In keeping with their commitment to the environment and the Portland Cement Association’s Roadmap to Carbon Neutrality goals, Buzzi Unicem USA and Alamo Cement Co. will transition from ASTM C150 Types I and II portland cement production to ASTM C595 Type IL, or portland-limestone cement.
CEO Massimo Toso said the companies will implement the full conversion by the end of 2022.
“The conversion begins with our plants in Cape Girardeau and Festus, Mo.; Greencastle, Ind.; Maryneal, Texas; and Pryor, Okla., making the transition to Type IL (PLC) by the end of Q1 2022,” Toso said. “Alamo Cement in San Antonio will complete its transition by mid-2022 followed by our Chattanooga, Tenn., plant in Q3 2022. And finally, our Stockertown, Pa., plant will fully convert by year end.”
Portland-limestone cement can reduce the CO2 emissions up to 15% in comparison with traditional cement.
“With these changes, Buzzi Unicem USA and Alamo Cement are supporting the cement industry’s goal of reducing carbon emission intensity,” concluded Toso.
