining mineral aggregates are discussed in the context of legislative and economical frameworks. Today the recycling or disposal options of mineral residues still have a high influence on the configuration and the operation mode of the treatment trains of BA despite of the high value of recovered metals.

By cleaning used brushes under the tap cadmium can enter the food chain via waste water treatment and subsequent agricultural application of the sewage sludge. It was estimated that 110 kg Cd per year is spread on agricultural land via this exposure route. Other sources of Cd amount to almost 120 tons per year. The mobility of Cd from pigments was studied in a field-like scenario by leaching experiments using soil samples amended with sewage sludge and spiked with Cd pigments in percolation columns. The redox conditions were confirmed to be the decisive factor for the release of Cd. The release of Cd from artists’ paints was in most cases 1% or lower in the experiments performed. Cd from artists’ paints in sewage sludge applied in agriculture will be mobilized for intake by crops or to leaching either by oxidation of sulfide to sulfate or by dissolution at lower pH values. The quantity of Cd from artists’ paints calculated in the restriction dossier is however negligible compared to other sources of Cd to agricultural soil. Therefore ECHA did not consider the proposed restriction to be the most appropriate EU wide measure to address the negligible level of risk. In the presentation sources of Cd on agricultural land will be discussed together with possible policy instruments to mitigate such emissions.

Dazu gehören die vollständige Rückgewinnung der metallischen Phase, die in die Edelstahlherstellung zurückgeführt werden kann, sowie die Aufwertung der mineralischen Fraktion, die ihre uneingeschränkte Verwendung als Zementzumahlstoff oder mineralischer Baustoff erlaubt. Bei geeigneter Prozessführung des elektrischen Lichtbogenofens können durch „reduzierendes Schmelzen“ die chromhaltigen Wertstoffe zusammen mit anderen Schwermetallen zu 97% in einer Metalllegierung angereichert und separiert werden. Diese kann als Rohstoff in der Metallurgie eingesetzt werden. Der Chromgehalt der mineralischen Komponte der Schlacke konnte von ca. 3% auf unter 0,1% verringert werden. Die mineralische Fraktion lässt sich durch entsprechende Zuschläge während des Schmelzbetriebes und eine anschließende Granulation der schmelzflüssigen Phase zu einem Material aufwerten, das in seiner Zusammensetzung und seinen Eigenschaften typischen Zementkomponenten entspricht und als Rohstoff in der Zementproduktion eingesetzt werden kann. Dafür müssen allerdings noch die rechtlichen Voraussetzungen geschaffen werden, da der Rohstoffeinsatz gerade im Zement strengen Auflagen unterliegt und die Zemente bestimmte Normen erfüllen müssen. Durch die in RECARC aufgezeigte Möglichkeit der Wiederverwertung können somit Stoffkreisläufe geschlossen werden, die ansonsten zu einem Verlust wertvoller Rohstoffe führen.

Regarding the growing number of installed photovoltaic systems, the end-of-life management of the pv-modules will become increasingly important. Thin film panels contain hazardous substances that may harm the environment if they are not recycled or disposed properly after reaching the end of their service life. Heavy metals, for example, can be toxic as well as carcinogenic or teratogenic. Processing methods for the recycling of PV thin film modules have to take these facts into account. Currently the available recycling techniques usually utilise chemicals such as acids for a wet-chemical treatment of end-of-life modules. The aim of RESOLVED was to identify and test alternative methods for a wet-mechanical treatment in order to reduce the consumption of chemicals in the recycling of thin film modules. Furthermore, the recovered Cadmium-Telluride (CdTe) and Copper-Indium-Diselenide/Disulfide (CIS) should be helping to save scare resources especially for limited elements such as tellurium and indium. The project RESOLVED investigated the recovery of semiconductors material as secondary raw material and the decontamination of the residues of the PV thin film modules. These goals were achieved by testing and optimising existing technologies for the recycling process as well as for the enrichment of the semiconductor materials. The target is to re-use the enriched recovered material in the production of new PV modules. Special efforts were made to look into life cycle analysis, process sustainability, economical aspects, and resource availability.

In 14 European countries contamination caused by uranium represents a particularly serious danger where drinking water resources might be affected. Other heavy metals and organic pollutants can also have a strongly deleterious effect on groundwater. Available technologies (e.g. pump- and-treat) fall short of solving the problem because their performance is not yet adequate for effective remediation. The aim of the project is to elaborate the scientific basis for laboratory and pilot-scale testing of and the practical application of a considerably more efficient and cost-effective in-situ reactive barrier technology targeting the above contaminants. The primary model test site will be an area in Southern Hungary contaminated by uranium mining- thus including a region which is due to become part of the European Union. The approach taken to meet the project objectives was the characterisation of different reactive materials and relevant attenuation processes in the reactive matrix of the permeable barrier with special respect to their long-term behaviour. The experimental work included laboratory experiments at different scales, going from bench-scale tests up to pilot-scale, and field-scale experiments. Experimental conditions were predetermined by the characteristics of the model site, such as geologic and hydrogeological settings, soil composition, and type, extent and spreading of the contamination. Technological methods to enhance the long-term efficacy and cost-effectiveness of permeable reactive barrier systems were developed and tested under realistic conditions.

However, due to the rapid expansion of offshore wind energy, rising water levels and more extreme weather conditions as a result of climate change more and more hydraulic engineering projects will be realized in the future. Construction with geosynthetics has various advantages, but it has to be ensured that there is no negative environmental impact from the application of geosynthetics in hydraulic engineering.

Here, the sorption behavior of the fuel-related water contaminants benzene, toluene, ethyl benzene and xylene (BTEX) and four tertiary butyl ethers to virgin and via UV radiation aged polypropylene (PP) and polystyrene (PS) pellets was investigated. Changes in material properties due to aging were recorded using appropriate polymer characterization methods, such as differential scanning calorimetry, Fourier transform infrared spectroscopy, gel permeation chromatography, X-ray photoelectron spectroscopy, and microscopy. Pellets were exposed to water containing BTEX and the ethers at 130-190 mg/L for up to two weeks. Aqueous sorbate concentrations were determined by headspace gas chromatography. Sorption to the polymers was correlated with the sorbate's Kow and was significant for BTEX and marginal for the ethers. Due to substantially lower glass transition temperatures, PP showed higher sorption than PS. Aging had no effect on the sorption behavior of PP. PS sorbed less BTEX after aging due to an oxidized surface layer.

