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.
