1. A process for the production of a composite material from textile waste derived from clothing and polyethylene film waste, comprising the following steps:
a) comminuting the textile waste derived from clothing into a comminuted textile fraction up to 15 mm in size, and comminuting the polyethylene film into a comminuted polyethylene film fraction up to 15 mm in size,
b) separating metal parts from the comminuted textile fraction, and separating metal parts and unwanted plastics from the comminuted polyethylene film fraction,
c) further comminuting the comminuted textile fraction into a further comminuted textile fraction up to 5 mm in size,
d) mixing the further comminuted textile fraction with the comminuted polyethylene film fraction, said further comminuted textile fraction constituting 10-50% of the mixture, and
e) plasticizing, homogenizing and extruding the obtained mixture in an extruder at a temperature of 170-240° C. and under a pressure of 8-15 MPa, to thereby produce a composite material.
