The remnants of agricultural crops are produced in billions of tons and are available at low prices; only a small part of the residue is used as domestic fuel or fertilizer, as the main part burns in the field, causing air pollution and environmental hazards. Using these remnants as filler in polymer materials can solve the problem. Natural fillers from agricultural waste are replacing synthetic fibers as reinforcement in polymer composites due to their non-toxicity, low density, low cost, renewability, biodegradability and, therefore, a positive impact on the environment [1]. Despite all these positive properties, natural fiber composites suffer from a lower modulus of elasticity, lower strength, limited durability and relatively poor moisture resistance. To solve these problems and improve the basic properties of polymer composites reinforced with agricultural waste, a potential way is to combine two types of fillers. Therefore, the idea is to obtain a synergistic effect of filler properties on the overall properties of hybrid biocomposites. Thus, the main goal of this study was to assess the effect of the combination of natural bio-filler and bentonite on the physicomechanical properties of hazelnut shell/bentonite/polyethylene hybrid biocomposites.
