2 Agenda UPgrade an introduction Recycling potentials Case study UPgrading strategies Barrier analysis Prospecting the Urban Mine (ProSUM) 2

3 Integrierte Ansätze zur Rückgewinnung von Spurenmetallen und zur Verbesserung der Wertschöpfung aus Elektro- und Elektronikaltgeräten Improved valorization and integrated recovery of trace metals in Waste Electronic and Electric Equipment (WEEE) Project duration: Aug 2012-Jul

4 Project goals Enabling a circular economy for relevant materials in electric & electronic equipment Increasing valorization for critical metals with low recycling rates Theoretical Recycling potential Total content of elements Technical Recycling potential Element content that can be recovered with existing technologies and infrastructure considering thermodynamic limits Environmental Recycling potential Element content that can be recovered with less environmental impact compared to primary production Economical Recycling potential Element content that can be recovered under current market conditions 4

5 Upgrading pre-processing of WEEE Recycling-oriented characterization Treatment trials Analysis of design trends Recycling potential Barrier analysis Process development & optimization Stakeholder dialogue 5

14 ProSUM Prospecting Secondary raw materials in the Urban mine and Mining waste Establish an EU wide information network; Build the architecture for secondary raw materials intelligence through an inventory of CRMs for: E-waste (WEEE) Batteries (BAT) End-of-Life Vehicles (ELV) Mining wastes Provide a European Urban Mine Knowledge Data Platform (EU-UMKDP) interoperable with the M4EU EU-MKDP Funding The project is funded by the European Union ( 3.051m) and the Swiss Government ( 0.63m). The project will be delivered over three years, ending in December This project has received funding from the European Union s Horizon 2020 research and innovation programme under grant agreement No

15 Background European minerals databases & intelligence networks Development of a sustainable exploitation scheme for Europe's REE ore deposits Development of solutions for sustainable deep sea mining Nano-particle products from new mineral resources from Europe European Geological Data Infrastructure EUMINET European Mineral Information Network MICA Mineral Intelligence Capacity Analysis 15

16 The ProSUM project ProSUM Information Network Includes researchers, the recycling industry, producer compliance schemes, producers, public authorities, national geological surveys and other EU project partners. Shares best practice, benchmarks, and opportunities to increase data harmonisation and cooperation. Information Network launch on April 25, 2015 in Brussels (82 attendees) Join the Information Network: 16

17 Conclusions Electronic products are a relevant end-demand sector for various elements classified as critical To enable a circular economy requires more than technology development Current barriers for recovery need to be well understood At the long-term we need a knowledge base about the urban mine to enable investment planning and policy decision 17