Along with lower energy demand, the greenhouse gas emissions produced are also lower. The duty of a modern waste management system should therefore be to collect and sort the waste materials in a way that the highest amounts of single material fractions with the highest qualities can be generated. In this contribution, the greenhouse gas balances of the theoretical treatment of the household waste, if collected as mixed waste in sanitary landfills, in waste incineration plants, or in mechanical-biological treatment plants, are compared to the existing separate waste collection and treatment in Germany in 2014. The results show that the treatment of the mixed collected household waste in sanitary landfills would lead to a significant release of greenhouse gases. The treatment in MBTs with the recovery of valuables and the further disposal of the biologically stabilized fraction on landfills, as well as the treatment of the high calorific fraction (also called refuse derived fuel – RDF) in RDF plants, coal-fired power plants, or cement kilns, would lead to small amounts of avoided greenhouse gas emissions. The thermal treatment in waste incineration plants would lead to moderate amounts of avoided greenhouse gases. Only with the actually practiced separate collection and treatment of household waste were significant amounts of greenhouse gas emissions avoided. In total, this is approximately 5.5 million tons of carbon dioxide equivalents for approximately 45.5 million tons of separate collected and treated household waste in Germany in 2014.

T1 - Antimon in Rostaschen aus der Müllverbrennung – Auslaugverhalten und Rückschlüsse für die Aufbereitung N2 - Antimon (Sb) wird industriell vorwiegend als Flammschutzmittel in Kunststoffen verwendet. Am Ende des Lebenszyklus landet etwa die Hälfte des produzierten Sb, vorwiegend über entsprechend dotierte Kunststoffe, in Haus- und vor allem Industrieabfällen und in der Folge auch in relevanten Mengen in Rostaschen aus der Verbrennung dieser Abfälle. Zwar werden in den Produkten Sb-Verbindungen in der Oxidationsstufe 3 eingesetzt, in den Aschen liegt Sb jedoch wegen der leichten Oxidierbarkeit überwiegend in der Oxidationsstufe 5 als Oxyanion vor (Sb(OH)6- oder Sb2O74-). Die Freisetzung beim Kontakt mit Wasser ist zunächst gering, weil die Antimonate schwerlösliche Verbindungen mit Ca2+ bilden. Durch die Carbonatisierung der Aschen während der vorgeschalteten Lagerung sinkt der pH-Wert im Eluat. Die Konzentration von Ca im Eluat nimmt mit fortschreitender Elutionsdauer ab, wodurch sich das Lösungsgleichgewicht verschiebt und Antimonate gelöst werden können. Dieses Verhalten wird durch einen Langzeitversuch mit Lysimetern bestätigt. Experimentelle Daten aus unterschiedlichen Elutionstests wurden mit dem Solver-Modul in MS Excel gefittet. Daraus ergibt sich Ca(Sb(OH)6)2xCa0.78(OH)1.56 als mögliche Verbindung für in Rostaschen enthaltenes Ca-Antimonat. Laut Entwurf der MantelVO ist für Sb in Rostaschen eine Regulierung vorgesehen. Die darin vorgesehenen Grenzwerte könnten ein Problem für Rostaschen darstellen und gefährden die Verwertung der mineralischen Fraktion. In den meisten Bundesländern geschieht der Vollzug derzeit nach dem LAGA Merkblatt M20. Die darin festgelegten Parameter zur Bewertung berücksichtigen im Prinzip nur eine Richtung, bei der sich die Materialeigenschaften im Zuge der Alterung von Rostaschen verbessern. Dieser Zusammenhang ist bei Sb nicht gegeben, was bei der Beurteilung des Gefahrenpotentials aber Berücksichtigung finden sollte. Das entgegengesetzte Verhalten von Sb stellt Aufbereiter und Verwerter möglicherweise vor Probleme. Die Einführung einer Ersatzbaustoffverordnung im Rahmen der MantelVO soll bundeseinheitliche Rechtssicherheit bei der Verwertung von mineralischen Recyclingmaterialien schaffen. Damit würde dann auch eine Grundlage für Investitionen in verbesserte Aufbereitungsverfahren geschaffen werden. Da im Hinblick auf Sb aus dargestellten Zusammenhängen jedoch eher das Gegenteil zu befürchten ist, besteht Forschungsbedarf, um dieses Problem zu lösen.

N2 - The potential release of hazardous substances from polymer-based products is currently in the focus of environmental policy. Environmental simulations are applied to expose such products to selected aging conditions and to investigate release processes. Commonly applied aging exposure types such as solar and UV radiation in combination with water contact, corrosive gases, and soil contact as well as expected general effects on polymers and additional ingredients of polymer-based products are described. The release of substances is based on mass-transfer processes to the material surfaces. Experimental approaches to investigate transport processes that are caused by water contact are presented. For tailoring the tests, relevant aging exposure types and release quantification methods must be combined appropriately. Several studies on the release of hazardous substances such as metals, polyaromatic hydrocarbons, flame retardants, antioxidants, and carbon nanotubes from polymers are summarized exemplarily. Differences between natural and artificial exposure tests are discussed and demonstrated for the release of flame retardants from several polymers and for biocides from paints. Requirements and limitations to apply results from short-term artificial environmental exposure tests to predict long-term environmental behavior of polymers are presented.

Dabei wurden auch die Auswirkungen der Umstellung des Elutionsverfahrens von einem Wasser-Feststoffverhältnis (W/F) von 10 l/kg auf ein W/F von 2 l/kg auf die Einstufung von Bodenmaterialien betrachtet. Insbesondere für die Stoffgruppe der PAK konnte gezeigt werden, dass sich mit Verabschiedung der neuen Regelungen zusätzliche Verwertungsmöglichkeiten von Bodenmaterialien außerhalb der durchwurzelbaren Bodenschicht eröffnen und deren Deponierung teilweise vermieden werden kann.

