LaFarge Canada tests burning tyres

Canada: 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.
