Natural fibres have been commonly utilized to reinforced materials for many years. Recently due to advantages of natural fibres such as low cost, high physical and mechanical resistance, plastic-composite materials are produced by mixing various proportions. In addition, in plastic composites, natural fibres including agricultural wastes (wheat straw, rice straw, hemp fibre, shells of various dry fruits, etc.) are used. In this study, polymer composites are manufactured using waste nutshell flour as filler and polypropylene (PP) as polymer matrix. The nutshell–PP composites are manufactured via extrusion and compression methods. The final products are tested to determine their tensile, flexural, impact strength properties as well as some physical features such as thickness swelling and water absorptions. The best results are demonstrated by obtained composites containing 30% nutshell flour. In addition, composites, which are produced with nutshell, provide the values of ASTM D6662 standard. The data collected in our country, which wastes a large portion of nutshell, allow for the evaluation of the production of polymer composites. The incorporation of nutshell flour feasible to produce plastic composites when appropriate formulations are used. As a result, hazelnut shell, which is considered as agricultural waste, can be utilized in polymer composite production.
