In 1989, the Alumax group took on the challenge of building the Deschambault Smelter in an area whose fragility and value made environmental performance a top priority. The smelter started up in 1992, and had reached its full annual production capacity of 215,000 metric tons by 1993. Its technical performance has been an international benchmark ever since and, thanks to continuous improvements in equipment, processes and work methods, the smelter’s production capacity has been increased to 260,000 metric tons.


Its forward-looking management approach positions employees as the drivers of the smelter’s current results and future growth. Among its many achievements, it received the Hélène-Vandale award from the Comité sectoriel de main-d’oeuvre de la métallurgie du Québec for its commitment to providing women with access to non-traditional careers and trades. The Deschambault Smelter’s environmental performance is a worldwide benchmark in water management (thanks to its zero wastewater discharge system), as well as in fluoride collection and treatment processes. The smelter’s equally strong commitment to energy efficiency has been rewarded with a number of distinctions, including awards from the Canadian Industry Program for Energy Conservation and the Association québécoise pour la maîtrise de l’énergie.


The Deschambault Smelter is a Distinction member, the highest level, of Hydro-Québec’s Energy Saver’s Circle, a network of energy efficiency leaders.
