| 中文摘要: |
| 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/m2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1 839、2 077、1 826 kg CO2 eq.的温室气体，8.88、10.75、8.63 kg SO2 eq.影响酸化的气体和物质，2.93、3.23和2.93 kg (PO4)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。 |
| 英文摘要: |
| 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 objective/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/m2 and only one layer was filmed or coated, the paper cups filmed or coated with PE, PLA and acrylic polymer emitted 1 839, 2 077 and 1 826 kg CO2 eq. of greenhouse gases, 8.88, 10.75 and 8.63 kg SO2 eq. of gases and substances affecting acidification, and 2.93, 3.23 and 2.93 kg (PO4)3− eq. of substances affecting eutrophication, respectively. In general, the production process of acrylic polymer coated paper cups is more environmentally friendly. |
