Austria/Australia: Refractory producer RHI Magnesita and Calix say they have started a memorandum of understanding to develop a flash calciner for use in the production of refractory materials, to enable CO₂ separation for either utilisation or storage. The companies have agreed to run studies up to and including basic front-end engineering and design for a commercial-scale demonstration facility at an RHI Magnesita site.

RHI Magnesita and Calix started discussing a collaboration in early 2019. The application of Calix's technology to refractory products has been the subject of pilot scale test work during 2020, with larger scale test work currently underway.

Luis Bittencourt, chief technology officer of RHI Magnesita said, "We are pleased to be working with Calix on this project, which is a key part of the research and development programme on CO₂ emissions reduction that we are carrying out over the next five years. Together with our partners at Calix, we are seeking to develop new technologies for the capture, storage and utilisation of CO₂ that would otherwise be emitted during the refractory production process." Phil Hodgson, the managing director of Calix added that the company was also looking at strategic opportunities in its magnesium oxide businesses.

Brazil: Votorantim Cimentos is preparing to bid for some of LafargeHolcim’s assets in Brazil. However, the company is limited by local competition rules so it is unable to try and buy all of LafargeHolcim’s assets, according the Valor Economico newspaper. In a statement to Reuters, Votorantim said that it had not made a bid yet but that it was always open to new opportunities. LafargeHolcim was reported by local press in April 2021 as wanting to sell its assets in the country.

India: Researchers at the Visvesvaraya National Institute of Technology in Nagpur, Maharashtra, have shown in laboratory studies that an enzyme called urease found in watermelon seeds can strengthen cementitious materials and repair cracks in concrete. The Times of India newspaper has reported that the study found around a 22% increase in compressive strength, a 19% reduction in water absorption and improvements in durability. It is hoped that the food industry waste product could potentially be used to replace chemical admixtures commonly used in concrete production. Field studies are now set to follow.

Study leader associate professor Madhuwanti Latkar said, “Watermelon seeds are magic beans when it comes to importing strength to cementitious materials.”

Uruguay: The Administación Nacional de Combustibles, Alcohol y Portland (ANCAP) and the Administración de Ferrocarriles del Estado (AFE) have signed an agreement to exchange logistics services, materials and real estate. Under the deal ANCAP estimates that 380,000tt/yr of fuel and 390,000t/yr of cement and limestone can be transported by rail. The arrangement also includes: offering preferential transport rates to ANCAP; moving cement and limestone between ANCAP’s plants and quarries; conducting restorative work at ANCAP’s Queguay limestone quarry and its integrated Paysandú cement plant; and supplying rail ballast to AFE.
