US: A research team at Washington State University has developed admixtures using chitin derived from seashells. The Moscow-Pullman Daily News has reported that the substance enhances concrete’s performance when substituted for some of the cement content. The lower clinker factor may also decrease net emissions. Work has shown that lower volumes of the supplementary material are required compared to existing admixtures.

UK: Business consultant Catax has reported an 8% year-on-year rise in the UK construction sector’s research and development spending in 2020 to Euro432m from Euro401m in 2019. Total UK spending in the area across all sectors grew by 5% year-on-year to Euro45.1m. Gross domestic product fell by 9%.

Chief executive officer Mark Tighe said, “The pandemic stopped businesses in their tracks but those reliant on innovation clearly didn’t take their foot off the gas.” He added, “The construction sector shut completely in the first lockdown but, even so, the industry still grew its research and development spending on an annual basis last year. This will put the sector on a strong footing as we recover from the impact of the pandemic.”

Japan: Taiheiyo Cement plans to set up a Carbon Neutral Technology Development Project Team in April 2021. The team will develop and apply carbon capture and storage (CCS) technologies for installation at the producer’s cement kilns. The company said that the team seeks to develop cost-practical product for industrial application. Following on from this, it plans to develop CCS technologies which make use of other cement plant processes, and which integrates the circular economic use of industrial by-products. Carbon neutrality is the ultimate aim.

The group said, “By establishing a new project team that is a cross-company organisation, we will gather our wisdom and realise carbon neutrality. We will strongly promote the development of innovative technologies for this purpose.”

Japan: Taiheiyo Cement has developed Nanoritia, a lithium manganese iron phosphate salt for use as a positive electrode material for lithium-ion batteries. The company says that the product has ‘excellent’ thermal stability and does not contain cobalt or nickel, which can sometimes be harder to source. As a result of the success, it will establish a 100t/yr nanoritia plant at its Central Research Laboratory in Sakura city, Chiba prefecture.

The group said, “We will proactively and swiftly develop and commercialise the production technology of this product, and contribute to the reduction of CO₂ emissions through the provision of materials for lithium-ion batteries. We will continue to strongly promote the group's management philosophy of business activities that are in harmony with not only economic development but also consideration for the environment and contribution to society, aiming to play a leading role in opening up a sustainable future for the earth.”

The cement and minerals producer has also been working on recycling large lithium-ion batteries at its integrated Tsuruga plant.

Spain: Cementos La Cruz has partnered with other building materials, construction and waste management companies and the Murcia Technological Centre for Construction to support a study by the Polytechnic University of Cartagena (UPCT). The Europa Press newspaper has reported that the research aims to develop geopolymeric concretes from industrial and urban waste, without the use of cement. The study is 80% financed by the European Regional Development Fund (ERDF).

UPCT science and advanced construction technology research group coordinator Carlos Parra said, “Stopping the use of concrete is not the solution, as it is a relatively accessible material that allows access to housing and multiple services for millions of people around the world and is also a material with high resilience against natural catastrophes such as floods, hurricanes and resistant to the passage of time.”

UK: HeidelbergCement subsidiary Hanson has installed a solar and wind-powered hydrogen generation demonstration unit at its Port Talbot Regen ground granulated blast furnace slag (GGBFS) plant in Port Talbot in Neath Port Talbot. The company says that the project is part of a collaboration with Swansea University’s Energy Safety Research Institute under the European Research and Development Fund’s Reducing Industrial Carbon Emissions initiative. The hydrogen generated by the installation will replace natural gas in the GGBFS plant’s burners.

Head of sustainability Marian Garfield said, “It is estimated that cement is the source of just under 2% of UK CO₂ emissions. With demand for cement and cement replacement products predicted to increase by 25% by 2030, researchers and industry are working hard to reduce the level of CO₂ emissions associated with production. As a leading manufacturer, we take our responsibility very seriously. In the UK we have already achieved a 30% reduction in CO₂ emissions since 1990 across the business and have set an ambitious new target of a 50% reduction by 2030 from the same baseline. We are constantly looking to improve energy efficiency and carbon reduction at our cement and Regen GGBFS plants, so we are delighted to be involved with this innovative research project.”

Europe/North America: Switzerland-based LafargeHolcim and US-based Schlumberger plan to study the feasibility of carbon capture and storage (CCS) systems at two cement plants in Europe and North America. The companies say that the partnership is intended to as a precursor towards the deployment of large-scale CCS solutions.

LafargeHolcim’s chief sustainability officer Magali Anderson said, “Today’s announcement is further proof of LafargeHolcim’s environmental leadership and commitment to pioneer new solutions to reduce carbon emissions on our journey to become a net zero company. Our partnership with Schlumberger, the world’s leading provider of technology to the global energy industry, will bring new advances in storage that could be replicated at scale across our sites.”

Germany: Mexico-based Cemex has announced its planned participation in Australia-based Calix and others’ LEILAC (Low Emissions Intensity Lime And Cement) 2 carbon capture and storage (CCS) project at HeidelbergCement’s Hanover cement plant in Lower Saxony. Cemex previously assisted the LEILAC partnership at its first installation at HeidelbergCement’s cement plant in Lixhe in Belgium. The company said that it will contribute to the technology's development utilising its gasification process expertise, leveraging its skills in alternative fuel (AF) consumption and computational fluid dynamic simulation design.

Global head of research and development Davide Zampini said, "Our participation in the LEILAC 2 project is another example of our continued efforts to deliver net-zero CO₂ concrete products globally by 2050. We are determined to have a significant direct involvement in research and development efforts pursuing high impact technologies in carbon capture, use, and storage."

Italy: An agreement between Italcementi and its unions has confirmed that its Bergamo research centre to stay in Italy. The agreement with the FenealUil, Filca-Cisl, Fillea-Cgil, Italcementi RSU unions is intended to preserve jobs at the company, maintain at least 15,000 hours/yr of research at the site and dedicate at least 1% of the company’s profits towards research and innovation. Parent company HeidelbergCement was reportedly considering a relocation of the centre to Heidelberg in Baden Württemberg, Germany in late 2020.

Separately, Italcementi’s grinding plant at Salerno has been approved to continue producing white cement. The decision follows staff cuts at the cement producer, according to the Il Mattino newspaper.

Tunisia: Carthage University, Ciments de Bizerte, the Tunisian Ministry of Higher Education and Scientific Research and the University of Algarve faculty of science and technology have concluded a study into the heavy metal content of CEM-I and CEM-II cement. The study found that both types of cement contain traces of arsenic, barium, boron, cadmium, chromium, copper, manganese, nickel, lead, strontium and zinc in equal measure, according to the Journal of Engineering.

Carthage University said, "Heavy metals in cement can originate from a variety of processes in production, including their initial presence in raw materials and fuel, incorporation into kiln refractory brick, metal erosion from the raw material grinding process and in additives such as gypsum, as well as cement kiln dust."