T1 - What waste management can learn from the traditional mining sector: Towards an integrated assessment and reporting of anthropogenic resources N2 - Many organizations in Europe collect data and perform research on municipal solid waste and the secondary raw materials that can be produced from them through recycling, urban mining, or landfill mining.However, the information generated and presented thereby is often highly aggregated, while research activities are many a time isolated. Both reduce the usability of the data and information generated. In order to better structure the knowledge generation on secondary raw materials production from municipal solid waste, we suggest to learn from the traditional raw materials mining Industry how to perform an integrated assessment and reporting of anthropogenic resources. This is exemplarily shown for the case of the anthropogenic resource municipal solid waste incineration bottom ash and airpollution control residues. A network of expert institutions from countries throughout Europe was build up to compile the information on legal and technological aspects for the recovery of different secondary raw materials from these residues, including construction minerals, metals, and salts. We highlight in our article the strength of the combined knowledge of an expert network not only on legal and technological, but also local and site-specific aspects of the recovery of secondary raw materials. By doing so, we hope to kick-off a discussion for how to organize and implement a structure for a better management of knowledge on anthropogenic resources, in order to provide a sustainable supply of secondary raw materials for a greener and more circular economy.

T1 - EI‐GEO environmental impact of geosynthetics in aquatic systems N2 - EI‐GEO is a multinational research project (Germany, Latvia, Russia) funded under the ERA.Net RUS Plus Call 2017. Aim of the project is the investigation whether geosynthetics in hydraulic engineering applications could be a source of microplastics (MPs) and other contaminants to the aquatic environment causing negative effects to aquatic organisms. Whereas the behavior of geosynthetics in landfill engineering is well studied and documented since decades, little is known on application in applications such as coastal protection or ballast layers for wind energy plants. However, due to the rapid expansion of offshore wind energy, rising water levels and more extreme weather conditions as a result of climate change more and more hydraulic engineering projects will be realized in the future. Applied methods are artificial ageing of geosynthetics in environmental simulation chambers, storage of samples under environmental condition for comparison with laboratory simulation, sample characterization by microscopic methods and ecotoxicological testing of water in contact with geosynthetics. In parallel a case study at the Baltic Sea shore at Kaliningrad Oblast (Russia) will be performed. The aim of study is to estimate the level of pollution of the beaches by geosynthetic debris and identify the possible sources.

BA fractions obtained from wet-processing aiming at the improvement of environmental quality were used to investigate the mobility of relevant substances. Eluates from laboratory-scaled leaching procedures (column percolation and lysimeters) were analyzed to learn about the long-term release of substances. Unsaturated conditions and artificial rainwater (AR) were used in the lysimeter tests to simulate field conditions. In addition, batch test eluates were generated at usual liquid-to-solid ratios (L/S) for compliance testing purposes. A variety of cations and anions was measured in the eluates. The wet treatment reduces the leaching of chloride and particularly sulfate by more than 60%. The release of typical contaminants for the treated MSWI BA such as the heavy metals Cu and Cr was well below 1% in the conducted leaching tests. An increase in the Sb concentration observed in the lysimeter experiments starting at L/S 0.75 L/kg and in the column experiment at L/S 4 L/kg is assumed to be related to decreasing concentrations of Ca and thus to the dissolution of sparingly soluble calcium antimonate. The same leaching mechanism applies with V, but the concentration levels observed are less critical regarding relevant limit values. However, on the long term the behavior of Sb could be problematic for the application of MSWI BA in construction.

The exergy of bottom ash was calculated to be some 100 kJ/mol, mainly as a result of the presence of elemental Fe and Al. From this it can be shown that the recovery of elemental metals Cu, Al and Fe is beneficial. The fine fraction <4 mm additionally contains chemically bound metals (oxides, carbonates, silicates). Separation prospects with techniques as in ore processing (flotation, density separation, bioleaching, hydrothermal solution) are discussed. Although the concentration of Cu compounds in bottom ash is in the range of today’s exploited ores the economic viability of the recovery of metal compounds is uncertain.

These guidelines represent a framework that defines resource efficiency and outlines proposals for the producing industry. A special guideline for small and medium-sized enterprises (SMEs) is included as well as guidelines on methodologies for evaluating resource use indicators, such as the cumulative raw material demand of products and production systems. The work on resource use indicators is still in progress. The evaluation of raw materials expenditure will include water, soil and land use. The model will include the availability of raw materials (criticality). Improving resource efficiency at the end-of-life stage is illustrated in this paper by the example of materials recovery from waste, here from residues out of municipal solid waste incineration (MSWI).

Im Zusammenhang mit der Novellierung der Bundes-Bodenschutzverordnung und der Einführung der Ersatzbaustoffverordnung sowie in Auswertung der Ergebnisse des BMBF-Verbundvorhabens „Sickerwasserprognose“ wurden vom DIN-Normenaus-schuss Wasserwesen, Unterausschuss „Eluierungsverfahren“ zwei Verfahren zur Elution von Fest-stoffen erarbeitet, die im Oktober 2007 als Entwürfe veröffentlicht wurden. Dabei handelt es sich um ein Säulenperkolationsverfahren zur gemeinsamen Untersuchung des Elutionsverhaltens von orga-nischen und anorganischen Stoffen (E DIN 19528) und ein Schüttelverfahren mit einem Wasser-/ Feststoff-Verhältnis (W/F) von 2 l/kg zur Untersuchung der Elution von anorganischen Stoffen (E DIN 19529). Beide Verfahren sind für Bodenmaterialien und mineralische Abfälle mit einer Korngröße bis 32 mm vorgesehen. Für Normen die in Verordnungen zitiert werden sollen, ist eine Verfahrensvalidierung erforderlich. Im Rahmen dieses Vorhabens waren die Verfahrenskenndaten auf der Grundlage von Ringversuchen zu ermitteln. Zunächst wurden vier für die Verordnungen relevante Materialien (Hausmüllverbrennungs-asche, Recyclingbaustoff, Bodenmaterial, Stahlwerksschlacke) als Referenzmaterialien (RM) aufberei-tet. Die zu analysierenden Parameter wurden unter Berücksichtigung der Regelungsrelevanz in Abstimmung mit dem Auftraggeber ausgewählt. Die RM wurden gemeinsam mit Referenzlösungen an die 53 Teilnehmer der Ringversuche ausgegeben. Die statistische Auswertung der Ringversuchsergebnisse erfolgte nach DIN 38402-42, wobei der Gesamtmittelwert aller Teilneh-mer als Sollwert herangezogen wurde. Es konnte gezeigt werden, dass akzeptable Reproduzierbarkeiten für organische und anorganische Schadstoffe durch geeignete Vorgaben sowohl für Schütteltests als auch für Säulenversuche erzielt werden können. Dies gilt insbesondere unter Berücksichtigung des breiten Korngrößenspektrums der RM, der relativ hohen zugelassenen Toleranzen für das W/F bei den Säulenversuchen und des kurzen Bekanntheitsgrades der Normenentwürfe. Die ermittelten Verfahrenskenndaten finden Eingang in die abschließende Bearbeitung der Normen.

