Abstract: We can link the requirements of sustainable soil quality with the goal of waste utilisation by integrating modern environmental scientific knowledge and technological innovation into a risk based management system. As examples, two case studies are introduced in this article. The area of the former lead and zinc sulphide ore mine in Gyöngyösoroszi, Hungary is heavily polluted with toxic metals. The combination of phytostabilisation and chemical stabilisation using wastes as amendment was applied to various metal sulphides containing mine wastes.. The fly ashes were able to reduce the water soluble Cd and Zn content by more than 99% and the acetate extractable content by 49%. The high toxicity of the mine waste was reduced, and healthy vegetation developed on the previously barren surface. The waste deposit at Gyál, Hungary is covered by low quality waste soils. Soil amendment experiments with wastes as soil additives demonstrated that addition of a mixture of wastes to the soil can result in a fertile cultivation medium.
