Leaching behavior of soil-like materials, granular waste and construction products - Selected research results
- The presentation will summarize German regulations on the reuse of contaminated soil-like materials (excavated soil, dredged sediments, mining residues, urban soils etc.). Leaching tests as available tools for the assessment of environmental compatibility are discussed. First results of a currently running project on the monitoring of such materials with a focus on PAH are presented.
A study on the leaching behavior of MSWI bottom ash fractions produced by an innovative wet processing technology using laboratory scale lysimeters will be presented in a second part.
The application of scrap tire granules as infill for synthetic turf and within elastic support layers of outdoor sports surfaces leads to the release of contaminants and transfer to soil and groundwater. The development of a special leaching procedure for synthetic sports surfaces and subsequent modelling of contaminant transfer to groundwater is presented in a third part of the presentation.
