The utilization of rubberwood waste as a reinforcement in polymer composites could decrease environmental impacts from the waste, as well as increase value of the waste material. Moreover, rubberwood waste reinforced thermoplastics also offer advantages including biodegradability, renewable character, absence of associated health hazards, low density, low cost, and low equipment wear during their processing (Ashori et al., 2013; Nourbakhsh and Ashori, 2010), when compared to inorganic or synthetic fillers (Yemele et al., 2013).