By cleaning used brushes under the tap cadmium can enter the food chain via waste water treatment and subsequent agricultural application of the sewage sludge. It was estimated that 110 kg Cd per year is spread on agricultural land via this exposure route. Other sources of Cd amount to almost 120 tons per year. Results: The mobility of Cd from pigments was studied in a field-like scenario by leaching experiments using soil samples amended with sewage sludge and spiked with Cd pigments in percolation columns. The redox conditions were confirmed to be the decisive factor for the release of Cd. The release of Cd from artists’ paints was in most cases 1% or lower in the experiments performed. Conclusions: Application of sewage sludge containing Cd from artist paints does not increase the amount of Cd leached from this soils. Furthermore the quantity of Cd from artists’ paints calculated in the restriction dossier is negligible compared to other sources of Cd to agricultural soil. Therefore ECHA did not consider the proposed restriction to be the most appropriate EU wide measure to address the negligible level of risk.

However, complex matrices especially characterized by slurry particles and dissolved organic matter (DOM) can hamper the extraction of PAH with both SBSE and SPME and lead to different results. Thus, we produced aqueous eluates from PAH-contaminated soils differing in particle size distribution and organic matter content and determined the PAH concentration in the eluates with both SBSE and SPME. Furthermore, we tested the influence of filtration on the PAH analysis. The excess finding of PAH with SBSE compared to SPME ranged from −16.6 to 24.5 %. The differences increased after filtration. We found a strong positive correlation of the excess finding to the total organic carbon content (TOC) and a negative one to the pH value. The results indicate that SBSE is less affected by complex matrices than SPME.

In order to increase the recovery rates of metals or to achieve a higher quality of mineral aggregates derived from BA, new procedures have been either implemented to existing plants or completely new treatment plants have been built recently. Three treatment trains, which are designated as entire sequences of selected processing techniques of BA, are introduced and compared. One treatment train is mainly characterized by usage of a high speed rotation accelerator whereas another is operating completely without crushing. In the third treatment train the BA is processed wet directly after incineration. The consequences for recovered metal fractions and the constitution of remaining mineral aggregates are discussed in the context of legislative and economical frameworks. Today the recycling or disposal options of mineral residues still have a high influence on the configuration and the operation mode of the treatment trains of BA despite of the high value of recovered metals.

T1 - Legal situation and current practice of waste incineration bottom ash utilisation in Europe N2 - Almost 500 municipal solid waste incineration plants in the EU, Norway and Switzerland generate about 17.6 Mt/a of incinerator bottom ash (IBA). IBA contains minerals and metals. Metals are mostly separated and sold to the scrap market and minerals are either disposed of in landfills or utilised in the construction sector. Since there is no uniform regulation for IBA utilisation at EU level, countries developed own rules with varying requirements for utilisation. As a result from a cooperation network between European experts an up-to-date overview of documents regulating IBA utilisation is presented. Furthermore, this work highlights the different requirements that have to be considered. Overall, 51 different parameters for the total content and 36 different parameters for the emission by leaching are defined. An analysis of the defined parameter reveals that leaching parameters are significantly more to be considered compared to total content parameters. In order to assess the leaching behaviour nine different leaching tests, including batch tests, up-flow percolation tests and one diffusion test (monolithic materials) are in place. A further discussion of leaching parameters showed that certain countries took over limit values initially defined for landfills for inert waste and adopted them for IBA utilisation. The overall utilisation rate of IBA in construction works is approximately 54 wt%. It is revealed that the rate of utilisation does not necessarily depend on how well regulated IBA utilisation is, but rather seems to be a result of political commitment for IBA recycling and economically interesting circumstances.

T1 - Metal recovery from incineration bottom ash: state-of-the-art and recent developments N2 - Municipal solid waste incineration (MSWI) is one of the leading technologies for municipal solid waste (MSW) treatment in Europe. Incineration bottom ash (IBA) is the main solid residue from MSWI, and its annual European production is about 20 million tons. The composition of IBA depends on the composition of the incinerated waste; therefore, it may contain significant amounts of ferrous and non-ferrous (NFe) metals as well as glass that can be recovered. Technologies for NFe metals recovery have emerged in IBA treatment since the 1990s and became common practice in many developed countries. Although the principles and used apparatus are nearly the same in all treatment trains, the differences in technological approaches to recovery of valuable components from IBA – with a special focus on NFe metals recovery – are summarized in this paper.

T1 - Sustainable remediation methods for metals and radionuclides N2 - Since it was realized that sites contaminated with metals and radionuclides needed treatment, various remediation methods have been and are being developed. Depending on the size of the contaminated site and urgency of intervention, conventional or recently introduced techniques have been used. Conventional techniques include excavation and removal for treatment of soil and contaminants, or the so-called “pump-and-treat” method, in which contaminated groundwater is removed from the ground by pumping and treated in a treatment plant on the surface. It has the advantage of using proven techniques and is easy to control, and the treated groundwater can be reinjected into the ground or discharged in rivers or lakes. Novel methods include permeable reactive barriers, biomineralization, and electrokinetic remediation.

Extractable (EOF) and adsorbable (AOF) organically bound fluorine as well as total fluorine (TF) were measured in samples fromriver Spree in Berlin, Germany, to reveal the advantages and disadvantages of the two techniques used as well as the two established fluorine sum Parameters AOF and EOF. TF concentrations determined via HR-CS-GFMAS and CIC were comparable between 148 and 270 μg/L. On average, AOF concentrations were higher than EOF concentrations, with AOF making up 0.14–0.81% of TF (determined using CIC) and EOF 0.04–0.28% of TF (determined using HR-CSGFMAS). The results obtained by the two independent methods were in good agreement. It turned out that HR-CS-GFMAS is a more sensitive and precise method for fluorine analysis compared to CIC. EOF and AOF are comparable tools in Risk evaluation for the emerging pollutants per- and polyfluorinated alkyl substances; however, EOF is much faster to conduct.

