This first-of-its-kind plant executes Fortera’s patented ReCarb® process technology on a commercial scale, while also providing the building and industrial sectors with a scalable solution to drastically reduce carbon emissions.

Located on CalPortland’s campus at Redding, CA, the Fortera Redding ReCarb Plant takes industrial CO₂ from CalPortland’s kiln and mineralizes it through Fortera’s patented ReCarb process, creating ReAct® — the market leader in green cement solution.

CalPortland is pleased to see construction of the Fortera plant progressing at our Redding facility. We’re excited to see how the ReAct® product can best be utilized to achieve industry’s decarbonization goals.
