摘　　要：应用基于熵权密切值的生命周期评价方法对纸浆、淀粉基塑料、发泡塑料、非发泡塑料、掺合型、微生物合成型6种一次性餐盒材料进行比较分析.基于熵权的量化分析表明:6种材料的资源环境性能差异主要体现在生产环节,生产过程中污染物排放与资源消耗的差异大,特别是生产过程中的水耗、木材消耗以及BOD、有机氯的排放差异大;6种材料中,以微生物合成型(聚乳酸为例)材料和掺合型(淀粉植物纤维发泡材料)在生产和处置环节的资源环境负荷为小,纸浆型材料的环境友好性劣于塑料,为6种材料中资源环境最不友好的材料.这一比较结果有助于消费者重新审视自身的消费行为.Life cycle assessment combining entropy-weighted osculating value method was em- ployed to evaluate environmental friendly properties of six binds of disposable fast food containers, i.e. pulp, starch-based plastics, foam plastic, non-foam plastic, microbial-blended material and microbial-synthesis material. The quantitative analysis based on entropy weight showed that： diver- gence among these six materials were mainly in production process expressed as pollutant emission and resource consumption, especially water consumption, wood consumption, and BOD and or- ganochlorine discharge. Microbial-blended and microbial-synthesis materials, were of the least re- source and environment load, pulp, however, whose environmental friendly was worse than plas- tics were the worst one among the six materials. Our result may be a help for consumer to reconsider their consuming behavior.
