Introducing the use of Alternative Low-Carbon Fuels (ALCFs) at our Mississauga, Ontario cement plant will mark a significant step towards reducing greenhouse gas (GHG) emissions, enhancing sustainability, and further strengthening the environmental responsibility component of our cement production process.
Shifting to Alternative Low-Carbon Fuels (ALCF) in the Ontario cement industry has reduced fossil fuel usage and diverted large volumes of non-recyclable materials from landfills. Ash Grove will carefully select ALCF feedstocks to both maintain cement quality and comply with updated air quality standards. The Ash Grove team, in conjunction with technical experts, are carefully evaluating the impact to emissions for each proposed alternative low carbon fuel. These rigorous engineering studies and air emission modeling exercises will evaluate compliance with air quality standards, specified under Ontario Regulation 419/05. Furthermore, the introduction of ALCF fuels is expected to slightly decrease NOx emission and there is no anticipated impact to SO2 emissions.
ALCF materials will be primarily sourced from other industrial and commercial processes and will have gone through rigorous sorting and processing before arriving at the Ash Grove Mississauga cement plant. You can find a comprehensive list of materials that are not permitted to be used as ALCFs in Ontario under O.Reg 79/15 Schedule 1.
More details on the ALCF Environmental Compliance Approval (ECA) Application process will be available on our website soon. The first public review opportunity was on September 12, 2024.

The Mississauga cement plant is actively pursuing its decarbonization goals.
With this initiative and other investments, the plant will shift from coal combustion to natural gas. This transition to natural gas is anticipated to begin in 2027 and is expected to reduce the facility's CO2 emissions by up to 85,000 tons per year when the transition to natural gas is complete. Additionally, this project is a significant step towards the plant's goal of achieving net-zero emissions by 2050.

Ash Grove’s Mississauga Plant has been recycling and participating in the circular economy by receiving material from construction sites and integrating it as a raw material in the production of cement. The goal is to minimize the amount of virgin materials and energy entering our production systems. This initiative also reduces construction and/or demolition materials in the local economy from going to landfills (i.e. shale extracted from excavation projects are consumed in the process).

We are investing $100 million at our Mississauga Plant on a robust Action Plan that will significantly reduce emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx) from our cement-making process over the next ten years.
In 2023, we also moved to a new air dispersion model that contains more stringent parameters for air quality consistent with the Ministry of Environment, Conservation and Parks’ (MECP) requested changes.
A Site-Specific Standard (SSS) is a long-standing MECP regulatory tool that is responsive to the modified modelling and provides the time required by our facility’s technology, engineering, and operations teams to fully implement the Action Plan’s significant emissions-reducing improvements.
The Ash Grove Mississauga cement plant site specific standard application for SO2 and NOx was submitted in January 2024. The application is currently with the Ministry of Environment Conservation and Parks (MECP) for technical review. Supporting the MECP’s review is a top priority of the Ash Grove Mississauga team. The next opportunity to the community to comment on the application will be at the Environmental Registry of ON posting. When the ERO posting is available for public comment, Ash Grove will update our website.

The Community Advisory Panel (CAP) was established as a voluntary measure to maintain ongoing communications with local residents and stakeholders.
The CAP’s Mission is to:
• Provide, encourage, and facilitate two-way communication between local residents/regional stakeholders and Ash Grove on the operation of the Mississauga Plant including environmental, economic, and social issues of mutual concern.
• Educate stakeholder groups and the community on the importance of cement/concrete in our society.
• Maintain/improve relationships with neighbours and community organizations.The COVID-19 pandemic impacted the frequency of the CAP meetings.

Fish stocking is a fisheries management tool for meeting specific goals including supporting recreational fisheries and species restoration. The Ministry of Natural Resources and Forestry (MNRF) stocks approximately 1.5 to 2 million fish per year in the Ontario waters of Lake Ontario. Fish are raised at one of nine MNRF fish culture stations.
Ogden Point has been an excellent stocking site. The hatchery trucks can get quite close to the water, and the fish are released into good habitats near deeper water so they can quickly find their preferred depth and temperature. The stocking events started in 2019 and, to date, the MNRF has stocked nearly 290,000 fish at Ogden Point. The fish have been a combination of Lake Trout and Brown Trout. The fish are approximately 16 months of age at the time of release (known as ‘spring yearlings’) and weigh 30 to 40 grams.

In 2023, the Mississauga Plant hosted their first open house since 2018. It brought together over 650 politicians, neighbours, employees, and community partners to:
Raise awareness of the plant and its operations
Strengthen relationships with community members and politicians
Highlight our improved environmental performance over the past few decades and our plans to continue this important path
Show the hard work and dedication of the plant employees and show our commitment to the areas where we operate

Ash Grove is committed to mitigation through a comprehensive Climate Change Strategy aimed at reducing greenhouse gas emissions (GHG) from the plant.
CRH, Ash Grove’s parent company, has outlined a comprehensive plan to reduce overall emissions and innovate for a low-carbon future. Ash Grove’s cement production plays a key role in the low-carbon strategies for CRH, and we are committed to meeting our 2030 targets at the Mississauga Plant.

Carbon Upcycling Technology (CUT) is a pilot project at the Ash Grove Mississauga facility. The cutting-edge Canadian technology will help the facility reduce CO2 emissions through proprietary milling and CO2-capturing technology that permanently sequesters CO2. The pilot facility has the potential to reduce CO2 emissions by approx. 12,000 tonnes per year. A full-scale plant can reduce CO2 emissions at the Mississauga Plant by approx. 60,000 tonnes per year compared to conventional cement production.
-
General Use Limestone, or Portland Limestone cement, is a type of cement produced at the Mississauga Plant. Clinker (produced in the kiln through the combustion process) is a main component of cement and a main driver of CO2 emissions. GUL cement has a lower ratio of clinker, on a per tonne basis, and this reduction in clinker makes it a less carbon-intensive product.
-
The upgrades to the existing separator will help support Ash Grove’s GHG reduction roadmap and increased market demand for low-carbon cement products. The approx. 15M+ investment is expected to reduce CO2 emissions intensity by approx. 10,000-15,000 tonnes per year.
-
For decades, Ash Grove has been an active participant in the circular economy and recycling of materials. The Mississauga Plant has been using alternative raw materials from other industries to supplement the inputs into the cement production process, like slag from the steel industry. These alternative raw materials help to improve the overall carbon intensity of the product.

To reduce Point of Impingement concentrations, Ash Grove will spend the next few years focusing on operating procedures. To reduce the maximum emissions at the facility, the Ash Grove team will focus on analyzing existing data to identify processes that can impact, and help further reduce our SO2 emissions.
-
In addition to the existing lime injection and abatement technology, Ash Grove will investigate implementing additional abatement measures on other stacks to further reduce SO2 emissions.
-
To reduce our impact on our community and improve environmental performance, Ash Grove has committed to investing in a large capital project to discharge all emissions through the main stack. This will improve the dispersion characteristics and support reduction to the generic air standard limits.
