Copper scrap (secondary copper)

European integrated copper group (SDAX: NDA, HQ Hamburg, Germany); world's largest copper recycler and one of Europe's largest copper smelters. After the September 2024 sale of its Buffalo, NY flat-rolled products site to Wieland, Aurubis exited the U.S. connector-strip market to concentrate on primary copper production, recycling, and multimetal recovery. Aurubis Hamburg remains a world-scale refinery (1M+ MT/year cathode output) and continues to supply copper cathode feedstock to strip rollers including Wieland's European facilities. Aurubis Pirdop (Bulgaria) is its primary copper smelter. The company also operates secondary smelters in Belgium (Lünen) and the UK (Swansea). Prior to divestiture, Aurubis Buffalo produced copper and copper alloy strip for electronic connectors, heat exchangers, architectural products, and electrical goods.

Largest private ferrous and non-ferrous scrap processor in Europe; operates 150+ sites across UK, Germany, Netherlands, Poland; processes ~8 MT of scrap annually; major exporter to Turkish EAF mills via Rotterdam. Private company (Philip Sheppard family).

Third-largest copper miner globally; operates Collahuasi (44% stake, Chile), Antapaccay (Peru), Alumbrera (Argentina), and Katanga (DRC). Also major copper trader. Copper production 954,400 MT in 2024.

World's largest publicly traded metal and electronics recycler; ~75% of earnings from North America; processes and exports ferrous and non-ferrous scrap from 250+ facilities across US, Australia, New Zealand, UK. Major supplier of shredded scrap to EAF steelmakers in Turkey, South Asia, and East Asia.

Umicore N.V. (Brussels; Euronext: UMI; ~$4B revenue) is a global specialty materials and recycling company whose Hoboken, Belgium precious metals refinery is a major European indium producer. Umicore recovers indium from complex lead/copper metallurgical residues and dusts at its Hoboken smelter near Antwerp — a unique secondary-metallurgy process that differs from the primary zinc-smelter byproduct route used by most producers. Umicore's indium capacity is ~50 tonnes/year, representing ~3% of global output and making Belgium a meaningful EU indium source. Umicore is also the world's leading recycler of battery materials (cobalt, lithium) and catalysts; indium recovery at Hoboken is one component of a broader complex metals recovery operation. Umicore's Hoboken plant is one of the most technically sophisticated non-ferrous secondary smelters in the world.

German family-owned copper products conglomerate (HQ Ulm, Germany), founded 1820 in Vöhringen. Dominant global supplier of copper alloy strip for electronic connector terminals — the world's largest flat-rolled copper products company by volume. In 2024 Wieland made two major moves: (1) announced a $500 million modernization/expansion of its East Alton, Illinois plant (formerly the Olin Brass flagship site, first opened 1916) to add a new hot-rolling mill and casting unit targeting EV and connector-strip growth, with Illinois contributing ~$231M in incentives; (2) acquired Aurubis's Buffalo, NY flat-rolled copper strip facility (Aug 30, 2024), absorbing ~500 employees and its specialty connector-grade strip capacity. Wieland's connector alloys portfolio includes new grades K58 and K75 (high-strength, miniaturization-ready) and the established STOL series. Also supplies ACR copper tube (Pine Hall NC), plumbing tube, and industrial copper products. In CuNiSi/Corson alloys Wieland competes directly with Japanese producers for automotive connector strip.
