Buzzi Unicem USA and Alamo Cement company change Portland cement production to enhance sustainability in their operations
In keeping with their commitment to the environment and the Portland Cement Association’s Roadmap to Carbon Neutrality, Buzzi Unicem USA announced the full conversion from traditional ASTM C150 Type I and II cements (OPC) to ASTM C595 Type IL (PLC) cement to improve CO2 footprint. The conversion began with plants in Cape Girardeau and Festus, Missouri; Greencastle, Indiana; Maryneal, Texas; and Pryor, Oklahoma, which made the transition to Type IL (PLC) by the end of Q1 2022. Alamo Cement Company in San Antonio, Texas, completed its transition by mid-2022 followed by Chattanooga, Tennessee, plant in Q3 2022. And finally, Stockertown, Pennsylvania, plant was fully converted at the end of 2022.
These excellent products have been widely used in Europe (as well as other countries) for many years and have a lower CO2 emissions intensity than the ones of cements commonly used up to now by our customers in the USA.
The Portland limestone cements developed by Buzzi Unicem USA have the same performance characteristics as standard Portland cement, they can be produced at any plant in the country and are distributed in both bulk and in bags.
Type IL (PLC) 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 reaching carbon neutrality by 2050.
