Electrical and Electronic Equipment in the EU's Urban Mine (image) ProSUM (Prospecting Secondary Raw Materials in the Urban Mine and Mining Wastes) Share Print E-Mail Caption The ProSUM project successfully harmonized all available information to map the very dynamic development of the Urban Mine over time. As illustrated in the figure, the entire stock of electronic products constitutes a considerable, and for some materials, rapidly changing Urban Mine for the years 2000 to 2020 (last 5 years projected). The figure displays for the first time the combined effect of rapidly increasing sales in numbers of electronic products, increasing miniaturization of printed circuit board volumes and products appearing (like tablets) and disappearing (like cathode ray tubes) from the market.
