LafargeHolcim is increasing its efforts to further improve the carbon-efficiency of its cements with the launch of Project CO₂MENT at its Richmond, B.C., Canada, plant. The objective is to build the world’s first full-cycle solution to capture and reuse CO2 from a cement plant while also reducing greenhouse gas emissions. The project is a partnership between Lafarge Canada, Inventys and Total.

Over the next four years, Project CO₂MENT will demonstrate and evaluate Inventys’ CO₂ Capture System and a selection of LafargeHolcim’s carbon utilization technologies at its Richmond cement plant. The project has three phases and is expected to be fully operational by the end of 2020. Subject to the pilot’s success, the vision is to scale up the project and explore how the facility can be replicated across other LafargeHolcim plants.

During the first phase, the partners will work on purifying the cement flue gas in preparation for CO2 capture. The second phase will focus on the separation of CO2 from flue gas using a customized cement version of Inventys’ carbon capture technology at pilot scale. As part of the final phase, the captured CO2 will be prepared for reuse and support the economical assessment and demonstration of CO2 conversion technologies onsite, such as CO2 injected concrete and fly ash.

The  Richmond plant recently launched a new and improved lower carbon fuel (LCF) system to reduce greenhouse gas emissions associated with the production of cement. It will also help minimize landfill waste; specifically, non-recyclable plastics that are creating a backlog for municipalities across Canada.

The CAD $28 million system is expected to replace up to 50% of fossil fuel use with lower carbon fuels and could result in a 20% reduction of combustion emissions. It also allows Lafarge Canada to divert approximately 100,000 tonnes annually of waste from local landfills, the equivalent of about 8,300 loaded garbage trucks.

René Thibault, region head North America, said, “LafargeHolcim is committed to reducing CO2 emissions and we are excited to join forces with Inventys and Total through Project CO₂MENT. We hope to discover ways to capture emissions from our production processes and reuse them in our products, advancing a circular economy even further than today. The recent launch of the new LCF system at our Richmond plant aims to make the facility the most carbon efficient cement plant in Canada. Our investment alongside funding support from the British Columbia Ministry of Environment and Climate Change Strategy has made the system economically viable and demonstrates a long-term commitment to the environment as well as the British Columbia cement market.”
