ABSTRACT
Production of plastic waste in Indonesia was ranked as the second producer of domestic waste that is equal to 5.4 million ton per year. Based on statistical data of domestic Indonesian waste, the amount of plastic waste that is 14% of the total waste production in Indonesia [1]. It comprises mostly plastics used in food packaging such as PET, PVC, LDPE, HDE, and PP. One of the most popular plastic packaging is plastic cup for sparkling beverages which is made from PP. Since Incineration method is not a good solution because it raises the pollutions, the only alternative left for easy disposal of this huge plastic waste is recycling to obtain value added products. Therefore, it is a promising way of use recycle PP (rPP) as matrix to obtain composite and a perfect choice due to its low cost and the resulting protection of environment. Plastic recycling is a process which basically comprises the following steps: collection, separation, cleaning and pelletizing. Adhikary [2] and Bhaskar [3] have published studies dealing with rPP composites.
