Fortera continues construction of low-carbon cementitious material plant at CalPortland's Redding cement plant – Global Cement

US: In 2022, Fortera began building a 15,000t/yr-capacity plant to produce its low-carbon cementitious material, Fortera Reactive Calcium Carbonate (RCC), at CalPortland’s Redding cement plant in California. The commercial-scale plant will produce a reactive form of calcium carbonate using CO2 from the kiln of the 600,000t/yr cement plant. Fortera’s process converts 1t of limestone into 1t of Fortera RCC by capturing and mineralising CO2 from the cement plant’s kiln. Fortera cement production emits 60% less CO2 than ordinary Portland cement (OPC). The 15,000t/yr plant will operate at 20 times the scale of previous pilot tests. The Redding Record newspaper has reported that 15 workers will be employed at the site.
Former Redding cement plant owner Lehigh Hanson formed an agreement with Fortera to collaborate on the low-carbon cement plant project in March 2021. The plant subsequently switched ownership to Martin Marietta Materials in October 2021, before CalPortland bought it in July 2022.
