PYROGENESIS COMPLETES PLASMA TORCH SYSTEM BUILD FOR CONSTELLIUM, COMMENCES DELIVERY AND INSTALLATION PHASE

PyroGenesis Inc. has completed the manufacturing of the plasma torch system for its client Constellium, one of the world's largest aluminum transformation and recycling companies. Delivery of the various system components to one of Constellium's European facilities is under way and will continue over the next five weeks. An engineering team from PyroGenesis will be on site to receive the shipments and start installation, with commissioning scheduled during Q2 2026.

As previously announced (see press release dated Aug. 5, 2025), PyroGenesis signed an industrial implementation contract with Constellium for the sale of plasma torch technology and related peripheral components for use in a Constellium aluminum remelting furnace, with commissioning targeted for Q1 2026. This followed a previous announcement (see press release dated April 10, 2024) detailing a collaboration agreement, whereby Constellium stated its intention to use PyroGenesis plasma torches as potential replacement heating sources in Constellium's aluminum cast houses. This initiative remains exploratory and is conducted at demonstrator scale as part of Constellium's broader research and development activities to explore alternatives to traditional natural gas burners.

With today's announcement, PyroGenesis confirms that: (i) the initial plasma torch system has been completed; (ii) large component delivery by container ship has already begun; and (iii) installation activities will commence as the various components arrive over the next five weeks.

Project highlights

Purpose:  Constellium to explore PyroGenesis's all-electric plasma torches, among other alternative technologies, to implement cleaner, more sustainable methods for high-temperature industrial heating, reducing carbon emissions and enhancing energy efficiency in aluminum processing

Scope:  installation and commissioning of proprietary plasma technology in an industrial-scale demonstrator furnace at Constellium's casthouse

Timeline:  shipping is under way; installation activities will commence as components arrive in Europe, with commissioning expected during Q2 2026

Strategic impact:  supports Constellium's road map to reduce GHG (greenhouse gas) emissions

"Today's announcement sets the stage for the first use of PyroGenesis's plasma system in a factory-scale aluminum remelting furnace. Constellium's aluminum research centre performs some of the most sophisticated large-scale research and testing for their industrial clients in highly demanding sectors such as aerospace and defence. The metal produced from this project is expected to be incorporated into these clients' commercial applications," said P. Peter Pascali, president and chief executive officer of PyroGenesis. "The transition toward electrified industrial processes must be grounded in both performance and economic viability. This is a balance that our plasma torch technology is uniquely positioned to deliver. By pro-actively pursuing cleaner and more efficient energy solutions, Constellium is setting the tone for the industry. Together, we are advancing the electrification of an energy-demanding area of aluminum manufacturing."

Industry and market context

Primary aluminum production is an energy-intensive process that is typically produced using electricity; secondary aluminum production, using recycled aluminum, requires 95 per cent less energy to produce.

According to Pathways to Decarbonization: A North American Aluminum Roadmap, aluminum production emissions must decline by 24 per cent by 2030, 63 per cent by 2040 and 92 per cent by 2050 compared with 2021 levels to meet net-zero targets, highlighting the urgent need for cleaner technologies across both primary production and secondary remelting.

Aspects of secondary aluminum production that use fossil fuels (natural gas), such as the remelting of scrap metal, can potentially utilize alternative energy sources such as plasma. Global aluminum demand is projected to rise nearly 40 per cent by 2030 and up to 80 per cent by 2050, driven by growth in automotive, aerospace and packaging.

Plasma-based electrification offers a cleaner, scalable alternative to traditional fuel-based heating, aligning with industrial energy transition and decarbonization mandates.