In order to mineralize PFAS pollutants, the incineration of contaminated material is a state-of-the-art process, but more cost-effective and sustainable technologies are inevitable for the future. Within this review, various methods for the reductive defluorination of PFASs were inspected. In addition to this, the role of mechanochemistry is highlighted with regard to its major potential in reductive defluorination reactions and degradation of pollutants. In order to get a comprehensive understanding of the involved reactions, their mechanistic pathways are pointed out. Comparisons between existing PFAS decomposition reactions and reductive approaches are discussed in detail, regarding their applicability in possible remediation processes. This article provides a solid overview of the most recent research methods and offers guidelines for future research directions.

Due to such additives in plastics, about a half of Sb ends up in municipal solid waste incineration at the end-of-life and consequently in relevant amounts in the generated bottom ash. In contact with water, the initial leachability is low, as antimonates form sparingly soluble compounds with Ca2+. Following the carbonation of the incineration bottom ash (IBA) during the proceeding ageing the pH in the leachates decreases. With decreasing concentration of Ca in the eluate the solution equilibrium changes and antimonates dissolve. In Germany it is intended to regulate Sb in IBA with the planned implementation of the so called Mantelverordnung (MantelVO, containing provisions on the utilisation of mineral waste) in the near future. The limit values set in the draft might be critical for IBA and therefore pose a risk for the utilisation of the mineral fraction of IBA in the well-established recycling routes.

Weathering or any damage of constructions, as shown by a field study in Kaliningrad Oblast (Russia), could lead to the littering of the beach or the sea (marine littering) and the discharge of possibly harmful additives into the marine environment. The ageing behavior of a widely used geotextile made of polypropylene was studied by artificial accelerated ageing in water-filled autoclaves at temperatures of 30 to 80 °C and pressures of 10 to 50 bar. Tensile strength tests were used to evaluate the progress of ageing, concluding that temperature rather than pressure was the main factor influencing the ageing of geotextiles. Using a modified Arrhenius equation, it was possible to calculate the half-life for the loss of 50% of the strain, which corresponds to approximately 330 years. Dynamic surface leaching and ecotoxicological tests were performed to determine the possible release of contaminants. No harmful effects on the test organisms were observed.

This work was based on the analysis of the baseline situation of MSW management in EU-28 in 2018, considering its progress in 2008–2018, and discussed the possible improvement perspectives based on a framework involving incineration and recycling as the only possible alternatives, specifically evaluating the capability of already-existing incineration plants to fulfill the EU needs in the proposed framework. The results of the assessment showed two main crucial issues that could play a pivotal role in the achievement of Circular Economy action plan targets: the need to increase the recycling quotas for specific MSW fractions through the separate collection, and therefore the improvement of definite treatment process chains; the optimization of the recovery of secondary raw materials from incineration bottom ash, involving the Recycling of ferrous and nonferrous metals and the mineral fraction. Both issues need to find an extensive application across all member states to decrease the actual differences in the adoption of sustainable MSW management options.

Bei insgesamt neun Projektpartnern fiel folgerichtig ein nicht unwesentlicher Aufwand für Verwaltungsaufgaben an. Insbesondere die Verzögerungen bei dem Bau der großtechnischen Anlagen im Teilprojekt B (ausführlich erläutert im Bericht für das Gesamtvorhaben) resultierten in einer Vielzahl von Folgeaufgaben. Wissenschaftlich verfahrenstechnisches Ziel des Teilprojektes A bei der BAM war die Rückgewinnung von Metallen und metallischer Verbindungen aus speziellen, bereits teilaufbereiteten Fraktionen von Aschen aus der Hausmüllverbrennung (HMVA). Ausgangsmaterial sollten Fraktionen sein, die im Rahmen des Projektes vom Projektpartner TARTECH eco industries AG bereitgestellt werden sollten. Eigens und im Rahmen des Projektes entwickelte Hochgeschwindigkeits-Rotations- Beschleuniger sollten die mineralischen Oberflächenverkrustungen abschlagen, die einzelnen Bestandteile trennen und so eine effizientere Sortierung mit Anschlussverfahren ermöglichen. Die Verfahren, die bei der BAM dafür zum Einsatz kamen, waren im Wesentlichen Flotation und Dichtesortierung mittels eines Zentrifugalsortierers. Der Fokus der Untersuchungen lag dabei auf der Rückgewinnung bzw. Anreicherung von Kupfer und Kupferverbindungen.

T1 - Bedingungen suffosiver Erosionsphänomene in Böden N2 - Für eine detaillierte Analyse der Gefüge- und Porenstruktur weitgestufter Erdstoffe ist es notwendig, diese dreidimensional (3D) zu visualisieren und ihre Kenngrößen zu ermitteln. Dazu wurde an der BAM eine Präparationsmethode entwickelt, die es ermöglicht die Porenstruktur von Probenkörpern aus suffosiven Erdstoffen und definierten Korngrößenverteilungen über CT-Aufnahmen abzubilden. Über eine eigens dafür, in Zusammenarbeit mit dem Zuse-Institut Berlin (ZIB), entwickelte Bildanalysemethode wurden die Strukturdaten visualisiert. Aus dem Bilddatensatz konnte bereits in der Rückwärtsrechnung eine Kornverteilungslinie zur Validierung generiert und mit experimentell ermittelten Sieblinien verglichen werden. Des Weiteren wurden in Säulenexperimenten Kornumlagerungsprozesse unter der Verwendung von CT-Aufnahmen beobachtet. Als eine weitere Möglichkeit zur Beschreibung von Gefüge- und Porenstrukturen wurden Kugelpackungen modelliert und deren Strukturdaten ermittelt. Mit einem an der HTWK entwickelten stochastisch-heuristischen Algorithmus lassen sich wirklichkeitsnahe 3D-Gefügemodelle aus kugelförmigen Feststoffpartikeln generieren. Die Kornverteilung ist dabei wählbar. Für die erstellten Gefügemodelle kann der vollständige Porengraph einschließlich der Porengrößen und Engstellen ermittelt und ausgelesen werden. Ein an der BAM entwickelter und durch die BUW erweiterter Säulenversuch unter Verwendung systematisch veränderter Korngemische von natürlichen Gesteinskörnungen und Glaskugeln ergab weitere Aufschlüsse über die strukturbildenden Fraktionen des Korngerüstes. Die Perkolationstheorie ist eine moderne wahrscheinlichkeitstheoretische Methode, um Fluss- und Transportvorgänge innerhalb poröser Medien zu simulieren. Über Porennetzwerkmodelle werden die komplexen Fließwege in der Porenstruktur vereinfacht abgebildet. An der BUW wurde ein 3D-Bond-Perkolationsmodell auf einem simplen kubischen Gitter realisiert, in dem die Gitterknoten die Poren und die Gitterstäbe die Porenengstellen repräsentieren. Lokale und globale Strukturveränderungen infolge Partikeltransports werden über die Analyse von Porenräumen beschrieben. Mit diesem Perkolationsmodell können Aussagen zur lokalen und globalen Strukturveränderung durch Partikeltransport in definierten Bodenvolumen abgeleitet werden. Die hergeleiteten Zusammenhänge zu den suffosiven Materialtransportbedingungen mit der Perkolationstheorie sind für homogene, isotrope und selbstähnliche Erdstoffgefüge gültig.

