St. Marys Cement (SMC) a company of Votorantim Cimentos North America (VCNA) is undertaking efforts to use Alternative Low Carbon Fuels (ALCF) as an energy source for their St Marys Cement Plant (the Site). This initiative will help reduce greenhouse gas emissions in Ontario while diverting materials from landfills. The Site is located at 400 Bowmanville Ave, Bowmanville, Ontario.


Demonstration Trial

St Marys Cement (SMC) has current Environmental Compliance Approvals (ECAs), Numbers 4614-826K9W and 1255-7QVJ2N, that were issued on November 5, 2014 and March 11, 2015, respectively, to undertake an Alternative Fuel Demonstration project. The purpose of the Demonstration Project was to demonstrate the use of alternative fuels at the facility and assess potential environmental effects associated with the use of alternative fuels at the facility relevant to baseline conditions. SMC completed the alternative fuel demonstration trials from September 25, 2018 to December 10, 2018.

​Alternative Low Carbon Fuel Study

​In keeping with best practices being implemented around the world, SMC currently has an ECA to use woody materials as an ALCF at the site and has initiated a study to support the preparation of an ALCF Application under Ontario Regulation (O. Reg) 79/15 of the Environmental Protection Act to expand the current use of ALCFs at the Site. SMC is proposing to undertake studies and prepare an application to support the following:
  • ​​increase the daily throughput of ALCFs at the Site from 100 tonnes per day to 400 tonnes per day;​
  • add biomass, cellulosic and plastic materials derived from industrial and/or post-consumer sources, which cannot be recycled, are not considered hazardous and are not derived from animals or the processing and preparations of food, to the list of approved ALCFs at the Site based on the recent demonstration project at the site;
  • install new equipment at the Site to feed ALCFs; and
  • increase alternative fuels storage at the Site using enclosed containers and buildings

Two open houses will be held as part of the project to respond to questions from the community and present the environmental studies results.

Reports and Dates

The demonstration trial and ALCF study results will be posted in the documents section of this website in the near future.

When confirmed, the Open House dates will be posted in the News section of this website, along with any new documents.
