Summit Materials recently converted 100% of the production at its Hannibal, Mo., plant, which is operated by Continental Cement Co., to portland-limestone cement (PLC).
Hannibal is the company’s second plant to transition to PLC this year; the Davenport, Iowa, plant began PLC production in April. The two plants produced a combined 2.1 million tons of cement in 2021.
“A lower carbon future requires the cooperation of the entire cement-concrete-construction value chain, and we are delighted with the quick adoption of PLC by our customers and specifiers who supported this pivotal change at our plants this year,” said David Loomes, Continental Cement president and senior vice president of Summit Materials. “In addition to shrinking our carbon footprint through the use of alternative fuels in the manufacturing process, the conversion to PLC reduces concrete embodied carbon by approximately 10% while delivering resilient and durable infrastructure to our communities in all Continental Cement markets where Hannibal and Davenport cement is supplied.”
Summit Materials CEO Anne Noonan added, “The PLC conversion at our Hannibal and Davenport plants reflects Summit’s target to reduce carbon emissions by 25% in 2030 and our goal to reach net zero by 2050 and furthers the larger industry effort to address climate change and build a more sustainable future through the Portland Cement Association’s Roadmap to Carbon Neutrality.”
