Municipal solid waste and organic waste are collected together and are temporarily stored in a deep bunker. Then the waste is pre-shredded and automatically stocked in drying boxes for 10 to 14 days. Biological processes heat the material up to 50 degrees. During the drying period the weight decreases by about 40 % because of vaporized water.
After the drying process the dried and inactive material is removed automatically out of the boxes by crane and is transported into the sorting plant by conveyor belts.
After the volume flow is divided into two parallel sorting lines, overbelt magnetic separators and eddy currents sort out all ferrous and non-ferrous metals. The remaining metal-free material flow is loaded into intermediate bunkers or directly into trailer trucks.
HTP was assigned the overall planning and the detail engineering of the RDF plant.
