Title
(EN) PROCESS FOR SPLITTING RESIDUES TO RECOVER SECONDARY RAW MATERIALS
(FR) PROCEDE DE SEPARATION DE RESIDUS POUR OBTENIR DES MATIERES PREMIERES DE RECUPERATION
Abstract
(EN)
In this process for reducing so far unused residues from tailings, soiled plastics from "yellow waste", strainings from sewage plants, rubbish from dumps and sand residues to obtain and recycle secondary raw materials, said wastes are subjected to a repeated cycle of wet and dry sieving, separation, sorting and classification. The clean secondary raw materials obtained are preferably conditioned in stages in an aerobic environment and, except for difficult materials, taken directly to biological, material or raw material processing plants. Conditioning the secondary raw materials also permits long intermediate storage owing to the slight degree of rotting and stink. The low investment costs make it possible to set up small plants for regional waste economies while still offering economic advantages over competing technologies. The system can be operated without subsequent deposition or mass incineration for the residue processing involving about a sixth of the partial mass flow rate of mixed plastics, composites and other materials. Residues can be made into building materials. Fine strainings are not given any prior dry mechanical treatment.
