Germany: Holcim Deutschland says that the preliminary test phase of a new CO₂ separation unit at its Höver cement plant in Lower Saxony has delivered positive results. Plant manager Stephan Hinrichs said that the company was “delighted” with the results so far. In late 2021 Cool Planet Technologies and Hereon signed a memorandum of understanding with Holcim Deutschland to deliver a carbon capture system for a carbon capture and storage (CCS) trial at the plant based on Hereon’s PolyActive membrane technology.

The next stage of the project will start in August 2022 and it will last until late 2024. This will include a one-year active test phase, in which the system is to be examined in long-term operation, planned to start in September 2023. If the results are good enough then the carbon capture unit will be expanded step-by-step so that after the final expansion stage it can separate around 90% of the CO₂ emissions and deliver high-purity CO₂ in liquid form for sequestration or further use. The ultimate aim of the project is to demonstrate performance, economy and operational behaviour on a larger scale in order to check whether the technology can be used at both Höver and other cement plants. Continued funding for the scheme is dependent on an application to the Competence Centre on Climate Change Mitigation in Energy-Intensive Industries (KEI) as part of the Decarbonisation in Industry program.

US: Cemex USA has applied for a permit to continue mining at Dowe Flats to support operations at its integrated Lyons cement plant in Colorado. It has asked the Boulder County Community Planning and Permitting department to allow it continue mining for 15 years until 2037, according to the Daily Camera newspaper. It then says it will close the cement plant. Its existing mining permit will end later in 2022.

UK: Aggregate Industries’ Cauldon cement plant in Staffordshire has become the first industrial facility to operate a PRISMA liquid air energy storage system. Green technology developer Innovatium developed the product in collaboration with the University of Birmingham. The supplier says that it can deliver 25% energy savings for air compression and will help Aggregate Industries to realise its 2030 goal of 500kg/t of CO₂ emissions for its cementitious products.

Aggregate Industries sustainability director Kirstin McCarthy said “We are very proud to be the first partner to install the PRISMA system in an operational environment. Aggregate Industries is committed to transitioning to net zero, and supporting innovations like PRISMA is vital in helping us achieve that goal. McCarthy continued “We believe PRISMA can play a major role in addressing the ‘energy trilemma’ of managing energy efficiency, energy cost and energy security, and we're confident that its installation at Cauldon will further prove its decarbonisation credentials - a big step towards full commercialisation of the technology.”

Nigeria: Dangote Cement sales volumes in the first quarter of 2022 have been hampered by disruptions to gas supplies domestically and by high freight rates restricting its exports of cement and clinker to Cameroon, Ghana and Sierra Leone. Its sales volumes of cement fell by 3.6% year-on-year to 7.25Mt in the first quarter of 2022 from 7.52Mt in the same period in 2021. Its revenue grew by 24% to US$994m from US$801m. Its earnings before interest, taxation, depreciation and amortisation (EBITDA) increased by 18.6% to US$508m from US$428m.

Michael Pucheros, the chief executive officer of Dangote Cement, said “Our group volumes were down 3.6% mainly due to energy supply challenges in Nigeria. Our operations relying on cement and clinker imports – namely Ghana, Sierra-Leone, Cameroon - were impacted by the global supply chain challenges.” Additionally, its operations outside of Nigeria was also negatively affected by a cement plant in Congo being shut for over two months due to maintenance and repairs and extended power plant maintenance in Senegal.

US: Argos USA has launched its new Portland Limestone Cement (PLC) brand EcoStrong.The company says the its will complete its conversion to 100% EcoStrong PLC cement production across all facilities in 2023.Its Roberta, Alabama cement plant and Atlanta, Georgia grinding plant will transition by mid-2022, while its Newberry, Florida cement plant will transition by October 2022.Argos USA plans to use EcoStrong cement at all of its Eastern US ready-mix concretesites by mid-2022.

Cement technical director Steve Wilcox said“I am excited to be part of Argos’ brand announcement for our PLC Type IL product. EcoStrong PLC encompasses everything we have worked for over the past decade, to offer a high-quality product with lower embodied carbon, which contributes to the ultimate goal of decarbonising across our operations. Our PLC product is engineered to reduce the harmful effects on the environment and perform similar to or better than our ordinaryPortland cement (OPC) Type I/II. EcoStrong PLC empowers our customers, specifiers, architects, and engineers to design and execute their projects with resilience and sustainability.”

Canada: The Government of Quebec says it will allocate up to US$36m towards a US$110m upgrade project at Ciment Québec’s integrated St Basile plant. The plant intends to build a new grinding unit including new reception, storage and raw material handling systems and two mills. The work is intended to reduce the CO₂ emissions from the plant. France-based Fives FCB previously said that it had won a contract for the project. Commissioning of the new equipment is scheduled for the beginning of 2024.

Dominican Republic: Colacem Group subsidiary Domicem has awarded the contract to upgrade the limestone reclaiming system at its integrated Sabana Grande de Palenque cement plant in San Cristóbal province to Italy-based Bedeschi. The original stacking and reclaiming equipment, installed by Bedeschi in 2004, allows clay and limestone handling at the plant. The upgraded machine will improve the limestone reclaiming system, increasing its capacity from 200t/hr to 360t/hr, the capacity needed in order to feed a new production line that is being installed at the plant.

India: Dalmia Cement (Bharat) has signed a memorandum of understanding (MOU) with Denmark-based FLSmidth to collaborate in the research and development of sustainable solutions for cement manufacturing. The agreement has been arranged under the ‘Green Strategic Partnership’ initiatives between Denmark and India that cover energy and climate change.

Under the MOU both companies will cooperate on a range of areas such as substituting conventional energy supplies with renewable sources and working towards CO₂ emissions abatement. Both companies have committed to contributing research and development towards eventually building an industrial scale production plant where the new concepts can be further tested.

Mahendra Singhi, the managing director and chief executive officer of Dalmia Cement (Bharat) said, “In alignment with the ambitious net zero vision of our Prime Minister Narendra Modiji and given the strength and stature of our respective organisations, this association will provide futuristic solutions to the cement and concrete industry to emerge clean and green.” He added that India and Dalmia Cement in particular were keen to develop a roadmap for the implementation of Industry 4.0 with totally decarbonised cement plants and a ‘lighthouse’ cement plant.

Zimbabwe: South Africa-based PPC has held a groundbreaking ceremony for a US$40m project to build solar power plants with a joint output of 30MW to support its integrated Bulawayo and Colleen Bawn cement plants. The Bulawayo plant will set up a 10MW plant, with 5MW earmarked for internal use, while the Colleen Bawn plant will develop a 20MW capacity, 12MW being used internally, according to the Chronicle newspaper. The excess electricity will be fed in the national grid. PPC has chosen ATC Consortium to build and operate the solar plants under a 20-year power purchase agreement.

Dominican Republic: Mexico-based Cemex has reopened the second production line at its integrated San Pedro Macoris plant. The decision will add 0.5Mt/yr to the plant’s production capacity bringing its total to 2.5Mt/yr. The decision has been made to support customers in the Caribbean market. Other recent investment in the country by Cemex include new packaging machines, palletisers, hydro combustion, new trucks and tanks.

Jesús González, the president of Cemex South, Central America and the Caribbean said “The reactivation of the production line is a clear example of our commitment to the sustainable development of the Dominican Republic. This investment contributes to the revitalisation of the national economy, promotes exports, reduces the need for imports and supports employment and a more sustainable environment in the country."
