摘要
目的以聚乙烯(PE)淋膜纸杯、聚乳酸(PLA)淋膜纸杯和丙烯酸聚合物涂层纸杯3种一次性纸杯为研究对象,评估和比较不同纸杯对人体健康和环境的影响,为纸杯企业与行业提供参考。方法采用生命周期评价(LCA)方法,使用eFootprint软件进行一次性纸杯生产阶段的生命周期评价,包括目标与范围确定、清单分析、生命周期影响评价及解释、数据质量评估4个部分。结果在纸杯用纸的定量均为210 g/m^(2)和淋膜(涂层)层数均为一层的情况下,PE淋膜纸杯、PLA淋膜纸杯和丙烯酸聚合物涂层纸杯生产的分别排放1839、2077、1826 kg CO_(2)eq.的温室气体,8.88、10.75、8.63 kg SO_(2) eq.影响酸化的气体和物质,2.93、3.23和2.93 kg(PO_(4))^(3−)eq.影响富营养化的物质。结论综合来看,丙烯酸聚合物涂层纸杯生产过程对环境更为友好。
The work aims to assess and compare the effects of different paper cups on human health and environment with three kinds of paper cups,including PLA filmed,PE filmed and acrylic polymer coated ones,as object of study,so as to provide references for paper cup enterprises and industry.The live cycle assessment of paper cups,including objec-tive/scope determination,check list analysis,life cycle impact assessment/interpretation,and data quality assessment,was conducted with LCA method and software eFootprint.When the grammage of the paper cup was up to 210 g/m^(2)and only one layer was filmed or coated,the paper cups filmed or coated with PE,PLA and acrylic polymer emitted 1839,2077 and 1826 kg CO_(2)eq.of greenhouse gases,8.88,10.75 and 8.63 kg SO_(2) eq.of gases and substances affecting acidification,and 2.93,3.23 and 2.93 kg(PO_(4))^(3−)eq.of substances affecting eutrophication,respectively.In general,the production process of acrylic polymer coated paper cups is more environmentally friendly.