Die Anwendung von Geokunststoffen in Wasserbauprojekten bietet zwar verschiedene wirtschaftliche und technische Vorteile, wurde jedoch kürzlich in Frage gestellt, da sich diese Materialien während ihrer Lebensdauer verschlechtern und langfristig gefährliche Auswirkungen auf die aquatische Umwelt haben können, insbesondere als Ursprung von Kunststoffabfällen oder als Quelle / Senke für Chemikalien wie Weichmacher und Stabilisatoren, die bei der Herstellung von Geokunststoffen verwendet werden, um deren Leistung zu verbessern.

Aufgrund solcher Zusätze in Kunststoffen landet etwa die Hälfte von Sb am Ende der Lebensdauer in der Verbrennung fester Siedlungsabfälle und folglich in relevanten Mengen in der erzeugten Bodenasche. Bei Kontakt mit Wasser ist die anfängliche Auslaugbarkeit gering, da Antimonat mit Ca2+ schwerlösliche Verbindungen bilden. Nach der Carnonatisierung der Verbrennungsasche (IBA) während der fortschreitenden Alterung nimmt der pH-Wert in den Sickerwasser ab. Mit abnehmender Ca-Konzentration im Eluat ändert sich das Lösungsgleichgewicht und Antimonate lösen sich auf. In Deutschland ist beabsichtigt, Sb in IBA mit der geplanten Umsetzung der sogenannten Mantelverordnung (MantelVO, die Bestimmungen zur Verwertung von Mineralabfällen enthält) in naher Zukunft zu regulieren. Die im Entwurf festgelegten Grenzwerte können für IBA kritisch sein und stellen daher ein Risiko für die Verwendung der Mineralfraktion von IBA in den gut etablierten Recyclingwegen dar.

Their potential to leach into water during the aging process was investigated using column percolation tests. Aging-related changes on the surface of the material were characterised by IR measurements indicating oxidation reactions with the formation of new adsorption bands (C=O, C–O and OH), especially in the case of photooxidative aging. These findings were confirmed by the identification of leachable organic compounds. Leaching of total organic carbon, Cl, Ca, Cu and Zn is clearly affected by changes due to aging, and their release is increased after photooxidative aging. In general, exposure to photooxidative conditions shows a greater influence on aging and thus on leaching and seems to be the more important mechanism for the aging of microplastic in the environment. Comparison with the total content of inorganic species revealed that, for most elements, less than 3% of the total content is released after 2000 h of photooxidative aging.

Selbst in einem reichen Land wie Australien werden unbehandelte Abfälle einfach deponiert. Im Rahmen der Travelling Conference, einer vom Bundesministerium für Bildung und Forschung (BMBF) geförderten Vortragsreihe, besuchten Fachleute die Länder Südkorea, Vietnam und Australien, um mit Experten vor Ort Fragestellungen aus der Abfallwirtschaft zu diskutieren. Zu den Schwerpunktthemen zählte die Steigerung der Ressourceneffizienz im Spannungsfeld von ökonomischen und umweltpolitischen Interessen. Eine Frage war beispielsweise die Bewertung der Umweltverträglichkeit von mineralischen Abfällen, wenn diese als Ersatzbaustoffe eingesetzt werden. In diesem Beitrag werden Ähnlichkeiten und Unterschiede bei der Entsorgung von Siedlungsabfällen, beim Recycling und bei der Bewertung der Umweltverträglichkeit der Wiederverwertung von Abfällen in den drei besuchten Ländern im Vergleich zu Deutschland aufgezeigt. Dabei ist man sich in Deutschland und den drei besuchten Ländern einig, dass die Abfallbeseitigung auf Deponien ohne Rückgewinnung von Ressourcen oder Energie die schlechteste Abfallentsorgungsoption ist. Einigkeit besteht auch darin, dass die Ziele einer nachhaltigen Abfallwirtschaft der Schutz der menschlichen Gesundheit und der Umwelt sowie die Schonung von Ressourcen sind. In allen drei Ländern werden große Mengen an mineralischen Abfällen erzeugt, die bei Nachweis der Umweltverträglichkeit einen Teil von natürlichem Sand und Kies für die Bauindustrie ersetzen könnten. Ähnlich wie in Deutschland werden recycelte Abfälle im Tiefbau jedoch nur in geringem Maße eingesetzt. Gründe dafür sind fehlende Behandlungsanlagen für mineralische Abfälle und Bedenken im Hinblick auf die Umweltverträglichkeit.

