News Lafarge Canada, Geocycle Canada and Rio Tinto join forces for aluminium recycling project

Lafarge Canada, Geocycle Canada and Rio Tinto join forces for aluminium recycling project

Canada: Lafarge Canada, Geocycle Canada and Rio Tinto are working together to reuse waste from the aluminium smelting process to make cement. The three companies have developed a new product called Alextra, made from used potlining, as part of the aluminium electrolysis process that would otherwise go to landfill. Lafarge Canada plans to produce on average 1Mt/yr of cement at its plant in Bath, Ontario, using Alextra as an alternative to raw materials such as alumina and silica. The companies will also explore options to further expand the supply of Alextra from Rio Tinto’s Potlining Treatment Plant in Saguenay-Lac-St Jean to Lafarge Canada's network of cement plants.

"This partnership shows how Rio Tinto is innovating to find new ways to reuse waste, generating value from our operations and reducing their environmental footprint,” said Rio Tinto Aluminium manager valorisation and marketing Stéphane Poirier. “We have worked closely with Lafarge Canada and Geocycle Canada over the past two years to develop a product that meets their needs and look forward to building on this partnership,”
