UK: A team of researchers from six UK universities has filed a patent for a clinkerless cement product called Cambridge Electric Cement. Local press has reported that the project, called UK Fires, saw researchers successfully produce the cement using renewable power from recycled cement powder and ground granulated blast furnace slag (GGBFS). Following its successes, UK Fires has obtained a further Euro2m in funding from the UK Engineering and Physical Sciences Research Council (EPSRC) to continue its work into the range of concrete wastes suitable for use in Cambridge Electric Cement production.

India: UltraTech Cement has successfully commissioned a second clinker line with a capacity of 2.7Mt/yr at its Hirmi cement plant in Chhattisgarh. The company says that it is on track to also commission a new 1.3Mt/yr grinding unit at the plant in mid-2022.

Australia: James Hardie recorded sales of US$3.61bn in its 2022 financial year, up by 24% year-on-year from US$2.91bn in its 2021 financial year. The group’s North American fibre cement sales rose by 25% to US$2.55bn from US$2.04bn. Its Asia Pacific fibre cement sales rose by 22% to US$545m from US$446m, while its Europe building products sales rose by 20% to US$421m from US$351m.

Interim chief executive officer Harold Wiens said, “I am delighted to report that the James Hardie team has continued to deliver strong execution of our global strategy. This is reflected in strong price/mix growth in all three regions, including North America price/mix growth of 12%, Asia Pacific price/mix growth of 11% and Europe price/mix growth of 14%. The global team’s success in delivering high value products is the result of: one - enabling our customers to make more money by selling more James Hardie products; and two - marketing directly to the homeowners to create demand for our high value products through our customers.”

The group reaffirmed its 2023 financial year adjusted net income guidance range of US$740 - 820m.

Germany: The Ministry for Economy and Climate Protection has presented HeidelbergCement with its German Climate and Environment Innovation Prize (IKU) for its ReConcrete-360° concrete recycling process. The process retrieves hardened cement paste from waste demolition concrete for use in place of limestone in clinker and cement production. The recycled material can also bind CO₂ to act as a carbon sink.

Global research and development Wolfgang Dienemann said “With ReConcrete-360°, we have succeeded in developing a limestone substitute from demolished concrete that also allows us to use the carbon-containing exhaust gases from cement production. A small revolution with a big impact: In Germany alone, the CO₂ savings potential of this process is 10Mt/yr. The IKU award underlines that we can be proud of our pioneering innovation.”
