一次性塑料水杯与涂层纸杯的生命周期评价与分析

Life Cycle Assessment and Analysis of Disposable Plastic Cups and Paper Cups

文章对日常使用的一次性塑料水杯与纸杯的全生命周期进行综合评价,比较两者对环境与人体健康的最终影响。采用了生命周期评价的技术路线与方法进行研究,最终得出一次性PE涂层纸杯的环境影响值大于PP塑料杯的结果。分析结果可得出纸杯在材料采用、制造、能耗等方面的缺陷导致了其环境影响值偏大,而PP塑料杯虽然在资源消耗与可降解性上存在劣势,但从全生命周期的视角上来看,却相对环境影响较小。

This paper conducted life cycle assessment（LCA） on disposable plastic cups and paper cups to compare their ultimate effects on environment and human health.The technical routes and methods of LCA were adopted and finally obtained the result that disposable PE coated paper cups have larger environmental impacts than PP plastic cup.Analysis of the results show that materials,manufacture,energy consumption of paper cups are the main reasons lead to higher environmental impact values.Although PP plastic cups have disadvantages in resources consumption and non-degradation,the environmental impact of PP cups is lower in the angle of whole life cycle.
