Draft:St Marys Cement

  • Comment: I'm not seeing significant secondary coverage of this company. Most sources cited are just routine reporting. The Canadian Mining Journal piece (Ref. 8) is good, but that's the only one in sight. Typically two secondary sources like this are a bare minimum for WP:NCORP, and for an article of this length I would expect more than two. WeirdNAnnoyed (talk) 11:39, 25 July 2025 (UTC)

St Marys Cement is a Canadian cement producer, that operates in the Great Lakes Region of North America.

History

St Marys Cement was founded in 1912 in the Southern Ontario town of St. Marys. Founded, by John Lind and Alfred Rogers as St. Mary's Portland Cement Ltd. when John Lind found a fortune in the Klondike Gold Rush, since then St Marys Cement has been a major and leading producer of cementitious materials in the Great Lakes Region.[1][2][3][4][5] St Marys operates 6 plants located in Canada and the United States.[1] St Marys Cement was acquired by Votorantim Cimentos, a Brazilian cement company in 2001.[6]

Production and Notable Projects

St Marys Cement (as a part of Votorantim Cimentos North America) has a production capacity of over five million metric tonnes.[7]

Notable projects using St Marys Cement include: The CN Tower, Maple Leaf Gardens, Darlington Nuclear Station, and more.[8]

Pollution

St Marys produces a lot of pollution. However, they have been monitoring and reducing emissions, and energy use.[9]

In, Bowmanville and St. Marys many residents complain about air quality, smells, and air pollution from local cement plants.[10][11] Concerns for Ontario residents are exacerbated by plans for limestone mining under Lake Ontario.[12][13]

St Marys receives funding from the Canadian Government to reduce emissions.[14]

With funding from the Canadian Government, St Marys Cement is installing specialty cement kiln infrastructure to reduce pollution. Which will remove 39,900 tonnes of greenhouse gas emissions in 2030. By 2023, Votorantim Cimentos (parent company of St Marys Cement) reduced CO2 emissions by 15 percent that, being compared to 2010.[15]

In 2022, air pollutant statistics for the Bowmanville Plant were as followed:[16]

  • Fine particulate matter: 3.44 tonnes
  • Respirable particulate matter: 15.13 tonnes
  • Total particulate matter: 34.53 tonnes

A massive decrease from 2013.[16] Showing the efforts of the company to lower pollution emissions.

Other efforts include:

  • Using algae photosynthesis to convert CO2 produced by the manufacturing process into biofuel.

St Marys Cement is believed to be the first in the world to use algae to capture CO2 from a cement plant. The project started in 2010.[17]

St Marys Cement’s Charlevoix plant will be the first in the world to use polymeric membrane technology to demonstrate cleaner industry, the project intends to show a 95% CO2 capture rate is possible and achievable.[18]

Controversies and Accidents

Proposals for expansions, such as proposed quarries, have been subject to fierce debates and controversies. Many of these have been attributed to local residents and NIMBY movements.[19]

On January 29, 2012, an accident occurred when workers were clearing mud and rock from the vanes of a large rotary sluice. A brake on the sluice failed, causing it to hit a worker in the head, causing a concussion. St Marys pleaded guilty and was fined $78,000.[20]

On October 8, 2019, a worker was severely injured while conducting testing on equipment. This resulted in a lawsuit in which St Marys pleaded guilty, and St Marys Cement was fined $165,000.[21][22]

On March 21, 2023, a worker was struck and pinned by a piece of machinery; the worker later died as a result of their injuries. As a result of this, St Marys issued 5 new requirements.[23]

All of these incidents occurred at the Bowmanville facility.
