Utilisation of CO2 for the development of low emission concrete

Concrete4Change （C4C）是一家屡获殊荣的研发公司，其使命是通过在混凝土内碳捕获利用和储存（CCUS）方面的颠覆性技术创新，使建筑行业脱碳。由于热力学障碍，大多数二氧化碳利用技术的操作成本很高，但在混凝土中的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年）。C4C最近在格拉斯哥举行的第26届联合国气候大会上获得了联合国“最具创新性净零转型技术”奖——气候杯、欧盟技术协会（EUTECH）颁发的可持续发展目标奖和英国皇家工程院奖。7月，C4C被邀请到上议院展示其技术。C4C一直在不断壮大；并受邀在英国预制联合会、知识转移网络、英国工业协会和其他一些知名组织展示其技术，以帮助建筑业向净零排放过渡。混凝土是地球上仅次于水的最常用材料，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%。Concrete4Change （C4C）正在开发一项屡获殊荣的专利技术，该技术可以将二氧化碳永久锁定在混凝土中，这是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的预拌料和预制应用。二氧化碳的封存（利用）可以增强混凝土的强度；因此，减少混凝土所需的水泥含量达到标准配方。二氧化碳封存和减少水泥用量都有助于减少混凝土的碳足迹。到2040年，这种CCUS技术有可能减少20亿吨二氧化碳排放，相当于欧盟年总排放量。C4C技术将成为全球净零技术生态系统的基本组成部分，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.
