It is prior knowledge that EDTA-based soil-washing efficiently removes Pb and other toxic metals from soil. However, more than 20-years of research by many groups worldwide has not resulted in a feasible solution for EDTA recycling, for the problem of vast amounts of generated waste waters and for toxic emission due to EDTA environmental persistence. ReSoil® resolves all these problems. It is an internationally patented, cost-efficient, soil preserving and environmentally safe remediation technology.
