Our approach to waste management is to reduce waste generation wherever possible. When waste is generated, we attempt to reuse the waste or make it practical for others to reuse. A regional committee made up of representatives from each Alcoa smelter in Québec identifies and shares solutions to decrease landfilling.
Various residues are generated by a smelter, with the most significant quantities consisting of spent pot linings and foundry dross.
In 2009, Alcoa Inc. set a target to reduce landfilling by 75% before the end of 2020 from baseline year 2005, excluding spent potlining.
