Every year the demand for polymer materials grows. This increased demand means that the amount of waste associated with this industry is also increasing. In order to reduce the environmental impact and increase the efficiency of available resources, scientists around the world are looking for ways to use recycled polymers. As the mechanical properties of thermoplastics deteriorate with recycling, their range of applications is significantly narrowed. In order to improve the mechanical performance of recycled polymers, they are reinforced with lignocellulosic fibers. Based on multiple studies, it is known that composites based on polyolefin and lignocellulose are characterized by poor adhesion, forcing the surface modification of natural fibers before use. Chemical treatments can be based on reactions involving esterification methods like acetylation and benzylation, graft polymerization methods like treatments with triazine, isocyanates and maleic anhydride, silane coupling agents, other treatments include alkali, acrylation and acrylonitrile, permanganate, peroxide treatments and also steric acid, sodium chloride and oleoyl chloride. Surface modification of fibres reduces its moisture absorption tendency and improves their mechanical properties thereby increasing durability of the composites [1].
