Adbri secures bauxite supply from ABx Group

11 September 2023

Australia: Adbri has awarded ABx Group a contract to supply 90,000 – 120,000t of bauxite to its Birkenhead, South Australia, cement plant over a five-year period from early 2024. Business News has reported a ‘conservative’ estimated value for the contract of US$5.4m. ABx Group will supply bauxite from its DL130 mining project. The project commands 13.7Mt-worth of bauxite reserves across three deposits. Mining is due to begin in October 2023. The parties have agreed an undisclosed price for the first shipment of bauxite under the contract.

ABx Group managing director and CEO Mark Cooksey said "This represents a significant milestone for ABx and endorses the suitability of our bauxite for the broader cement industry. It enables both parties to plan for ongoing supply with confidence. Importantly, regular mining operations to supply Adbri will increase ABx's ability to secure additional customers, for which there are active discussions."

Synhelion and Cemex España to build solar-fuelled clinker plant near Madrid

14 August 2023

Spain: 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 that Synhelion’s thermochemical reactor further helps to capture CO2 emissions from clinker production. A study by the Swiss Federal Institute of Technology Lausanne indicated that this can halve the cost of carbon capture at cement plants, to below Euro85/t.

New standard clears geopolymer concrete for infrastructure applications in Australia

04 August 2023

Australia: 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 ground granulated blast furnace slag (GGBFS) and pulverised fly ash, by virtue of its binder technology. Wagners previously supplied EFC for the London Power Tunnels project in the UK, based on local technical approval-based building codes. The producer now expects a new standard like the Australian one to follow in the EU.
