TY - CHAP A1 - Wünsch, Christoph A1 - Simon, Franz-Georg ED - Maletz, Roman ED - Dornack, Christina ED - Ziyang, Lou T1 - The reduction of greenhouse gas emissions through the source-separated collection of household waste in Germany N2 - The production of secondary materials from waste materials requires, in most cases, significantly lower energy amounts than the primary material production of raw materials. 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.

However, leaching of chloride, sulfate and potentially hazardous heavy metals from MSWSI-BA into the environment may cause problems in utilization of it in civil engineering. 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. While concentrations of chloride, sulfate and the majority of the heavy metals started to decrease rapidly with progressive liquid-to-solid ratio (L/S), the ecotoxic hazardous elements antimony (Sb) and vanadium (V) behaved differently. To unravel these unusual release behaviors and the oxyanion-formation of Sb and V we will apply HERFD-XANES spectroscopy to analyze their chemical state.

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.

A1 - Borca, C. A1 - Simon, Franz-Georg T1 - Levels of per- and polyfluoroalkyl substances (PFAS) in various wastewater-derived fertilizers – analytical investigations from different perspectives N2 - Solid wastewater-based fertilizers were screened for per- and polyfluoroalkyl substances (PFAS) by the extractable organic fluorine (EOF) sum parameter method. 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.

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 - 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.

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.

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.