T1 - The Guideline Series VDI 4800 Resource Efficiency: An Approach for Increasing Resource Efficiency with Aim of Conservation of Natural Resources in the Industrial Sector N2 - In 2011, the Association of German Engineers (VDI) started working on a set of guidelines towards increased resource efficiency. These guidelines represent a framework that defines resource efficiency and outlines considerations for the producing industry. A special guideline for SMEs is included as well as guidelines on methodologies for evaluating resource use indicators, such as the cumulative raw material demand of products and production systems. Resource efficiency, defined here as the relationship between a specific benefit or use and the natural resources that need to be spent or consumed to attain this benefit or use. It can be evaluated by defining a function which expresses the specific benefit and quantifies the resource requirements through a set of indicators (use of raw materials, energy, water, land and ecosystem services including sinks). The results from this also depend on the system boundary parameters and the allocation rules for by-products and waste treatment options. Optimising resource use is possible at all stages of a product’s or production system’s life cycle chain (raw material extraction, production and manufacturing, use and consumption, and the end-of-life stage). VDI guidelines are widely accepted across Germany’s industrial sector and therefore represent an important means of mainstreaming resource efficiency in this target area. As well as providing a methodological framework, the guidelines describe strategies and measures towards increasing resource efficiency, and they enable industrial producers and service providers to identify potential areas of improvement. The full article presents an overview of the methodology and contents of these guidelines and discusses their impact in achieving absolute reductions in the industrial use of natural resources.

This paper elucidates evaluation methods for waste treatment processes for the comparison of ecological and economic aspects such as material flow analysis, statistical entropy analysis, energetic and exergetic assessment, cumulative energy demand, and life cycle assessment.The work is based on the VDI guideline 3925. A comparison of two thermal waste treatment plants with different process designs and energy recovery systems was performed with the described evaluation methods. The results are mainly influenced by the type of energy recovery, where the waste-to-energy plant providing district heat and process steam emerged to be beneficial in most aspects. Material recovery options from waste incineration were evaluated according to sustainability targets, such as saving of resources and environmental protection.

T1 - Resource recovery from incineration bottom ash: Basics, concepts, principles N2 - Waste-to-energy (WtE) is one of the leading technologies for municipal solid waste (MSW) treatment in Europe. According to Eurostat data, in 2015, 27 % of MSW was utilized in WtE plants, which represents more than 80 million tons per year. Therefore, the European annual production of incineration bottom ash (IBA) is about 20 million tons, as it is about 25 wt% of input MSW. In the European List of Waste, IBA is listed as mirror entry (i.e. waste materials which should be classified as either non-hazardous or hazardous, depending on its hazardous properties and/or content of hazardous substances) under codes 19 01 11 and 19 01 12. Recent trends indicate that WtE allows, apart from utilization of the energy content of waste, also the recovery of various valuable components. Hence, WtE can be included in the key technologies that can put the circular economy concept into practice. Secondary raw materials in the case of WtE are solid residues, especially IBA, as it is a secondary source, particularly of ferrous metals (Fe) and non-ferrous metals (NF) and glass. Moreover, the residual mineral fraction can be used for various applications in the construction industry, i.e. as aggregates substitute for bound or unbound applications, in cement manufacturing or, as indicated by recent research, also in more sophisticated applications, e.g. for ceramics production. Recovery of these metals can also cause huge greenhouse gas savings. Alone in Europe, metal recovery from IBA reduces greenhouse gas emissions by approximately 3.2 million tonnes of CO2 equivalent.

Storms influence leads to deformation of some of the protection structures and cause the release of geotextiles onto the beach. Fragments of geotextile migrate along the shore, experiencing additional degradation and destruction down to macro-, meso-, and micro-particles. During October 2017 - March 2018, the Baltic Sea shore along the Sambia Peninsula (Kaliningrad Oblast of the Russian Federation) was monitored to establish the contamination of sandy beaches by geotextiles that had degraded. Several local sources of pollution of beaches by geosynthetic materials were established.

Due to changes in elastic properties during long-term use in the open air, as well as due to its huge size, this structure can become a non-negligible source of microplastic pollution in the Baltic Sea. Weather conditions affected the functioning of the structure, so it was assessed that geosynthetic materials used in this outdoor (open-air) operation in coastal protection structures degraded over time. Samples taken at points with different ambient conditions (groundwater outlet; arid places; exposure to the direct sun; grass cover; under landslide) were tested on crystallinity and strain at break. Tests showed a 39–85% loss of elasticity of the polymer filaments after 3 years of use under natural conditions. Specimens exposed to sunlight are less elastic and more prone to fail, but not as much as samples taken from shaded areas in the grass and under the landslide, which were the most brittle.

To demonstrate the matrix tolerance of the method, several PFAS contaminated soil and sludge samples as well as selected consumer product samples (textiles, food contact paper and permanent baking sheet) were investigated. µ-XRF mapping allows for a unique element-specific visualisation at the sample surface and enables localisation of fluorine containing compounds to a depth of 1 µm. Manually selected fluorine rich spots were subsequently analysed via fluorine K-edge µ-XANES spectroscopy. To support spectral interpretation with respect to inorganic and organic chemical distribution and compound class determination, linear combination (LC) fitting was applied to all recorded µ-XANES spectra. Complementarily, solvent extracts of all samples were target-analysed via LC-MS/MS spectrometry. The detected PFAS sum values range from 20 to 1136 µg/kg dry weight (dw). All environmentally exposed samples revealed higher concentration of PFAS with a chain length >C8 (e.g. 580 µg/kg dw PFOS for Soil1), whereas the consumer product samples showed a more uniform distribution with regard to chain lengths from C4 to C8. Independent from quantified PFAS amounts via target analysis, µ-XRF mapping combined with µ-XANES spectroscopy was successfully applied to detect both point-specific concentration maxima and evenly distributed surface coatings of fluorinated organic contaminants in the corresponding samples.

Im Falle der per- und polyfluorierten alkylierten Substanzen (PFAS) stellen sich Wissenschaftler*innen weltweit seit über zehn Jahren diese Frage. Neben der etablierten Methodik der Einzelstoffanalytik (engl. target analytic) existieren Summenparameteranalysen zur Quantifizierung organisch gebundener fluorierter Verbindungen in Umweltmedien und Konsumprodukten. An der Bundesanstalt für Materialforschung und -prüfung (BAM) beschäftigen wir uns mit der Weiterentwicklung von Summenparametermethoden am Beispiel von PFAS-belasteten Umweltkompartimenten wie Böden, Klärschlämmen und Gewässerproben sowie PFAS-haltigen Konsumgütern. In diesem Beitrag stellen wir zwei ausgewählte Fallbeispiele vor und diskutieren die Vor- und Nachteile der Methoden im Vergleich zur Einzelstoffanalytik.

