Project
In order to meet the latest standards in ecological materials management, Frei Fördertechnik AG realised one of the most modern soil washing plants in Europe in Péry-La Heutte following intensive process engineering planning. This fulfils the highest demands of the circular economy by recycling contaminated mineral construction waste and sludge. This innovative plant recycles 200,000 tonnes of contaminated mineral construction waste every year.
The materials delivered (contaminated excavation, overburden and excavated material) mainly correspond to landfill types B, D ballistic material or E, D. The processing steps include crushing in two crushing stages, material washing using a turbo washer and attrition, sand classification in horizontal classifiers for an optimised screening curve, metal separation (FE/NE) with neodymium magnets and eddy current separators, light material sorting using three jigging machines, gravel classification on classifying screens with air suspension, glass sorting using sensor sorters as well as water treatment and filtration.
The aggregates cleaned at the plant meet the standards for concrete aggregates and can be reused as primary or secondary raw materials.
