摘　　要：以生物质全降解450mL餐盒为例,以全生命周期评价(Life cycle assessment,LCA)方法为基础,首先建立了生物质全降解制品全生命周期评价模型,然后对制品全生命周期内资源消耗、环境质量、人类健康等环境友好性进行了量化评价,并和450mL塑料餐盒的环境友好性进行对比。结果表明:生物质全降解制品全生命周期内对资源消耗、环境质量、人类健康等影响分别为26.6mPt、6.23mPt、16mPt,而塑料制品全生命周期内的影响分别为291mPt、12.1mPt、74.1mPt,因此,生物质全降解制品具有更好的环境友好性。The environmental friendly characteristics of biomass products in a life cycle perspective was explored using LCA method. The analysis model of biomass 450 mL lunch box was established. In addition, the envi-ronmental friendly characteristics of the box, such as resource consumption, environment quality and human health,were analyzed. Finally, the results shown that the resource consumption, environment quality and human health ofbiomass products were 26. 6 mPt, 6. 23 raPt, 16 mPt, and these parameters of plastic products were 291 mPt, 12. 1mPt, 74.1 mPt. Therefore, the biomass products are more environmental friendly than plastic products.
