Until now, the data on CRMs has been produced by a variety of actors and lies scattered in different databases, formats and reports which makes it difficult to compare or aggregate. The ProSUM project - Latin for ‘I am useful’ - aims at producing the EU Urban Mine Knowledge Data Platform (EU-UMKDP) providing user friendly, seamless access to data and intelligence on mineral resources from extraction to end of life products. The project will be addressed to a wide range of end-users, including the recycling industry, producers and producer compliance schemes, and policy makers.
