US: CarbonCure has demonstrated an integrated CO₂ capture and utilisation (CCU) process from cement for concrete production in January 2018 at Cementos Argos’ Roberta plant in Calera, Alabama. The consortium - comprising Carbon Cure, Sustainable Energy Solutions (SES), Praxair, Cementos Argos and Kline Consulting - says it is the world’s first project to collect cement kiln CO₂ for subsequent utilisation downstream in concrete production and construction.

CO₂ emissions from the Roberta cement plant were captured by SES’ Cryogenic CO₂ Capture technology, transported by Praxair and reused in Cementos Argos' Glenwood, Atlanta concrete operations equipped with CarbonCure's CO₂ utilisation technology. The concrete manufactured with the waste CO₂ from the Roberta cement plant was then used in a local construction project in the greater Atlanta area. Design partners and fellow members of CarbonCure’s Carbon XPRIZE team such as LS3P Architects, Uzun + Case Structural Engineering, and Walter P Moore Structural Engineers completed the end to end integrated solution by creating demand for CarbonCure concrete products in the marketplace. Kline Consulting oversaw the commissioning and reporting of the industrial demonstration.

The project was an extension of Team CarbonCure's participation in the US$20m NRG COSIA Carbon XPRIZE Challenge, which incentivises and accelerates the development of integrated CCU technologies and new markets that convert CO₂ emissions from coal and natural gas power generation into valuable products.

UK: Nine cement and concrete companies have launched the Global Cement & Concrete Association (GCCA), a new association that intends to develop the sector’s role in sustainable construction. The association also wants to build innovation throughout the construction value chain, in collaboration with both industry associations and architects and engineers.

The GCCA will be led by international cement companies and headquartered in London, complementing and supporting the work done by existing associations at national and regional level. Membership of the GCCA is available for cement manufacturers from all over the world that share the organisation’s values, and partnerships will be developed with organisations that share its vision. GCCA’s founding members are Cemex, CNBM, CRH, Dangote, Eurocement, HeidelbergCement, LafargeHolcim, Taiheiyo and Votorantim. They represent 1046Mt of cement production capacity, according to the Global Cement Top 100 Report.
