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.

汽车保险杠生命周期评估:基于日本报废汽车回收系统的情景分析

在过去的三年中,塑料使用量的增加正迅速成为一个全球性的环境问题,导致垃圾填埋场不断增加,周围大气受到污染,并可能产生温室效应。汽车行业作为塑料材料的主要需求者,开始承担起可持续行动的责任。日本作为世界顶级汽车制造和交易国,一直在尝试妥善处理废旧汽车塑料。本研究旨在了解经过这些尝试后汽车塑料回收行业的现状。此外,本研究从使用生命周期评估的回收运营商的角度比较了每种处理方法和处理方法在环境和经济方面的优缺点。保险杠被选为代表汽车塑料的目标,因为它们的成分均匀,并且在所有汽车塑料部件中所占的重量份额相对较大。结果表明,随着最近的推广示范,材料回收量正在减少。最重要的原因是,材料回收甚至可以减少碳排放,成本远高于能源回收,而且补贴用于能源回收而不是材料回收使情况变得更糟。除此之外,利益相关者之间在再生塑料需求方面缺乏合作也阻碍了材料的回收利用。此外,政策制定者应注意关于如何分离汽车塑料以及将分离哪种类型的更好方案。结果表明,随着最近的推广示范,材料回收量正在减少。最重要的原因是,材料回收甚至可以减少碳排放,成本远高于能源回收,而且补贴用于能源回收而不是材料回收使情况变得更糟。除此之外,利益相关者之间在再生塑料需求方面缺乏合作也阻碍了材料的回收利用。此外,政策制定者应注意关于如何分离汽车塑料以及将分离哪种类型的更好方案。结果表明,随着最近的推广示范,材料回收量正在减少。最重要的原因是,材料回收甚至可以减少碳排放,成本远高于能源回收,而且补贴用于能源回收而不是材料回收使情况变得更糟。除此之外,利益相关者之间在再生塑料需求方面缺乏合作也阻碍了材料的回收利用。此外,政策制定者应注意关于如何分离汽车塑料以及将分离哪种类型的更好方案。利益相关者之间缺乏对再生塑料需求的合作阻碍了材料的回收利用。此外,政策制定者应注意关于如何分离汽车塑料以及将分离哪种类型的更好方案。利益相关者之间缺乏对再生塑料需求的合作阻碍了材料的回收利用。此外,政策制定者应注意关于如何分离汽车塑料以及将分离哪种类型的更好方案。
