Lafarge Canada starts low carbon fuels study at Exshaw plant
12 January 2018Canada: 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.
Lafarge Canada to test burning tyres at its Brookfield plant
30 September 2016Canada: Lafarge Canada has started a partnership with Dalhousie University researcher Mark Gibson to test tyre-derived fuel on an industrial scale at the Brookfield cement plant in Nova Scotia. Working under a Natural Sciences and Engineering Research Council of Canada (NSERC) Discovery Grant, this initiative will research the adoption of low carbon fuels in the cement industry. The research will continue the partnership between Lafarge Canada and Dalhousie's Faculty of Engineering.
"My students and I are very pleased to see this work enter the real world. Based on our research, we expect to see significant reductions in greenhouse gas emissions from the Brookfield cement plant and thereby help Nova Scotia move one step closer to a low carbon economy," said Gibson. He added that the use of tires will also reduce NOx emissions. In 2015, Gibson and his team published a report entitled ‘Use of scrap tyres as an alternative fuel source at the Lafarge cement kiln, Brookfield, Nova Scotia.’
Due to different initiatives including previous work with Dalhousie's Faculty of Engineering, the Brookfield plant has substituted alternative fuels for conventional ones by using front-end burner injection in its kiln. The plant is expected to reach a substitution rate of up to 30% by the end of 2016. Following the test using tyres the cement producer expects to use 15% of its fuel requirements from 450,000 tyres per year, or just under half the amount of tyres generated in Nova Scotia. The project proposal will be explained in further detail at a Public Meeting planned for 20 October 2016 in Brookfield.
