Supplementary data for the PhD thesis: Sustainability of bio-based plastics in a circular economy

Data files on which the studies presented in the chapters 2-5 of Linda Ritzens PhD thesis are based.<br><strong>Chapter 2</strong>: Drivers and barriers for bio-based plastics in durable applications.<strong>Chapter 3</strong>: Bio-based plastics in a circular economy: a review of recovery pathways and implications for product designTrue circularity of bio-based plastics requires efficient material recovery at end-of-life. Recovery is not only determined by material properties, but also by product design. The supplementary data of the literature review is provided in the data files.<strong>Chapter 4</strong>: Bottlenecks in establishing the environmental impact of bio-based plastics: a case study of bio-based PE and bio-based PETThe environmental impact of bio-based plastics is a highly debated topic, because the outcomes of lifecycle assessment (LCA) for bio-based plastics vary drastically. In this study, we compare the lifecycle inventories (LCI) of published bio-based plastic LCAs in order to better understand the reasons for these differences. The supplementary files contain the lifecycle inventory assessment (LCIA) outcomes as well as the supplementary information containing the full LCIs used in the study as well as figures for all ReCiPe midpoint impact categories.<strong>Chapter 5</strong>: Sustainability of bio-based polyethylene: the influence of biomass sourcing and end-of-life.The environmental impact of bio-based plastics depends on their biomass resource and recovery at end-of-life. In this study, 31 biomass sourcing scenarios and 5 end-of-life scenarios for bio-based polyethylene were studied in a LCA. The supplementary files contain the lifecycle inventory assessment (LCIA) outcomes as well as the supplementary information containing the full LCIs used in the study as well as figures for all ReCiPe midpoint impact categories.

本数据集为琳达·里岑（Linda Ritzen）博士论文第2至5章所载各项研究的基础数据文件。<br>**第2章**：生物基塑料（bio-based plastics）在耐用应用场景中的驱动因素与阻碍因素。<br>**第3章**：循环经济中的生物基塑料：回收路径综述及产品设计启示。生物基塑料的真正循环性需在其生命周期终端实现高效的材料回收。回收效果不仅取决于材料本身的属性，同时也受产品设计的影响。本研究的文献综述补充数据已收录于本数据文件中。<br>**第4章**：厘清生物基塑料环境影响的瓶颈：以生物基聚乙烯（bio-based PE）与生物基聚对苯二甲酸乙二醇酯（bio-based PET）为例。生物基塑料的环境影响是学界高度热议的议题，因为不同生命周期评估（LCA）得出的生物基塑料环境影响结果差异悬殊。本研究通过比对已发表的生物基塑料生命周期评估的生命周期清单（LCI）数据，以厘清此类差异的成因。补充文件包含生命周期影响评估（LCIA）结果，以及本研究所用的完整生命周期清单（LCI）数据与所有ReCiPe中点影响类别的可视化图表。<br>**第5章**：生物基聚乙烯的可持续性：生物质来源与报废阶段的影响。生物基塑料的环境影响取决于其所用的生物质资源与报废阶段的回收方式。本研究通过生命周期评估（LCA），分析了31种生物质来源场景与5种报废场景对生物基聚乙烯的影响。补充文件包含生命周期影响评估（LCIA）结果，以及本研究所用的完整生命周期清单（LCI）数据与所有ReCiPe中点影响类别的可视化图表。