The EOF values for ten sewage sludges from Germany and Switzerland range from 154 to 7209 mg kg−1. For thermal treated sewage sludge and struvite the EOF were lower with values up to 121 mg kg−1. Moreover, the application of PFAS targeted and suspect screening analysis of selected sewage sludge samples showed that only a small part of the EOF sum parameter values can be explained by the usually screened legacy PFAS. The hitherto unknown part of EOF sum parameter contains also fluorinated pesticides, pharmaceutical and aromatic compounds. Because these partly fluorinated compounds can degrade to (ultra-)short PFAS in wastewater treatment plants they should be considered as significant sources of organic fluorine in the environment. The combined results of sum parameter analysis and suspect screening reveal the need to update current regulations, such as the German fertilizer ordinance, to focus not solely on a few selected PFAS such as perfluorooctane sulfonic acid (PFOS) and perfluorooctanoic acid (PFOA) but consider an additional sum parameter approach as a more holistic alternative. Moreover, diffusion gradient in thin-films (DGT) passive samplers were utilized as an alternative simplified extraction method for PFAS in solid wastewater-based fertilizers and subsequently quantified via combustion ion chromatography. However, the DGT method was less sensitive and only comparable to the EOF values of the fertilizers in samples with >150 mg kg−1, because of different diffusion properties for various PFAS, but also kinetic exchange limitations.

N2 - In Deutschland fallen aktuell pro Jahr über 5 Mio. Tonnen Hausmüllverbrennungs-aschen (HMVA) an. Eine Verwertung dieser Aschen und Schlacken ist in Deutschland möglich und findet überwiegend im Deponiebau statt. Für die Verwertung sind in der Ersatzbaustoffverordnung Eluatgrenzwerte für Schwermetalle und einige andere Parameter vorgesehen. Der Umgang mit HMVA könnte durch eine Einstufung als gefährlicher Abfall erschwert werden. Maßgeblich für die Einstufung eines Abfalls als gefährlich oder ungefährlich sind die gefahrenrelevanten Eigenschaften HP 1 bis HP 15 nach Anhang III der Richtlinie 2008/98/EG über Abfälle mit dort festgelegten Konzentrationsgrenzen. Für HMVA ist im Wesentlichen nur der Parameter HP 14 (Ökotoxizität) von Bedeutung. Dafür sind entscheidend die Gehalte an chemischen Verbindungen mit den Gefahrenhinweiscodes (hazard statement code, HSC) H400, H410, H411, H412 und H413. Eine detaillierte Diskussion zu den übrigen Gefahreneigenschaften bei HMVA findet sich in der Literatur. Die Einstufung als gefährlicher Abfall erfolgt nach festgelegten Rechenregeln. Die BAM bearbeitet ein durch das UBA gefördertes Forschungsprojekt zur Erfassung und Bewertung von Analysedaten zu Aschen und Schlacken aus Abfallverbrennungsanlagen. Die Ergebnisse des Vorhabens sollen bei der Weiterentwicklung des vorhandenen Konzeptes für eine bundeseinheitlichen Untersuchung und abfallrechtlichen Einordnung von Aschen und Schlacken aus deutschen Abfallverbrennungsanlagen unterstützend herangezogen werden. Im Vortrag werden Verfahren zur quantitativen Bestimmung der einstufungsrelevanten Verbindungen vorgestellt: 1.) der Praxisleitfaden von ITAD und IGAM, 2.) Methode basierend auf der Bioverfügbarkeit und 3.) Methode basierend auf Speziierungsanalyse.

Entry 19 01 11* describes a waste material containing hazardous substances. It was shown that only the hazardous property HP14 (ecotoxic) is of relevance for the classification. If substances with the hazard statement code (HSC) H400, H410, H411, H412 and H413 are present in incineration bottom ash (IBA) above certain level the waste is classified as hazardous, otherwise it is non-hazardous (in this case 19 01 12). It was further shown that only Cu, Zn and Pb compounds have an impact on the classification using a summation rule: 100xΣ c(H410) + 10xΣ c(H411) + Σ c(H412). Limit value is 25 percent. It is obvious that H410 substances have the highest impact. Therefore, the knowledge of the elemental composition of IBA is not sufficient because the content of distinct chemical compounds (with the respective molecular weight) is needed. When the exact speciation is not known a worst-case approach has to be applied. A practical guideline for the estimation of HP14 was developed based on the definition of 4 substance groups: 1. Metals and alloys, 2. Water-soluble substances, 3. Oxides and carbonates and 4. Substances not soluble in weak acids. In substance group 1 only fine Zn powder has the HSC H410. Water-soluble substances are assumed to be H410 substances. Their concentrations are, however, regularly below the cut-off value of 0.1 %. The amount of substance group 3 is estimated by a selective extraction with maleic acid. According to the worst-case approach it is assumed that CuCO3xCu(OH)2 and ZnO represent the respective Cu and Zn species in IBA because these substances have the highest stochiometric factor. Even with this worst-case approach results from operators of IBA treatment plant showed that the limit value of 25 % is not exceeded. The requirements for utilization of IBA in Germany are defined in the Secondary Building Materials Decree (Ersatzbaustoffverordnung EBV) which was set into force in August 2023. Leaching methods (batch test or column test) with a liquid-to-solid ratio of 2 l/kg are applied. IBA fulfills the requirements for class HMVA-2. Actually, even a classification of IBA as hazardous (i.e 19 01 11*) would not affect utilization but handling and transport.

Therefore, a hydrolysis-based extraction method was further developed, which accounts for the addition of hydrolyzable covalently bound polyfluoroalkylated side-chain polymers (SFPs) to the extractable organic fluorine portion of the mass balance proposed as "hydrolyzable organically bound fluorine" (HOF). To test this hypothesis, the method was applied to 39 different consumer products containing fluoropolymers or monomeric PFAS taken from four different categories: outdoor textiles, paper packaging, carpeting, and permanent baking sheets. We also evaluated the method's efficiency by extracting four synthesized fluorotelomer polyacrylate reference compounds. The total fluorine (TF) and extractable organically bound fluorine (EOF) values were measured through CIC using established protocols. The TF values ranged from sub-ppb to %-levels, depending on the compound class. All samples showed results for hydrolyzed organofluorine (HOF) between 0.03 and 76.3 μg/g, while most EOF values were lower (
