Brazil: Cimento Nacional, part of Buzzi, has selected Fuller Technologies to supply a second ball mill and separator system for its Pitimibu plant, replicating the equipment successfully installed in 2013. The original setup was a UMS 5.0 x 17 ball mill combined with an O-SEPA® N4500 separator, which has operated reliably for over a decade, according to the company. The company has now ordered an updated version of the system. The new package includes a next-generation O-SEPA® separator with a fine drive for increased rotation speed and high-Blaine cement output, and a high-efficiency air seal designed to reduce coarse bypass and improve final cement quality.

UK: First Graphene has announced the successful large-scale production of around 600t of graphene-enhanced cement at Breedon’s Hope Cement Works in Derbyshire ahead of new trial projects rolling out across the UK. The batch contains 3t of First Graphene’s PureGRAPH-CEM® additive, and was produced in a single day. The product is now in storage ahead of despatch for use in three concrete projects across the UK. The University of Manchester will conduct compressive strength testing and analysis of the concrete’s performance.  The additive is introduced during the final milling stage, and is designed to reduce CO₂ emissions by up to 16% by lowering the clinker content in the cement.

The first trial involves using 30-40t of the graphene-enhanced cement to produce thousands of roof tiles at FP McCann’s Cadeby plant in Leicestershire. The five-month study is part of an Innovate UK-funded initiative aiming to improve resource efficiency and reduce construction waste in response to the UK government’s housing targets. First Graphene has also reportedly received further interest from organisations in both the UK and Australia for testing the material in various applications.

First Graphene CEO Michael Bell said “Adding graphene into cement has proven to deliver performance benefits for a wide range of applications, and multiple end uses of this cement batch reinforces PureGRAPH®'s versatility. We look forward to working closely with our strategic commercial partner Breedon, Morgan Sindall, FP McCann and the University of Manchester as application trials roll out over the coming months."

US: A new finish mill has officially been commissioned at the Durkee cement plant. The facility held a ribbon-cutting ceremony to celebrate the occasion. The upgrade will increase the plant’s cement production capacity by 210,000t/yr without increasing clinker production or associated CO₂ emissions. The company said the new finish mill enhances its ability to deliver consistent, high-performance cement.

US: Furno Materials has signed an agreement with ready-mix concrete producer Maschmeyer Concrete for the use of its compact modular cement kiln technology. Maschmeyer Concrete plans to operate the kilns using its 90,000t/yr of ‘waste’ concrete as a feedstock. The company will build an initial 50,000t/yr-capacity mini cement plant in Florida. The partners are currently conducting site analysis and a feasibility study for the project.

This latest deal brings Furno Materials’ total commitments to 295,000t/yr across announced and unannounced projects. The sale remains contingent on the successful deployment of its first commercial-scale reactor with concrete producer Ozinga in Chicago, Illinois.

Sweden: The Swedish Energy Agency has awarded US$12.5m to Boliden under its Industrial Leap initiative to support the development of a low-carbon cement alternative derived from iron-rich residual materials. The product allows for partial replacement of limestone in cement. Boliden is building an industrial demonstration plant to produce, test and verify the new material, which is based on byproducts from its own operations. Boliden estimates that the technology could cut value-chain emissions by around 600,000t/yr of CO₂ if fully implemented across its operations.

“Demonstrating innovative new technology to manufacture products with lower carbon emissions is fully in line with the purpose of the Industrial Leap. By reusing materials in new products instead of depositing them, the project also contributes to more circular use of materials,” said Klara Helstad, Deputy Head of the Department for Research, Innovation and Business Development at the Swedish Energy Agency.
