Solidia Technologies has entered into a technology licensing arrangement with CalPortland for the license of certain patents that enable up to a 50% reduction in the carbon footprint of cement and concrete.
The limited licenses will allow CalPortland to use the Solidia technology in the Western United States in furtherance of its development of low carbon solutions. CalPortland also purchased certain lab and plant assets from Solidia.
“CalPortland continues to focus on decarbonization opportunities that lead to meaningful and innovative carbon reduction for the cement and concrete industries,” said CalPortland COO Bill Mullen. “Our Carbon Reduction Team has worked diligently with Solidia Technologies to enter into this licensing agreement and asset purchase that will help us achieve our sustainability goals.”
Solidia Cement is a low-limestone cement that gains strength through carbonation – exposure to CO2 – rather than hydration like traditional portland cement. It is made using the same raw materials and equipment as portland cement; however, Solidia Cement achieves significant CO2 reductions from lower production temperatures and reduced limestone calcination.
Following the divestiture to CalPortland, Solidia expects to continue to work with licensing partners to provide its low carbon solutions embodied in more than 300 patents and patent applications across the globe.
