Alcoa Company introduced a $51-million venture to extend the manufacturing capability at its Mosjøen smelter in Norway by 14,000 metric tons per 12 months (mtpy). Alcoa’s Mosjøen location presently has a nameplate capability of 200,000 mtpy, and the funding is predicted to extend that capability to 214,000 mtpy by the top of 2026.
Amperage to the positioning’s two potlines shall be elevated by way of improved electrical infrastructure, together with the set up of latest excessive voltage cabling and switching gear. The deliberate funding may even enhance the positioning’s current anode manufacturing processes.
We proceed to construct on our optimistic historical past of accelerating the capabilities and output of our current belongings by way of course of enhancements and capital investments. Mosjøen is already a top-performing asset in Alcoa’s international system, and this funding displays its operational excellence, the dedication of our workers, and the robust help from our many purchasers and neighborhood stakeholders.
—John Slaven, Alcoa’s Govt Vice President and Chief Operations Officer
The Mosjøen smelter is totally powered by renewable power and produces rolling ingots and foundry alloys, together with metallic for Alcoa’s Sustana line (earlier submit), which is probably the most complete providing of low-carbon merchandise within the aluminum business.
In that model household, Mosjøen produces EcoLum aluminum, which affords lower than 4.0 metric tons of carbon dioxide equal emissions (scope 1 and a couple of) from bauxite mining, alumina refining, and aluminum smelting and casting. It additionally produces EcoDura aluminum, which incorporates a minimum of 50% recycled content material.
Induction furnace. Alcoa additionally not too long ago introduced that its Mosjøen facility is now working a state-of-the-art induction furnace that makes use of renewable power to soften and recycle scrap aluminum.
The venture stems from a collaboration between Alcoa and MMG Aluminium, a German-based metals buying and selling firm that provides Mosjøen with clear aluminum chips and shavings which were compressed into briquettes.
Induction Furnace Operator Serban Baci inspects the aluminum inspects aluminum alloy briquettes that had been as soon as scrap and can quickly be sustainably recycled.
The induction furnace effectively melts these briquettes after which pours out the recycled aluminum for mixing with the smelter’s low-carbon aluminum and numerous alloying supplies, relying on the end-use purposes.
Most vegetation internationally remelt scrap utilizing furnaces powered by pure fuel burners situated on the partitions and roofs, radiating warmth onto materials positioned within the heart. Mosjøen’s induction furnace, nonetheless, runs on electrical energy sourced from wind and hydropower and makes use of alternating present that runs by way of a resisting coil, creating warmth. That warmth melts the scrap and any impurities are eliminated earlier than pure aluminum is poured off by way of the furnace’s tilting mechanism.
By melting aluminum by way of renewable-powered induction, roughly 4,400 metric tons of carbon dioxide emissions per 12 months are prevented by not utilizing a standard furnace with pure fuel.
Alcoa’s induction furnace was Alcoa’s single largest return-seeking capital venture in 2021, and it was in-built a document 10 months.
Up to now three years, Alcoa Company has invested roughly $50 million in sustaining and return-seeking capital initiatives on the location.
