In the last three decades, the increased use of plastics is rapidly becoming a global environmental issue, resulting in growing landfills, pollution of surrounding atmosphere, and possible greenhouse effect. The automotive industry, as a major demander of plastic materials, is starting to take responsibility on sustainable actions. Japan, as the world's top tier car manufacturing and dealing country, has been taking attempts to the proper dealings of used auto-plastic. This research aims to find out current situation of auto-plastic recycling industry after these attempts. Furthermore, this research compares pros and cons of each treatment and methods under treatment environmentally as well as economically from the point of recycling operators using life cycle assessment. Bumper is chosen as the target to represent auto-plastic because of their homogeneity of composition and relatively large share of weight among all auto-plastic parts. The result shows that material recycling amount is decreasing along with recent promotion demonstration. Top reason is that material recycling even reduces carbon emissions, costs far more than energy recovery, and that subsidy is given to energy recovery but not material recycling worsens the situation. Besides that, lack of cooperation between stakeholders on the demand of secondary plastic is impeding material recycling. Also, better scheme on how to separate auto-plastic and what kind would be separated should be noticed by the policymaker.
