Abstract

Abstract Silk is a distinctive and significant category of natural structural protein fiber. With a remarkable structure and versatility, silk has emerged as a topic of scientific study perennially because of its chemical, physical and biological properties. Meanwhile, in order to have an omnifaceted understanding of silk, the environmental performance of silk production is also worthy of attention. With the concern of global warming, efforts are increasingly focused on understanding and addressing carbon emission in the life cycle of silk products. However, the majority of current studies give priority to the carbon emission of either just one or a few stages of silk products’ life cycle, or to a specific type of silk product. On the basis of a review of literature on the life cycle assessment of silk products, this study presents a full-scale review of the quantification of the carbon emission and carbon neutrality of cocoon acquisition, industrial production of silk products, distribution, consumption, and recycling. The analysis revealed that the carbon sequestration by photosynthesis at the stage of cocoon acquisition could not be ignored. It is of importance to establish complete and unified system boundaries when quantifying carbon emissions in the industrial production of silk products. Reasonable models of washing times and washing modes are needed to assess carbon emissions in the domestic laundry of silk products. At the end of life phase of silk products, the positive impact on carbon emission in the phase of silk recycling is noteworthy. This study will help interested scholars, manufacturers and consumers to gain an in-depth understanding of the carbon emissions and carbon neutrality of silk products, and it is also of great value for exploring new production processes for reducing carbon emissions of silk products.
丝绸产品生命周期碳排放与碳中和研究综述
摘要丝绸是一类独特而重要的天然结构蛋白纤维。丝绸具有显著的结构和多功能性,由于其化学、物理和生物特性,一直是科学研究的主题。同时,为了对丝绸有一个全方位的了解,丝绸生产的环境性能也值得关注。随着全球变暖的担忧,人们越来越关注了解和解决丝绸产品生命周期中的碳排放问题。然而,目前的大多数研究都优先考虑丝绸产品生命周期的一个或几个阶段的碳排放,或特定类型的丝绸产品。本研究在回顾丝绸产品生命周期评估文献的基础上,全面回顾了蚕茧收购、丝绸产品工业生产、分销、消费和回收的碳排放量化和碳中和。分析表明,采茧阶段光合作用固碳作用不容忽视。在对丝绸制品工业生产中的碳排放进行量化时,建立完整统一的系统边界具有重要意义。需要合理的洗涤时间和洗涤模式模型来评估国内丝绸产品洗涤过程中的碳排放。在丝绸产品的生命末期,丝绸回收阶段对碳排放的积极影响值得注意。本研究将有助于感兴趣的学者、制造商和消费者深入了解丝绸产品的碳排放和碳中和,对探索减少丝绸产品碳排放的新生产工艺也具有重要价值。
