European recycling projects are targeting printed circuit boards and electronic scrap as sources of copper, precious metals and critical raw materials, with the Netherlands emerging as a location for specialised processing and metallurgical recovery facilities.
The European Commission awarded Strategic Project status in October to CRITICAL.’s proposed Urban Mining Factory for printed circuit boards in the Netherlands. The planned facility is designed to process 15,000 tonnes of low-grade waste printed circuit boards annually, recovering copper, aluminium, nickel, silver, gold, palladium, platinum and tin.
Printed circuit boards targeted for metal recovery
Printed circuit boards contain mixtures of metals that can serve as secondary industrial resources. Recovering these materials at commercial scale requires processes capable of separating individual elements while controlling emissions, residues and material losses.
CRITICAL. identifies copper as a central recovered material, with additional critical metals intended for consolidation and transfer to specialist refining facilities.
This approach separates pre-processing from final metal recovery. Dedicated facilities can concentrate valuable materials before sending them to smelters or hydrometallurgical plants equipped to extract individual metals, creating an industrial chain from waste collection to refining.
Mitsubishi Materials develops complementary processing capacity
Japan’s Mitsubishi Materials is pursuing a related approach through its proposed 3ECYCLE plant in the Netherlands. The facility will use electronic scrap as its primary feedstock and recover copper and other valuable metals using technologies developed through the company’s non-ferrous smelting business.
Together, the proposed projects represent different stages of electronic waste processing, from specialised material preparation to metallurgical recovery. The Netherlands is developing several recycling operations intended to collect, sort, upgrade and refine different secondary material streams rather than relying exclusively on one large processing facility.
Recovered metals support industrial supply chains
Copper recovered from printed circuit boards can return to electrical applications, while nickel and other metals can be redirected into industrial supply chains. Gold, silver, palladium and platinum provide additional sources of value that can support the economics of processing feedstock containing lower-value materials.
Domestic processing capacity also affects how much of the value embedded in European electronic waste remains within the region. Collecting scrap without sufficient refining infrastructure can leave Europe dependent on external processors for recovering its embedded metals.
Critical Raw Materials Act supports project development
Europe’s raw-material security depends not only on access to mineral deposits but also on ownership of refining technology, metallurgical infrastructure and reliable supplies of recyclable feedstock.
The Critical Raw Materials Act (CRMA) provides a framework intended to address these dependencies. Strategic Project status can facilitate project development and permitting and improve access to relevant financing instruments. The commercial viability of urban-mining facilities will depend on securing consistent feedstock, managing energy costs, achieving efficient metal recovery and establishing reliable buyers for the recovered materials.
