This paper reviews a number of Malaysian agricultural wastes such as cocoa pod husk (CPH),
betel nut husk (BNH), and coffee hulls/husks (CH) with potential for use as reinforcement in
polymer composites. Some notable advantages exhibited by these agricultural wastes as
reinforcement in polymer composites, and their current utilization were discussed. Recent
attempts by several workers in utilizing CPH, BNH, and CH were also reviewed and elaborated
to find out the effect and further potential of incorporating these agro-wastes fibers in polymer
composites. Challenges such as compounding difficulties, storage issues and lack in deep
finding regarding these types of fibers are believed to be the factors that make CPH, BNH and
coffee hulls/husks fiber are still being underutilized in Malaysia
