Supplementary Data_INCREACE: Life Cycle Assessment of mechanical, dissolution and chemical recycling of WEEE plastics for added value applications

This file contains supplementary material to INCREACE Deliverable 3.3 on the Life Cycle Assessment of mechanical, dissolution and chemical recycling. The life cycle assessment (LCA) study evaluates the production of secondary plastics sourced from four plastic waste streams via three recycling pathways: mechanical recycling, dissolution recycling and chemical recycling (pyrolysis). The aim is to identify the hotspots for the most relevant environmental impact categories for each recycling pathway from cradle-to-gate and to compare these pathways with primary production for the respective polymers. In this study, the circular footprint formula (CFF) is used to capture cradle-to-grave environmental impacts. Moreover, to evaluate the influence of underlying assumptions and context on the outcomes of the study, an extensive sensitivity analysis is conducted. For consistency, reproducibility and robustness reasons, this study adheres to the ISO 14040/14044 standard, as well as the Plastics LCA Method guidelines established by Nessi et al. 2021. The report provides full transparency on the LCA scope, modelling choices and underlying assumptions. The life cycle inventory for the conducted LCA studies is based on primary data generated as part of the INCREACE project and complemented with literature data and existing datasets. All non-confidential primary data collected and applied is disclosed.
