TY - CONF A1 - Kalbe, Ute A1 - Schatten, Rene A1 - Szuppa, Tony T1 - Monitoring of soil-like materials for potential reuse N2 - Paragraphs 6 to 8 of the proposed amendment to the German Federal Soil Protection and Contaminated Sites Ordinance contain new requirements regarding the application of soil-like material outside of a rootable soil layer. For example, it is intended to enable reusing of soil-like materials containing regulated substances in concentrations between the single and double precautionary values (PV), provided that the limit values for the eluate are complied with. The aim of a running project (funding code UFOPLAN 3716 74 203 0, German Federal Environmental Agency) is to fill data deficits for soil-like materials which meet the above-mentioned criteria to promote circular economy and conservation of natural resources. Different soil-like materials of various origin (for example dredged material, banquet peeling material, urban and meadow soils) are considered with a special focus on PAHs. A major challenge in sample acquisition is the relatively narrow target range of the PAH content between 3 and 6 mg/kg dm considering a high measurement uncertainty at this concentration level. The contents of PAHs, heavy metals and other inorganic elements in solid matter are determined following established standards. In addition, the soil-like materials are characterized concerning particle size, pH, conductivity, SOM, TOC and carbonate content. To determine the eluate concentration, column tests according to DIN 19528 and batch tests according to DIN 19529 at a liquid/solid ratio (L/S) of 2 l/kg and 10 l/kg are performed comparatively. The results show that the new requirements of the planned amendment to the Federal Soil Protection and Contaminated Sites Ordinance certainly opens additional possibilities for reuse of soil-like materials. Even most soil-like materials within 2-3 x PV comply with the eluate value for PAH (0.2 μg/l) both in the batch test and in the column test at L/S 2 l/kg. Selected inorganic substances lead to similar evaluations. Therefore, the application of such soil-like materials outside of rootable soil layers would be possible. Previously, those materials were often used for landfill construction. In the future, a utilization in the adjacent environment by backfilling, recultivation, renaturation, composting or landscaping would be conceivable.

T1 - Waste, Evaluation Methods T2 - Ullmann's Encyclopedia of Industrial Chemistry N2 - It is difficult to decide which waste management system fulfills best predefined sustainability goals such as maximum materials and energy recovery, least environmental impact, and lowest societal cost. Such decisions are based on many parameters. However, several evaluation methods exist with different scope and output, and the application of one or more evaluation methods provides an objective comparison of alternatives.

T1 - Sustainable remediation methods for metals and radionuclides T2 - Encyclopedia of Sustainability Science and Technology 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.
