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.
