Lafarge plans to turn old tyres into fuel

30 Sep 16 Lafarge has teamed up with a Canadian university to support testing of a low-carbon fuel derived from old tyres.

The partnership with Dalhousie University researcher Dr Mark Gibson will allow low-carbon fuel testing to be carried out on an industrial scale. The initiative, which is being carried out under a grant from the Natural Sciences & Engineering Research Council of Canada (NSERC), will research the adoption of low-carbon fuels in the cement industry. The tyre-derived fuel will be tested as an alternative for the cement industry at the Lafarge Brookfield plant.

Recent laboratory studies conducted by Gibson and his colleagues show that tyre-derived fuel has the potential to lower CO2 emissions compared with coal-derived fuel when co-fired in cement kilns.

"My students and I are very pleased to see this work enter the real world,” said Gibson. “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. We also expect that the use of tire-derived fuel will reduce NOx emissions as well as make excellent use of scrap tyres otherwise being landfilled.”
