The ProSUM Project aims to provide an inventory of secondary raw materials, particularly critical raw materials, arising in WEEE, end-of-life vehicles, waste batteries and mining wastes. This inventory will support industry, researchers and policy makers in their decision making processes. Through our Information Network we aim to engage with these stakeholders in the project. The project is contributing to the Strategic Implementation Plan, developed by the European Innovation Partnership on Raw Materials, by building an EU raw materials knowledge base.
