Founded in 1991 as part of a strategy to boost an industrial area that was on the decline, Aluminium Dunkerque now mainly makes high-end alloy plates and ingots for the auto, transportation, and industrial packaging industries.
720 employees, €800 million in revenue, 300,000 tons of aluminum produced, exports to around ten countries… These key figures show the importance of the largest primary aluminum production site in France and one of the largest in Europe.

By committing to “producing low-carbon aluminum in France in a sustainable way in order to promote new modes of consumption and mobility, and shape a world that is more respectful of the planet and its inhabitants,” Aluminium Dunkerque is killing two birds with one stone.
The company stands out in a market led by China. This country—which accounts for 60% of global production—has contributed to a decline in metal prices by developing excess supply. The company, which is located on 65 hectares in the heart of the Grand Port Maritime de Dunkerque, contributes to France’s industrial sovereignty, which now has only two major primary aluminum production sites within its borders (in addition to numerous processing, recycling, and refining sites).
Its decarbonization strategy, which was highlighted in 2025 with the inauguration of its first recycling furnace, earned it the “Best Managed Companies” label awarded by Deloitte France and the National Bank of Canada. Its president, Guillaume de Goÿs, was also named “Best CEO in the Sustainable Metallurgy Industry 2025” by EU Business News for his innovative practices in sustainability and management. A decision-maker with whom we achieved a return on investment…
I would like to emphasize that we are an independent French company with international operations, wholly owned since 2021 by the American investment fund AIP (American Industrial Partners).
We are not the French subsidiary of an American group, but rather a fully-fledged French company. All our operations are based in France, our decision-making center is in France, and our board operates under French law.
This is quite different from the past, when many support services were scattered across Europe and elsewhere. This policy favors local employment. It has also resulted in successful financial results. Since AIP’s arrival, our EBITDA1 has increased approximately by two and a half times, even though we went through the energy crisis during this period and our production remained more or less constant.

Our core business is the production of primary aluminum from alumina, our main raw material. In our market, which covers all of Europe, we are the leading industrial site in the European Union and the third largest in Europe if we include Norway and Iceland.
Historically, our production began in 1991 with a strategic location in Dunkirk’s seaport. The main reason for this choice is the presence of the Gravelines nuclear power plant, located a couple of miles from our facilities (~2 miles). However, as we are the largest consumer of electrical energy in France on an industrial site, we needed to optimize this key area for our productivity through negotiated rates. The second key factor was access to a deep-water port since we import 550,000 tons of alumina per year by sea.

Thanks to new projects currently underway or planned for the future (SNF Floerger, Clarebout, Verkor, Prologium, XTC Orano, etc.), the port of Dunkirk expects to create 20,000 additional jobs by 2030.
🔎Recruit easily in Hauts-de-France.
A key issue for Aluminium Dunkerque, whose specific activity requires particular expertise. Given its age pyramid, the company must ensure that the skills of retiring employees are passed on, as well as recruit new employees.
To achieve this, it relies on internal training and collaborations with local vocational high schools and the Université du Littoral Côte d’Opale.
We take part as often as possible in promoting industrial trades that are part of our region’s cultural heritage. In fact, during a job dating event organized in Calais, we welcomed 500 people who submitted their resumes.
Our facilities are among the most modern in Europe in the primary aluminum manufacturing market. This result is the fruit of our shareholder’s efforts since joining the company in 2021.
We have gone from an annual investment budget of €40 million to nearly €60 million today, which represents an increase of approximately 50%. In particular, the Group has approved a major investment to support our growth. This concerns our new furnace No. 8, which alone required an €13 million investment.
Alongside our seven other furnaces, whose main function is to solidify the liquid metal we produce in primary alloys, this one is dedicated to recycling aluminum waste (see below). For us, this is a major innovation that supports our decarbonization efforts, which are central to our positioning and development.
Additional modernization work is also regularly undertaken at our site. This covers everything from the safety of our facilities and improving working conditions for staff to reducing our energy consumption.
🔎Read our article on decarbonization, an environmental challenge and a factor in competitiveness.
In 2025, Aluminium Dunkerque inaugurated its No. 8 furnace, the first of its kind at its site. This state-of-the-art facility recycles 7,000 tons of aluminum waste each year, mainly from the automotive, construction, and packaging industries and produces 20,000 tons of recycled aluminum with a low environmental impact.
The furnace uses oxy-fuel burners (running on natural gas and oxygen), which significantly reduces emissions from melting. It also has an internal industrial water recycling system, which prevents excessive water consumption. Thanks to this facility, the site avoids 25,000 tons of CO₂ and saves 96 GWh of electricity per year.
Aluminium Dunkerque received support from local and regional economic stakeholders in obtaining financial assistance. The project received support from the French government through the France 2030 program, European funding through the France Relance plan supported by the Next Generation EU program, and from ADEME. The cumulative intervention rate amounts to 15% of the total investment amount.
The European Union produces just over 1 million tons of primary aluminum, while consuming five times that amount. It therefore imports a significant amount from outside the EU, which raises questions about France’s and the EU’s industrial sovereignty, as they consider this metal to be strategic for the ecological transition and for our sovereignty.
However, in order to continue producing at an acceptable cost and face international competition, we need both carbon-free energy—our electricity is supplied by nuclear power—and competitive prices. This was the case under a long-term contract signed for 25 years between Péchiney and EDF in 1991.
Next, we benefited from Regulated Access to Historic Nuclear Electricity (ARENH). The main challenge facing Aluminium Dunkerque today, like all primary aluminum production plants, is to secure a competitive long-term carbon-free contract.
Our positioning embraces the future, with the aim of moving towards “green” aluminum. We have obtained the Aluminium Stewardship Initiative label developed by the international industry. This tracks all our actions in terms of our products’ sustainability.
We are also working to become part of a circular economy. This approach also allows us to demonstrate innovation in terms of R&D. We are currently working on a high-purity aluminum project and are interested in a system that would capture CO2 and transport it to storage areas via the port of Dunkirk.
We have launched an innovation initiative in the form of a consortium with a major company in the Hauts-de-France region, Fives, and two other companies in our sector: Rio Tinto and Trimet France. The goal is to develop a decarbonization solution for the aluminum industry based on CO₂ capture.
