A proposed project for the St. Marys Ciment McInnis operation in eastern Quebec envisions gradual replacement of a portion of the petroleum coke currently used for kiln combustion with low-carbon alternative fuels, including forest biomass. The objective is to achieve an estimated 20% thermal substitution rate by 2030 and up to 70% longer term.
St. Marys proposes installation of new equipment to process and feed the alternative fuels, including a grinder, dryer and enclosed storage facilities. They are intended to support the plant’s energy transition while incorporating measures to mitigate environmental impacts.
“This project represents an important step in reducing our plant’s carbon footprint. We want to advance this energy conversion while remaining responsive to the community and relying on solutions tailored to the realities of the region,” said Ciment McInnis Director of Operations Philippe Marceau.
The alternative fuels migration is being carried out in collaboration with Mi’gmawei Mawiomi Business Corp., the economic development arm of the Mi’gmaq communities of Gespeg, Gesgapegiag and Listuguj. The collaboration is based on an Impact and Benefit Agreement, as well as years of joint work to promote the sustainable use of forest biomass and development of a circular economy in Quebec’s Gaspé region.
