UK: Breedon Group, together with Australia-based First Graphene, Morgan Sindall Construction & Infrastructure and the University of Manchester, is developing a new reduced-CO₂ graphene-enhanced cement. The consortium is currently formulating the cement using varying doses of First Graphene’s PureGRAPH graphene-enhanced grinding aid. The project received a research grant from the UK government earlier in 2022. First Graphene says that the study involves one of the largest commercial trials of its kind to date globally. It is simultaneously collaborating on another similar trial with a Europe-based speciality chemicals producer.

On 29 September 2022, First Graphene launched its latest range of graphene-enhanced cement grinding aids and concrete additives. These join recent launches PureGRAPH AM, an admixture developed in collaboration with South Africa-based Nanoproof/Glade Chemicals, and HexMortar, a dry mortar mix which will be distributed by New Zealand-based GtM Action.

First Graphene says that its cement and concrete segment’s order pipeline totals US$113m in value. Managing director and chief executive officer Michael Bell said “It is pleasing to see our efforts, and those of our collaboration partners, coming to fruition at a commercial scale. One of the primary drivers for the adoption of graphene solutions in this segment is the reduction of CO₂ emissions. We’re seeing considerable benefits both in the immediate reductions that can be achieved through the use of graphene-enhanced grinding aids, as well as the potential reductions in concrete usage because of the enhanced physical properties these products provide.” Bell concluded “Working with industry-focused partners such as Nanoproof/Glade Chemicals, GtM Action, Breedon Cement and Fosroc opens the way to an estimated addressable market of more than 12,000t of PureGRAPH across the medium to long term.”

Europe: RHI Magnesita is heading a European Union Horizon project called ReSoURCE. The project seeks to develop a sensor-based refractory waste sorting and powder handling system. It involves academic partners in Austria, Germany, Ireland, Norway and the UK. The European Health and Digital Executive Agency (HADEA) supplied Euro6m in funding for the study, while the UK government supplied Euro1m. Global refractory waste generation is currently 28Mt/yr.

RHI Magnesita chief executive officer Stefan Borgas said “On average, 60% of all spent refractories generated by refractory-consuming industries go to landfill, while only 30% are recycled. With the ReSoURCE project, we aim to increase it up to 75%. This means we can achieve significant savings of CO₂ emissions per annum. With this research project, we have the chance to make a difference in the world.”

US: Lehigh Hanson has secured US$3.7m-worth of funding from the US department of energy for its planned front-end engineering design (FEED) installation of a carbon capture system at its Mitchell cement plant in Indiana. The funding was part of a total US$31m pot awarded to 10 different carbon capture projects across multiple industries. All of the projects have the capacity to capture over 95% of emissions from their respective plants.

Mitsubishi Heavy Industries America is supplying its carbon capture system for use at the Mitchell cement plant, at a total project cost of US$4.8m.

Australia: Adbri is part of a consortium of eight Australian industrial manufacturers, developers and port operators collaborating with AGL Energy on a feasibility study for a green hydrogen plant at the site of the latter’s Torrens Island power plant in South Australia. AFR Online News has reported that any future hydrogen plant established by the partners would rely on solar and wind power, which has large potential in the region.

The South Australian government previously launched its first US$414m green hydrogen project in Whyalla in March 2022.

Russia: A study commissioned by the National Association of Manufacturers of Building Materials and the Construction Industry (NOPSM), SM PRO and Soyuzcement, the national cement manufacturing union, has found that 80% of components required for repairs and upgrades to cement plants in Russia are manufactured abroad. The research was intended to assess the sector’s requirement for foreign equipment and to determine the prospects for import substitution. The results of the survey were presented in late May 2022.

Anton Solon, the executive chair of NOPSM, noted that Russian cement sector holds a ‘critical’ dependence on imported equipment. He said that domestic analogues were either ‘significantly’ inferior to imports or simply not available. The main equipment affected included separators, burners, drives, compressors and grinding mills. Parts for packaging lines, some types of quarry equipment, grinding media, refractories, additives and linings were also negatively affected. However, he did point out that low-efficiency and large-sized gas cleaning plants (including bag and electrostatic precipitators) were produced domestically. Vyacheslav Shmatov, the chairman of Soyuzcement, called for the development of local engineering products to remedy the situation.

Mexico: Cemex has reported its successful completion of laboratory tests aimed at converting CO₂ emitted by cement kilns into carbon nanomaterials. The producer said that it was able to turn 50% of available carbon in a flue gas stream into nanomaterials. Possible industrial uses for carbon nanomaterials include in building materials, biomedicines, electronics and agriculture. Cemex says that its next step will be to scale the technology for a cement plant pilot study.

CEO Fernando Gonzalez said “This breakthrough technology is significant for Cemex, not only because it offers the potential to commercialise carbon emissions, but because it demonstrates the value of our Smart Innovation platform. The path to carbon neutrality will be built with innovation, and we remain committed to being at the forefront in developing new circular technologies and processes.”

Germany: Rohrdorfer and Austria-based Andritz Group are in the process of installing a 2t/day CO₂ separation plant on the roof of the former’s Rohrdorf cement plant in Bavaria. The pilot plant will capture CO₂ from the plant’s emissions for use by the regional chemicals industry. The Ingenieur newspaper has reported that it will cost Euro3m and is scheduled for commissioning before June 2022. It is the first installation of its kind at a German cement plant.

Rohrdorfer’s plant and process engineering manager Helmut Leibinger said “We must begin to see CO₂ as a product of value rather than a problem. With CO₂ as a carbon source, Germany can protect the climate and at the same time become less dependent on oil and natural gas. In addition, value creation and jobs will remain in the country.”

Spain: Cemex’s Mósteles clinker pilot batch production unit at IMDEA Energy Institute in Madrid Autonomous Community has produced its first batch of solar-heated clinker. The unit uses Switzerland-based Synhelion solar radiation technology. The technology uses a solar receiver and gaseous heat transfer fluid to heat raw materials.

Cemex chief executive officer Fernando Gonzalez said “The production of the first solar clinker is an exciting milestone for this transformational technology. It is proof of our commitment to deliver tangible outcomes through innovation to achieve our goal of delivering only net-zero CO₂ concrete by 2050.” He concluded “Cemex is building a better future, and that future must be sustainable.”

Spain: LafargeHolcim España has announced the launch of a joint venture called ECCO2 with Carbon Clean and Sistemas de Calor. The joint venture will develop carbon capture technology for use at the producer’s Carboneras cement plant in Almería. It will then seek to market captured CO₂ from the plant for use as a gas in local agricultural greenhouses. When commissioned in early 2023, the carbon capture system will have the capacity to capture 10% of the Carboneras plant’s CO2 emissions.

Japan: Taiheiyo Cement is among 13 participant companies whose proposed carbon capture, utilisation and storage (CCUS) demonstration hub has received approval to proceed with funding from the Japan Ministry of the Environment. Nikkei Business Trends News has reported that Toshiba Energy Systems and Solutions, Uyeno Transtech, JGC, Chiyoda, Taisei Corporation, the University of Tokyo, Kyushu University, Japan NUS, the National Institute of Advanced Industrial Science and Technology and QJ Science also collaborated in the development of the CCUS system. The trial will begin in early 2022 and conclude in the 2025 financial year.
