Metalysis has moved to further reduce the environmental impact of its production operations with the installation of an argon recycling system expected to cut both gas consumption and associated Scope 3 emissions.
The company has contracted Gas Recovery and Recycle Limited to install its ArgonØ recycling system, which will recover and reuse exhaust argon gas generated during Metalysis’ powder production processes. Metalysis uses argon to maintain an inert atmosphere across its reactor range, protecting metal and alloy powders from contamination by oxygen, nitrogen, and hydrogen.
Once operational, the system is expected to save approximately 350 tonnes of argon per year by recycling around 95 percent of the gas used. Metalysis estimates this will translate into annual Scope 3 carbon savings of around 1,000 tonnes of CO₂, reflecting the energy required to produce and transport new argon supplies.
The ArgonØ system is designed with an energy footprint of less than 10 percent of conventional gas recycling technologies. By reducing both raw material demand and upstream energy use, the installation aligns with Metalysis’ broader strategy of embedding sustainability into its production model.
Metalysis is best known for its proprietary FFC process, which reduces metal oxides in the solid state rather than relying on energy-intensive melting. The company states that the process is already around 50 percent more energy-efficient than traditional titanium powder production routes used in additive manufacturing.
The business produces a range of critical metal and alloy powders, including capacitor-grade tantalum, aluminium-scandium alloys for semiconductor and lightweight structural applications, refractory alloys such as niobium-hafnium, and high-entropy alloys designed for extreme environments. Many of these materials are targeted at aerospace, defence, and advanced manufacturing markets where performance and sustainability requirements are increasingly linked.
For Gas Recovery and Recycle Limited, the project represents an expansion beyond its established markets in solar photovoltaics and microelectronics into advanced materials processing and manufacturing.
Metalysis views the argon recycling investment as a continuation of its focus on reducing environmental impact at both process and product level, particularly as demand for low-carbon materials grows across high-performance manufacturing sectors.
