Cement: Support for sustainable technologies

The Global Cement and Concrete Association (GCCA) has revealed the first six start-ups that will be backed by its member companies as part of the first ever Innovandi ‘Open Challenge’ in the race to ‘net zero’ by 2050.

The six start-ups, which were chosen from more than 100 entrants to the Open Challenge, hail from the USA, Canada, UK, Italy and the Netherlands. They have now joined forces with world-leading cement companies to help drive further innovation in the industry and will each form part of formal consortia to further test, develop and deploy their ground-breaking technologies.

One of the key focuses of the industry is to develop the technology and implementation for carbon capture, utilisation and storage (CCUS), with CarbonOrO, MOF Technologies and Saipem among the start-ups that the industry is backing. GCCA members have committed to moving from the dozens of pilot projects and announcement already underway to having 10 industrial scale carbon capture plants by 2030 as part of the landmark Net Zero Roadmap, announced in October 2021. CCUS includes a range of technologies and methods that “capture” CO₂ from large sources – such as in industrial power generation. The CO₂ is then either used on site or compressed and transported to be used or stored elsewhere.

Carbon Upcycling Technologies and Fortera both use captured CO₂ to produce low-carbon cement and cementitious materials. The other confirmed start-up is Coomtech, a British business that has developed a low-cost drying technology using kinetic energy created by managed, turbulent air.

Six newly established consortia will help to accelerate the development of technologies that reduce or eliminate carbon throughout the cement and concrete value chain. Each consortium is made up of a start-up company, with their respective pioneering technology, and includes between three and eight cement companies, with 16 GCCA member companies involved across the six innovation consortia.
