During the recycling of waste paper from private households different fractions containing plastics and polluted paper fibers are received. Those polluted fibers can not be recycled in the common paper manufacturing process or for energy recovery like in waste incinerating plants due to economic reasons.
Current research at the Institute for Polymer Materials and Plastics Engineering at Clausthal University of Technology evaluated the use of this waste paper recyclate as a substitution for natural fibers as fillers and reinforcements in polypropylene. Special attention was given to the mechanical properties of the composites. Additionally the influence of maleic anhydride grafted polypropylene (MAPP) as an adhesive was investigated.
