Rio Tinto, Geocycle Canada and Lafarge Canada partner for circular economy project
MONTREAL, Oct. 16, 2020 /CNW Telbec/ - Rio Tinto, Geocycle Canada and leading construction materials company Lafarge Canada are working together to reuse waste from the aluminium smelting process to make cement. Geocycle Canada, a Lafarge Canada subsidiary, and Rio Tinto 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 will produce on average one million tonnes of cement a year at its facilities in Bath, Ontario, using Alextra as an alternative to raw materials such as alumina and silica, which are commonly refined or mined for use in the manufacturing of cement. Geocycle Canada senior manager Travis Smith explains: "As a global leader in building materials, we are committed to living up to the responsibility of helping to create a zero waste future. In order to achieve this goal, we need progressive partners such as Rio Tinto, and we look forward to what the future holds as we work to reduce our demand on virgin materials and deliver sustainable products."
