Abstract
In a method and an arrangement for treating a light fraction that is produced during the treatment of plastic-rich waste that is low in metal, at least the following steps are carried out consecutively: the light fraction is stressed by percussion and/or bashing, the light fraction is classified into at least two light fraction classes, at least one light fraction class is separated into at least one light material fraction and a heavy material fraction, at least one light material fraction is cleaned. The cleaning of the light material fraction (fibrous material), obtained after the separation, provides a very clean initial substance to be obtained, resulting in clearly improved material recycling and energy recovery.

A method for conditioning a light fraction high in fibers, produced during conditioning of low metal scrap high in plastics, comprising:
- after producing the light fraction high in fibers downstream from a shredder process:
- applying stresses to the light fraction by at least one of (a) impact and (b) shock;
- classifying the light fraction into at least two light fraction classes;
- separating at least one light fraction class into at least one light material fraction and a heavy material fraction;
- and
- cleaning at least the light material fraction.
A system for conditioning a light fraction high in fibers, produced during conditioning of low metal scrap high in plastics, comprising:
- downstream from a process adapted to produce the light fraction high in fibers downstream from a shredder process:
- a device adapted to apply stresses to the light fraction by at least one of (a) impact and (b) shock;
- a classification device adapted to classify the light fraction into at least two light fraction classes;
- a separation device adapted to separate at least one light fraction class into at least one light material fraction and a heavy material fraction;
- and
- cleaning device adapted to clean at least the light material fraction.
