Less carbon, more circularity: Trimet gives aluminium recycling a cleaner makeover

Trimet has reduced direct carbon dioxide (CO2) emissions at its aluminium recycling plant in Gelsenkirchen, Germany, by 25 per cent, saving approximately 4,000 tonnes annually through a transition to hydrogen-rich coke oven gas.
