| contents | <p>This deliverable has been developed within Work Package 7 (WP7) of RESilEX (Resilient Enhancement for the Silicon Industry Leveraging the European Matrix), entitled “Multi-faceted Impact Assessment & EU Policy Recommendations”, under Task 7.2, which focuses on Comparative Environmental Sustainability Assessment. The main objective of RESilEX is to improve the resilience and the sustainability of the EU’s silicon value chain. To this end, several innovative technologies are being developed, going from critical raw material’s recovery, silicon production, photovoltaic solar cell and module manufacturing to recycling of solar panels or the integration of silicon in battery technology replacing graphite. The main objective of Task 7.2 is to evaluate the environmental performance of various innovative technologies that are being developed and studied in the other work packages of the RESilEX project. To this end, life cycle assessment (LCA) will be used to enable the identification of the hotspots of each innovative technology in order to steer process development towards a lower environmental impact. Subsequently, the LCA results will be compared with conventional processes (reference), indicating the potential benefits of the new technologies. Finally, the contribution to circular economy and potential critical raw material savings will be investigated in this task. The first step towards assessing the environmental sustainability of the innovative technologies is to define the systems under study and create flowsheets for each technology and reference cases. This forms the basis for preparing the life cycle inventory and constructing mass and energy balances. These quantitative data are required for the LCA and circularity and criticality assessment.<br>According to the project's progress, it has not yet been possible to fully assess the environmental impact of each innovative technology. However, each process has been thoroughly described in this deliverable. A reference case and the scenarios to be studied have been selected for each innovative technology. A functional unit is also selected, needed as the reference for comparison. In other words, the goal and scope of each innovation technology is defined, including the basked of products for many systems, enabling a fair comparison between the innovation technology and the reference case selected.<br>An overview of the status of data collection is provided with the sources selected in each case, as well as a plan for the next steps. Additionally, a life cycle impact assessment (LCIA) has been conducted for two innovation technologies, the eco-design of both solar cells and modules, providing a detailed illustration of the results obtained. These first results indicate a promising result of the innovations in terms of environmental impact. However, results might differ among impact categories, highlighting the importance of a broad environmental sustainability assessment. </p> |
