California startup Fortera develops technology to recycle carbon dioxide emissions in cement production at CalPortland's Redding facility.

California startup Fortera develops technology to reduce carbon dioxide emissions in cement production, a major contributor to climate change. The method involves intercepting carbon dioxide exhaust from cement kilns and reusing it to make additional cement. The technology's first commercial-scale implementation will be at a CalPortland facility in Redding, California, a large cement plant in the western U.S.
