UK: The Mineral Products Association (MPA) has announced the successful completion of a trial of cement production using a net-zero fuel mix consisting of hydrogen and refuse-derived fuel (RDF) at Hanson’s Ribblesdale, Lancashire, cement plant. The RDF in the mix consists of meat and bone meal (MBM) from the food industry and glycerol from biodiesel production.

Increased alternative fuel (AF) substitution is one of seven key levers in the MPA’s Roadmap Beyond Net Zero emissions reduction strategy. The association says that the fuel will eliminate 180,000t/yr of CO₂ emissions from the Ribblesdale plant’s operations when fully implemented. The project received Euro3.71m in government funding.

Hanson’s environmental sustainability manager Iain Walpole said “We are delighted to be involved with this world-leading project, which is a further example of our commitment to cutting CO₂ emissions.” He added “It will also contribute to our ambition of supplying net zero carbon concrete by 2050.”

Croatia: Holcim Croatia plans to invest Euro1.28m to upgrade the dosing equipment of its Koromačno cement plant’s kiln line. The planned upgrade will enable the line to increase the proportion of alternative materials used in its cement production, thus equipping the plant for low-carbon cement production. Innovation Norway has granted the producer Euro441,000 towards the cost of the project.

Managing director Nikola Kovačević said “Mineral admixtures in cement have a threefold benefit: on the one hand, different characteristics are created in the cement to meet the requirements of different types of construction; on the other hand, the exploitation of natural resources decreases. Thirdly, the carbon footprint of the cement is thus reduced through the lowering of the clinker factor.”

India: JK Cement has successfully completed an upgrade of Line 3 of its Nimbahera, Rajasthan, cement plant. The upgraded line has a 30% expanded capacity of 6500t/day, compared to 5000t/day previously.

The plant produces some cement for export to countries including Bahrain, the UAE, Nigeria, South Africa and Tanzania.

India: Birla Corporation has announced plans for a 92% increase of its installed cement production capacity to 30Mt/yr by 2027 from 15.6Mt/yr. The company’s upcoming 3.9Mt/yr Mukutban cement plant near Nagpur, Maharashtra, is scheduled for commissioning in early 2022. The impacts of the Covid-19 outbreak increased the project’s cost by 12% to US$370m from US$330m. The Times of India has reported that the group’s next phase of expansion will focus on the operations of the former Reliance Cement Company. Birla Corporation acquired the company in 2016.
