that one steel plant such as the Usiminas plant, with an annual production of 4.5 million tons of steel (almost 20 per cent of Brazilian steel production), emits about 3,000 tons per year. In aluminium fabrication, finally, emissions of gases and particles from smelting and re-heating furnaces pose the largest problems.

THE GNCS FACTSHEETS Mitigating Emissions from Aluminum

Emissions from Aluminum Production Primary aluminum production involves refining alumina from bauxite ore, then smelting it to extract aluminum. Smelting is through the Hall-Héroult electrolysis process, which involves running large inputs of electricity through dissolved alumina via a carbon anode. Emissions result
