Utilisation of CO2 for the development of low emission concrete

Concrete 4Change（C4 C）是一家屡获殊荣的研发公司，其使命是通过碳捕获利用和混凝土内储存（CCUS）的颠覆性技术创新来实现建筑行业的脱碳。由于热力学障碍，大多数CO2利用技术的操作成本都很高，但混凝土利用已被证明是仅有的两种可以产生积极环境投资回报的方法之一（密歇根大学2021）. C4 C最近在格拉斯哥的COP-26上获得了联合国“最具创新性的净零过渡技术”奖，即气候杯，欧盟技术商会（EUTECH）颁发的SDG奖和皇家工程院奖。7月，C4 C应邀到上议院展示其技术。C4 C一直在不断发展壮大;并已被邀请通过在英国预制联合会，知识转移网络，CitA和其他各种知名组织展示其技术来帮助建筑行业向净零过渡。混凝土是地球上除水之外使用最多的材料，目前占全球二氧化碳排放量的8%以上。到2050年，这将达到全球二氧化碳排放量的40%。Concrete 4Change（C4 C）正在开发一项屡获殊荣的专利技术，该技术将二氧化碳永久锁定在混凝土中，作为CCUS最安全的方法。其载波技术的效率是目前市场领先者的10倍。它适用于结构和非结构预拌和预制应用。封存（利用）CO2可提高混凝土的强度，从而减少达到标准配方所需的混凝土水泥含量。二氧化碳封存和水泥减量都有助于减少混凝土的碳足迹。这项CCUS技术有可能在2040年前减少20亿吨二氧化碳排放量，相当于欧盟每年的总排放量。C4 C技术将成为全球净零技术生态系统的重要组成部分，帮助企业和政府实现净零目标。

Concrete4Change (C4C) is an award-winning R&D company on a mission to decarbonise the construction industry through disruptive technological innovation in carbon capture utilisation and storage within concrete (CCUS). Majority of CO2 utilisation techniques are expensive to operate due to thermodynamic barriers however utilisation in concrete has been shown to be one of the only two methodologies that can produce a positive environmental return on investment (Michigan University 2021).C4C recently won the United Nations "Most innovative Net Zero Transition Technology' award, The Climate Cup, at COP-26 in Glasgow, the SDG award from EU Technology Chamber (EUTECH) and the Royal Academy of Engineering Prize. In July C4C was invited to House of Lord to present its technology. C4C has been going from strength to strength; and has been invited to help the construction industry transition to net zero by presenting its technology at the British Precast Federation, Knowledge Transfer Network, CitA and various other high-profile organisations.Concrete is the most used material on earth after water and currently accounts for over 8% of global CO2 emissions. This will reach 40% of global CO2 emissions by 2050\. Concrete4Change (C4C) is developing an award-winning, patented technology that takes CO2 and permanently locks it into concrete as the safest method for CCUS. Its carrier technology is 10 times more efficient than the current market leader. It is applicable in structural and non-structural ready-mix and precast applications.The sequestration (utilisation) of CO2 results in the strength enhancement of concrete; hence, reducing the amount of cement content of concrete required to achieve standard recipes. Both CO2 sequestration and cement reduction can contribute to the reduction of the concrete's carbon footprint. This CCUS technology has the potential to mitigate 2 billion tonnes of CO2 emissions by 2040, the equivalent of total EU emissions p.a. The C4C technology will be a fundamental part of the global net-zero technology ecosystem, helping companies and governments achieve their net zero targets.
