Awareness towards enviromental impact had stimulated the interest for converting polystyrene from waste materials into value added-products so called from 'waste to wealth'. Recycling is one of the common and easy process for waste management. However, polystyrene foams have recycling limitations because it contains flame retardant material. In this invention, we overcome this problem by using a new technique of recycling whereby converting the waste polystyrene to a new resin. After extensive studies, the new resin applied as matrix material reinforces with oil palm empty fruit bunch (EFB) fiber to produce new composite materials. Excellent adhesion between the polystyrene resin and the EFB fiber had exhibit promising results on tensile, flexural and impact properties. In addition, the new composite materials are low weight, low water uptake and customizable as can be applied in furniture.
