Verfahren und Vorrichtung zur trockenen Auftrennung von Sammelmüll mit Verpackungsabfällen

摘要

The invention relates to a method for the dry separation of unsorted garbage that contains packaging waste, said packaging waste including plastics of various polymer groups. The inventive method comprises the following steps: separating the materials on the basis of differences in size; separating the materials on the basis of differences in grain shape, grain size and/or specific weight; separating the materials on the basis of differences in their magnetic properties; separating the materials on the basis of differences in their electric properties; and separating 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 mass flow that contains non-recyclable remaining garbage and plastic articles. The plastic articles are collectively removed from the mass flow as a mixed plastic fraction and said mixed plastic fraction is selectively separated into substantially polymer-specific fractions using polymer-specific separation methods. The invention also relates to a device for carrying out the inventive method.
