Method and device for the dry separation of unsorted garbage that contains packaging waste

摘要

The invention relates to a method for the dry separation of unsorted garbage that contains packaging waste consisting of plastic materials of various polymer groupings that includes the following steps: separation of the materials on the basis of differences in size; separation of the materials on the basis of differences in grain shape, grain size and/or specific weight; separation of the materials on the basis of differences in their magnetic properties; separation of the materials on the basis of differences in their electric properties; and separation of the materials on the basis of differences in their spectroscopic properties. Every separation step is carried out at least once and the separation of components of the unsorted garbage results in a remaining material throughput that contains non-recyclable residual waste and plastic articles from which the plastic articles are collectively removed in the form of a mixed plastic fraction and said mixed plastic fraction is selectively separated into essentially polymer-specific fractions using polymer-specific separation methods. The invention also relates to a device for the implementation of the inventive method.
