Abstract
A process is disclosed for disaggregating waste materials which contain at least partially reusable elements, mainly metals, plastics and cardboard. The waste materials are stirred in water by mechanical forces, large pieces, in particular plastic pieces, are coarsely crushed and soluble elements, in particular cardboard, are dissolved. The metallic elements are separated from the suspension as heavy materials, the remaining coarse solids, in particular plastics, are mechanically separated from the suspension, and the suspended fine solids are separated from the suspension by dewatering.
