Boliden and Tretau power low-carbon electrification
Boliden and magnet wire supplier Tretau are strengthening the electrification value chain by combining responsibly produced Low Carbon Copper with high-performance magnet wire solutions. By aligning upstream metal production with technological innovation, they enable more efficient and lower-carbon electric machines and systems.
Connecting responsible production with innovation
Boliden and Tretau are working together to support the growing demand for electrification. By combining responsibly produced copper with advanced magnet wire technology, the collaboration addresses both material sourcing and performance requirements in electric systems.
“Electrification requires not only more metals, but metals produced responsibly and used efficiently. By combining our Low Carbon Copper with advanced magnet wire technology, we create value for customers and customer’s customers who wants to reduce their carbon footprint. Without compromising on performance”, Daniel Asplund, Manager Sales Copper, Boliden, says.
Boliden’s Low Carbon Copper, part of the company’s Green Transition Metals portfolio, has a carbon footprint of 1.5 kg CO₂e per kilogram of copper, compared with a global average of approximately 4.0 kg CO₂e per kilogram. Produced using copper from Boliden’s own mines, the product supports customers in reducing emissions across the value chain, including Scope 3.
Reducing emissions in magnet wire production
Tretau complements this with solvent free, high performance magnet wire, engineered to meet the growing demands of electrification. Its DryCycle® technology eliminates solvents from the insulation process, enabling resource-efficient manufacturing while maintaining thermal, electrical, and mechanical performance in electric machines.
The approach is based on a shorter, more energy-efficient coating process, resulting in a structurally lower carbon footprint per kilogram of magnet wire. The impact is most significant at the insulation and transformation stage, where emissions are, on average, 65% lower than those associated with legacy coating technologies, with variations primarily driven by technical specifications.
“Our mission is to revolutionize the wire industry through sustainable high performance solutions. When upstream responsible metal production meets downstream innovation, it accelerates electrification and delivers real climate benefits.”, says Francesco Taiariol, Co founder and CEO of Tretau.
Supporting the transition to electrification
Together, Boliden and Tretau contribute to a more resource-efficient and lower-carbon electrification value chain. By combining material performance with reduced climate impact, the collaboration supports the development of electric vehicles, machinery and systems.
