Aurubis EIB copper expansion loan strengthens Europe’s critical copper supply

Aurubis

The Aurubis EIB copper expansion loan marks a major step in Europe’s critical raw materials strategy. The €200mn investment loan from the European Investment Bank (EIB) will fund capacity growth at Aurubis sites in Bulgaria and Germany. As a result, the Aurubis EIB copper expansion loan directly targets higher refined copper output and more recycled copper flows into EU industry.

The Aurubis EIB copper expansion loan is also the first EIB metals-sector financing under the bank’s new raw materials strategy. In March, the EIB committed to lend around €2bn a year to critical raw materials projects. These include extraction, processing, recycling and substitution technologies across the energy transition value chain. Therefore, the Aurubis EIB copper expansion loan serves as an early flagship for this new mandate.

EIB backs primary and secondary copper growth at Pirdop and Hamburg

Aurubis will use the EIB loan to expand both primary and secondary copper capacity. At Pirdop in Bulgaria, the company is investing €120mn to enlarge its tank-house. This expansion will lift refined copper cathode capacity by 50pc to 340,000 t/yr. Commissioning is planned for fiscal year 2025-26, adding meaningful volumes to Europe’s copper pool.

At the same time, Aurubis will invest €190mn in its Hamburg smelter and refinery complex. The project will enable an extra 30,000 t/yr of recycled copper scrap processing, alongside more internal smelting intermediates. Therefore, the Aurubis EIB copper expansion loan supports both mined copper and circular copper streams. This dual focus directly aligns with EU priorities on recycling, resource efficiency and lower embedded emissions.

These expansions will further cement Aurubis’ position as Europe’s largest copper producer. Increased output from Pirdop and Hamburg should improve regional security of supply. That security is critical as copper demand rises for grid upgrades, renewables, electric vehicles, artificial intelligence and data centre infrastructure.

Copper market vulnerability drives EU support for Aurubis

Recent market dynamics underline why the Aurubis EIB copper expansion loan matters for Europe. Earlier this year, a huge influx of global copper flowed into the US. End-users and traders stockpiled metal ahead of expected US copper import tariffs that never materialised. However, the diversion exposed how quickly European copper availability can tighten when trade flows shift.

Europe’s vulnerability stems from its heavy dependence on imported copper concentrates and refined metal. Any tariff scare, logistics disruption or geopolitical shock can pull units away from the Atlantic basin. Therefore, building more regional smelting, refining and recycling capacity has become a strategic priority. The Aurubis EIB copper expansion loan is a concrete step toward that goal.

By boosting both primary cathode output and recycled copper processing, Aurubis supports a more resilient supply base. Meanwhile, EIB-backed capital lowers financing costs and signals strong policy alignment. Over time, this combination could help stabilise European copper premia and reduce exposure to external shocks.

The Metalnomist Commentary

Aurubis’ deal with the EIB shows how copper is moving to the centre of Europe’s industrial and energy transition policy. The mix of primary capacity growth and scrap-based expansion reflects a realistic view of future copper constraints. Market participants should watch how quickly the new tank-house and Hamburg upgrades translate into additional cathode and scrap-processing volumes, especially if trade tensions divert metal again.
