A Study on Waste Paper Reinforced Recycled Polypropylene Biocomposite

Abstract:

The growing global request to make green materials nowadays expresses in reducing environmental problems and obtaining biomaterials with high-performed properties. Aside from being carbon neutral, the use of biomass for obtaining green materials contributes to energy security and climate change mitigation. The aim of the work was to fabricate and study a recycled polypropylene-based composite filled with recycled waste paper obtained by the acid hydrolysis of de-inked newsprint. It has been found that, with increasing the content of the recycled paper microparticles in the bio-composite, its mechanical and wetting properties deteriorated. The presence of maleic anhydride grafted polypropylene as a compatibilizer increased the homogeneity of the structure of the bio-composite, which improved its mechanical properties and decreased its ability to be wetted with water.
