Material Use and Recycling — Case Studies
2009
Défi, on recycle, learning through example
Since 2008, small and medium-sized businesses in the Nicolet-Yamaska and Bécancour regional county municipalities have benefited from a free coaching service by taking part in the Défi, on recyle (Recycling Challenge) program. The initiative enables them to develop their own waste management plan with a view to achieving the ICI ON RECYCLE! designation from Recyc-Québec.

Recycling and reuse of waste – two major priorities
For many years, all four plants of Alcoa Canada Primary Metals have been certified under ICI ON RECYCLE! (Here we recycle!). This program, operated by the government corporation of RECYC-QUÉBEC, recognizes corporations, businesses and institutions that achieve certain reduction, reuse, recovery and recycling objectives for containers, packaging, materials or products, and that promote reuse with a view to resource conservation.

Extending pot life to reduce waste
A series of initiatives at the Deschambault Smelter resulted in the development of a new technology to extend the life cycle of pots. This innovation, which has also been adopted in Australia, Iceland and the United States, received a 2008 Alcoa Impact Award for North America.

The Deschambault Smelter’s facilities at the Port of Trois-Rivières
The main raw materials used by the Deschambault Smelter – alumina, coke and petroleum – arrive by ship at the Port of Trois-Rivières. Storage capacity is 75,000 metric tons for alumina and 20,000 metric tons for coke and petroleum.

A new life for by-products
The Bécancour smelter has always thought that the waste it generates can be reused. This belief has been held since plant start-up, as was apparent from its early purchase of a building to store process wastes until a new use or recycling solutions could be found.

Optimization and reuse in the Electrolysis sector
As part of a project to optimize the electrolysis process, the Deschambault aluminum smelter removed almost 300 metric tons of carbon dust from its pots. Carbon dust, which is considered a hazardous waste, is formed when small quantities of carbon fall into the electrolysis bath when anodes are being replaced.
