Hazelnut husk is widely available as a biowaste in the northeast of Turkey. In this study, biocomposites were manufactured using hazelnut husk, polypropylene, and coupling agent. Density, thickness swelling, water absorption, modulus of rupture, modulus of elasticity, tensile strength, tensile modulus, and elongation at break tests were carried out to determine its performance properties. The results obtained in this study indicated that the performance properties of the biocomposites manufactured from hazelnut husk could be comparable to neat PP composites. The biowaste-loading level positively affected the modulus properties of the biocomposites. It could be concluded that the hazelnut husk could be used as an alternative raw material to produce new biocomposites so that biowaste could be recycled. It can also help sustainable protection of nature.
