"It’s a major contributor to climate change — the way buildings and roads are made with concrete. It’s also a problem that’s growing as more of the world develops. So the race has been on to find solutions for a material that’s responsible for roughly 8% of global carbon dioxide emissions.

Now one California startup has developed a technology that reduces carbon dioxide in the making of cement and could have the potential to operate at large scale. Fortera intercepts carbon dioxide exhaust from the kilns where cement is made and routes it back in to make additional cement. In its first effort at commercial scale, the technology is being added to a CalPortland facility in Redding, California, one of the largest cement plants in the western U.S. It opens Friday.

“Our target is about being a ubiquitous solution that can work really at any plant,” said Ryan Gilliam, Fortera CEO. "
