Canada: Lafarge Canada, University of Calgary, Queen’s University, and Pembina Institute have started a study on the environmental benefits of introducing lower carbon fuels at the Exshaw Cement Plant in Alberta. Eight lower carbon fuels will be researched, including construction renovation and demolition waste, non-recyclable plastic, carpets and textiles, shingles, treated wood products, wood products, rubber and tyre-derived fuels. These sources of fuel have been successfully used at other LafargeHolcim cement plants in Canada.
“Lab simulations, environmental studies, economics and logistics reviews are already underway. All research will be finalised by December 2019 with regular updates provided to the neighbouring communities via a Public Advisory Committee,” said Jim Bachmann, the plant manager of Exshaw .
Additional research by the partners will measure the environmental components associated with the sourcing, processing and full-scale commercial operation of each lower carbon fuel compared to fossil fuels. The project will also measure the benefits of diverting materials from landfills and determine optimal points in the cement manufacturing process to inject each fuel.
In addition to Lafarge’s support, research funding is being provided by Alberta Innovates, Ontario Centres of Excellence, Emissions Reduction Alberta and the Natural Sciences and Engineering Research Council of Canada. It includes research by Millennium EMS Solutions Ltd., Geocycle, and WSP Global Inc.
As part of its 2030 Sustainability Plan, LafargeHolcim aims to replace 30 - 50% of fossil fuel use at its Canadian cement plants with lower carbon fuels by 2020.
