Switzerland-based Synhelion and Cemex España plan to build a new clinker plant near Madrid. The plant will use Synhelion’s synthetic fuel to produce clinker from clay and crushed sand at 1200°C. The fuel consists of a gas produced from green hydrogen and captured CO2, using solar heat. La Tribune de Genève Online News has reported
CemVision has reported the successful conclusion of a large-scale production pilot of its limestone-free alternative clinker. CemVision produces clinker using 100% supplementary cementitious materials (SCMs) from the steel and mining sectors. Possible examples of waste streams that could be used as SCMs include ground granulated blast furnace slag (GGBFS) and alkali-activated mine tailings. CemVision says
Alternative cement and concrete producers have welcomed a new Australian civil engineering standard that allows builders to use reduced-CO2 geopolymer concrete in infrastructure projects. Wagners, which produces Earth Friendly Concrete (EFC), said that the revision has removed on if its key barriers to wider market acceptance. EFC replaces 100% of cement with supplementary cementitious materials, including
France: Vicat and Materrup plan to build their first reduced-CO2 MCC1 raw clay cement plant at Carbonne in Occitanie. The plant will have a capacity of 60,000t/yr. Vicat and Materrup plan for their joint venture to subsequently build three further units across France. Vicat’s chair and chief executive officer Guy Sidos said “This new structure will enable
Asia Cement has launched its 2050 decarbonisation strategy, entitled ‘Net-Zero Carbon Emissions By 2050 – Asia Cement Advanced Deployment.’ The strategy consists of multiple pillars, namely ‘alternative fuels,’ ‘reducing cement’s clinker factor,’ ‘increasing renewable energy reliance’ and ‘carbon capture.’ During 2022, Asia Cement reduced its limestone, clay, iron and sand consumption by 266,000t, its coal
Breedon Cement commenced a 24-hour trial of graphene-enhanced cement production at its Hope Cement plant in Derbyshire on 28 June 2023. The trial advances the work of a consortium led by Australia-based First Graphene. It is using existing grinding aid dosage lines, with minimal adjustment required. Breedon Cement and its partners aim to produce 2000t
The Global Cement and Concrete Association (GCCA) has named the 15 anticipated deliverers of low-CO2 cement and concrete production shortlisted for participation in its second Innovandi Open Challenge. The association chose the start-ups based on their potential to deliver CO2 emissions reduction in the global cement and concrete sector in line with its Concrete Future 2050 Net
Ireland-based Ecocem has partnered with CB Green to launch a joint venture to scale up production of 70% reduced-CO2 cement based on Ecocem’s ACT technology. The technology combines widely available alternative raw materials into a product with enhanced strength and durability compared with ordinary Portland cement (OPC). The new joint venture will build a grinding plant
Heidelberg Materials North America inaugurated its 2.4Mt/yr Mitchell cement plant in Indiana on 14 July 2023. The plant is equipped with a 3600 bag/hr rotary packer, and also boasts a 154,000t-capacity clinker storage dome. It will produce Heidelberg Materials North America’s EcoCem Portland limestone cement (PLC), alongside other products. The producer said that the new
