Abstract
Indonesia is one of the biggest plastic waste production in the world. The government targets to reach 20% for recycling plastic waste in 2019. One alternative to manage plastic waste is using pyrolysis to produce fuel. Pyrolysis is used to degrade the plastic long chain of polymer molecules into smaller molecules. All type of plastic except polyvinyl chloride (PVC) were used in this study to produce fuel. For the purpose, experiment factorial design was used for the optimisation plastic type, residence time, and temperature to maximise the yield of liquid products of the pyrolysis process. In this study 2k factorial design was used for each factor. The result shows that the pyrolysis process used is able to produce diesel like fuel in low temperature.
