abb partners with boliden to reduce carbon footprint of its industrial products

abb is working with boliden, the swedish mining and smelting company, to build a strategic co-operation to use low carbon footprint copper in its electromagnetic stirring (ems) equipment and high-efficiency electric motors. the aim is to reduce greenhouse gas (ghg) emissions while driving the transition to a more circular economy.

the partnership with boliden forms an integral part of abb’s strategic ambition to reduce the environmental impact of raw materials used in its products by replacing them with lower carbon alternatives. apart from using recycled copper, abb has committed to increase the use of recycled electric steel (e-steel) and recycled aluminum. the move is also an important step in closing the circularity loop that has already seen abb designing its motors to be up to 98 percent recyclable, with the remaining two percent of materials available to be incinerated for heat recovery. recycling copper, aluminum and steel offers energy savings of between 75 and 95 percent compared to virgin production.

the co-operation includes abb placing the first order for boliden’s certified recycled copper through finnish metals manufacturing specialist luvata. hollow conductor wire made from the material will be used in abb’s ems products for both steel and aluminum manufacturing.

furthermore, as of 2023, abb will purchase boliden’s low-carbon and recycled copper to cover the demand for its ie5 ultra-premium efficiency synrm and e-mobility motors produced in europe. the two companies have also signed a memorandum of understanding that will see abb supporting boliden in identifying inefficient low-voltage motors across its operating units. these motors can then be replaced with high efficiency motors within abb’s take back upcycling framework, with the old motors recycled to provide raw material for boliden’s recycled copper.

copper is a vital material for manufacturing industrial electrical equipment, but its production is energy intensive. to address this, boliden has developed low-carbon copper that is mined using fossil-free energy and also produces copper using secondary raw material from recycled products. the carbon footprint of these products is 65 percent lower than the industry average. a typical 75-kilowatt (kw) motor weighing 650 kg might include 80 kg of copper. using boliden’s copper saves approximately 200 kg of co₂ emissions for every one of these motors manufactured. each stirrer has up to 2,700 kg of copper, saving up to 6,700 kg of co2 per stirrer.
