As Europe Holds onto More of Its Scrap, Secondary Discounts Are Beginning to Close

Scrap that Europe used to export is increasingly being retained domestically. That is tightening availability inside the region, intensifying competition among domestic remelters for material that previously leaked to China and southeast Asia, and raising the price of clean aluminium scrap. The practical consequence is a narrowing of the discount that secondary metal has long carried against primary.

Europe has been a net exporter of aluminium scrap every year since 2002, shipping more than 1.2 million tonnes abroad in 2024 alone. That flow is now under direct policy pressure. In early December 2025 the European Commission adopted its RESourceEU Action Plan, setting firm export restrictions on permanent magnet scrap and committing to propose targeted measures on aluminium scrap. Commissioner Maros Sefcovic had signalled the direction in November 2025, describing a balanced measure rather than a blanket ban. The intent is clear: Europe is beginning to treat as a domestic resource the feedstock it spent two decades selling.

Retaining Exports Changes Who Can Bid, Not How Much Exists

Export restrictions do not create new scrap. They change who is able to bid for existing supply.

The mechanism is straightforward. European scrap has historically been priced against competition from Asian buyers, particularly Chinese traders and remelters who have consistently outbid the domestic secondary sector. By preventing that outflow, export restrictions transfer pricing power back to European remelters. They gain access to a feedstock pool that was previously leaking abroad. They then compete for it against each other, and against rising recycling demand across the continent.

That shift in competitive access is already visible in price. European scrap firmed through the opening months of 2026 as availability tightened ahead of the expected restrictions. The discount that secondary metal carries relative to primary aluminium has begun to narrow. Three structural forces are reinforcing that direction.

Energy Cost Is Where the Advantage Is Sharpest

Primary aluminium smelting requires roughly 14 to 15 MWh per tonne of metal produced. Secondary remelting requires less than 1 MWh per tonne. That gap has always existed. What has changed is its monetary value.

European industrial electricity prices have remained materially elevated since 2022. The energy cost advantage of secondary aluminium has widened in line with that. For buyers who can use secondary metal at specification, the all-in cost comparison with primary has shifted significantly and in a direction that shows no sign of reversing quickly.

Carbon pricing reinforces the same dynamic. The EU Carbon Border Adjustment Mechanism (CBAM) entered its definitive phase on 1 January 2026, attaching an explicit cost to the embodied carbon in imported primary aluminium. Secondary metal does not carry that cost. The International Aluminium Institute estimates that recycled aluminium production can require around 95 per cent less energy and generate up to 95 per cent lower emissions than primary production, depending on feedstock quality and processing route.

A third force is the low-carbon premium forming on primary itself. Lower-carbon aluminium now attracts a premium over standard P1020 in some bilateral transactions. As that premium layer develops, clean secondary material becomes a functional substitute rather than simply a discount alternative. A higher scrap price can still represent a lower total delivered cost once carbon exposure and the low-carbon premium are included.

Contamination Limits How Far Substitution Can Go

The argument for secondary aluminium rests on the assumption that it can replace primary. For a meaningful portion of scrap supply, it cannot. The reason is contamination.

Recycled aluminium loses quality each time it is melted down. With every remelt of post-consumer scrap, residual concentrations of iron, copper, and silicon increase. These elements enter the melt from mixed scrap sources, from coatings, from fasteners, and from contamination during collection. They cannot be removed economically once present. Iron above roughly 0.4 per cent limits mechanical performance in wrought alloys. Elevated copper or silicon causes the same problem. Scrap carrying these contaminants cannot be processed back into the flat-rolled or extruded products that dominate primary aluminium demand.

As a result, most post-consumer scrap flows into secondary casting alloys, typically die-casting grades such as DIN226 or EN AC-46000, rather than back into wrought product. These casting alloys tolerate higher levels of iron, copper, and silicon because they are designed for different applications. The secondary market for cast alloys is real and substantial, but it does not compete directly with primary aluminium for the same end uses.

The scrap grades that can substitute for primary are a much smaller subset: clean, well-characterised streams with documented provenance and controlled contamination levels. Beverage can scrap, automotive sheet offcuts, and clean extrusion scrap from post-industrial sources sit in this category. They are specification-grade, meaning they can re-enter wrought production without degrading alloy quality. Mixed demolition scrap, shredded post-consumer material, and commingled grades do not.

The Discount Is Closing from One End Only

That distinction matters for reading the price signal correctly. The compression in the secondary discount is real. It is not, however, happening uniformly across the market.

Export restrictions raise the price of all European scrap by reducing competition from Asian buyers. But the substitution logic, the argument that secondary should approach primary in price, applies only to the clean, specification-grade fraction. For contaminated and mixed-grade material, the discount against primary remains structural. These grades do not compete with primary aluminium. They compete with other inputs to the cast alloy market, and their price is set by casting alloy demand rather than by primary aluminium fundamentals. The CBAM and export retention do not change that.

For clean, verified, specification-grade scrap, the picture is different. Energy costs, carbon costs, supply restrictions, and green procurement requirements are all compressing the discount from the primary side. The cleanest, best-documented material could, over time, trade closer to parity with primary once carbon certificates are factored in.

Europe can retain its scrap through export controls. It can raise the carbon cost of primary through the CBAM. It can subsidise investment in recycling infrastructure. None of those measures alters the composition of the material entering the furnace. Contamination in post-consumer scrap is a function of collection systems, product design, and separation technology. It does not respond to carbon pricing.

The binding constraint on how far the secondary discount can close is not policy. It is metallurgy.

Investors and buyers watching the secondary discount should read it accordingly. The compression is meaningful and reflects genuine structural change. It is also partial and concentrated in the fraction of the market where substitution is technically possible. The rest is moving for different reasons and is unlikely to follow.
