We reduced landfilled waste (excluding spent pot lining and casthouse dross) by 7% compared to 2011, which represents a decrease of 65% compared to 2005, the reference year for Alcoa’s 2020-2030 objectives. Last year’s decrease is mainly attributable to the recycling of used refractory from the ovens at the Bécancour Smelter.
Process wastes remain the primary challenge, particularly at the Baie-Comeau Söderberg plant. For all other types of waste, the Baie-Comeau, Bécancour and Deschambault smelters expect to renew the “ICI ON RECYCLE” designation they achieved in 2009.
The Bécancour Rod Plant received an honourable mention for reduction at the source during its accreditation (Performance level) in 2012.
