Photodegradation is one of the main concerns when developing a plastic composite for outdoor applications. At the same time the recycling recuirements are getting more stringent demanding new use for the recycled plastic composites. In this study we have utilized stearic acid modified ZnO nanoparticles with 0.25-3.0 wt-% in polypropylene in order to decrease the photodegradation of the nanocomposites and also to preserve the UV-resistance properties of the recycled material. The results show that ZnO nanoparticles make the PP composite less opaque in visual wavelenghts than the micron particles
