India: ACC has launched Holcim’s Houses of Tomorrow sustainable homebuilding initiative with the construction of a low CO₂ home in Puducherry called Gratitude Villa. Projects Today News has reported that architect Trupti Doshi selected building materials to reduce CO₂ emissions by 40% by comparison to conventional materials such as ordinary Portland cement (OPC). She opted for ACC’s Suraksha brand cement, fly ash bricks and ECOPact green concrete.

India: ACC’s earnings before taxation, interest, depreciation and amortisation (EBTIDA) fell by 26% year-on-year to US$83.1m in the first quarter of 2022 from US$113m in the same period in 2021. Net sales rose by 3% to US$566m from US$552m. Sales volumes of cement dropped by 3% to 7.71Mt but volumes of ready-mixed concrete grew by 5% to 0.87Mm³. The subsidiary of Ambuja Cement and Holcim said that its costs had been negatively affected by a global rise in fuel costs caused by ‘geopolitical events.’

The cement producer said that its new integrated plant at Ametha in Madhya Pradesh is scheduled to be commissioned in the fourth quarter of 2022. It commissioned an upgrade to its Tikaria grinding plant in Uttar Pradesh in February 2022. Waste heat recovery unit projects at its Jamul and Kymore plants are ‘on track’ and the board of ACC has approved the next phase of similar projects at its Chanda and Wadi plants.

France: CRH subsidiary Eqiom has successfully commissioned its Gennevilliers construction waste recycling pilot plant. Prior to the plant’s opening, Eqiom recycled 10,000t of construction waste in the first quarter of 2022. It is now aiming to recycle 50,000t in 2022.

The company says that its continual efforts are making the circular economy possible in the construction sector.

China: CNBM’s sales revenue grew by 7% year-on-year to US$43.1bn in 2021 from US$40.1bn. Its sales volumes of cement and clinker fell by 3% to 332Mt and 13% to 40.4Mt respectively. Concrete sales volumes increased slightly to 112Mm³. Its adjusted earnings before interest, taxation, depreciation and amortisation (EBITDA) rose by 7% to US$8.11bn from US$7.6bn. The group increased its average cement prices by 10% in 2021. However, the group’s sales revenue from its engineering division fell by 29% to US$421m from US$590m, although its earnings recovered significantly. The group blamed this on “great uncertainty” in overseas markets due to the coronavirus pandemic although it said that producer’s willingness to invest was starting to recover.

Zhou Yuxian, chair of CNBM, said “The year 2021 was an extraordinary and tough year. In the face of complex environment abroad and numerous risks and challenges, China adhered to the general keynote of seeking progress in a stable manner, coordinating prevention and control of the Covid-19 pandemic and the development of economy and society, continuing the national economic recovery, taking a new step in building a new development pattern and achieving a good start of the 14th Five-Year Plan.”

Mexico: Cemex has published its 2021 Integrated Report. Under the report’s Climate Action section, Cemex recorded a 4.7% year-on-year decrease in its CO₂ emissions per tonne of cementitious material. Alternative fuel (AF) substitution rose to 29%, while its products’ average clinker factor fell to 75%. It was the first company to complete a global roll-out of its reduced-CO₂ cement and concrete range (Vertua). It established Science-Based Targets Initiative (SBTi)-verified well below 2°C 2030 climate action goals and joined the UN’s Race to Zero and the Business Ambition for 1.5°C coalition. It also became a founding member of the World Economic Forum’s First Movers Coalition for zero-carbon economic development.

The year also brought major Sustainability and Circular Economy milestones, including managing 57 times the volume of waste it sent to landfill, positively impacting 25m lives through its Social Impact Strategy and processing 61% of global sales through its Cemex Go digital sales platform. For the second consecutive year, its Net Promotor Score was 68, ‘substantially above’ the construction and engineering industry average.

Finland: Betolar has signed a letter of intent with Australia-based RISAB and the Vanadium Recovery Project to research the use of steel slag from which vanadium has been extracted in concrete production. Dow Jones Institutional News has reported that the company says that, through it Geoprime alkali-activated additive technology, the new slag source could replace 10% of the cement used in concrete production in Finland.

CEO Matti Löppönen said "We see a huge opportunity for Betolar here. If successful, we would be able to offer our customers a specific, currently unused slag of the steel industry to replace cement in concrete. Our customers already have experience in utilising other types of slag in the production of concrete using Geoprime. Utilising new side streams will expand the reach of our solution as planned.”

Betolar launched Geoprime in September 2021. It is currently developing a recipe-optimising artificial intelligence (AI) and data platform to bring together concrete producers and suppliers of slag, ash and other materials.

UK: Concrete admixture producer Oscrete UK has appointed Matthew Gabriel to the role of new product development and sustainability manager. The company says that the appointment strengthens its commitment to sustainable construction.

Gabriel said “With the environment at the forefront of everyone’s minds, and customers looking to increase their use of supplementary cementitious materials (SCM), my priority is to develop products and processes which support our customers’ own route towards low carbon concrete.” He continued “Finding cost effective green solutions without impacting performance is key to the future of the construction sector. We are now looking to develop products that can help our customers to use or increase the use of products with a lower eCO₂, hence the creation of a role dedicated entirely to this arena.”

US: Argos USA has agreed to sell a total of 23 US ready-mix concrete batching plants to Smyrna Ready Mix Concrete for US$93m. 18of the plants are situated in North Carolina and the remainder in Southwest Florida.

India: The India Cements has launched Concrete Super King, a general application cement, and Halo Super King, a cement exclusively developed for use in the production of precast hollow dense concrete blocks.

Vice chair and managing director Narayanaswami Srinivasan said that many of the company’s customers already rely on its products in their precast hollow dense concrete block production. With the launch of Halo Super King, it hopes to further increase the ease of application.

Greece: Titan Cement recorded Euro1.71bn in net sales in 2021, up by 6.7% year-on-year from Euro1.61bn in 2020.

Its earnings before interest, taxation, depreciation and amortisation (EBITDA) dropped by 4.6% to Euro272m from Euro286m, due to an ‘unprecedented’ second-half costs increase. The group’s net profit was Euro89.6m, compared to Euro1.1m in 2020. During the year, Titan Cement increased the digitisation of its cement production and continued its on-going share buyback programme. Its Scope 1 and 2 CO2 emissions declined by 4% year-on-year, in line with its 2030 target trajectory.

Titan Cement said “Having already achieved the 2025 targets for energy efficiency and zero waste-to-landfill certification, the group’s attention is now focused on empowering business ecosystems to incorporate sustainability considerations in their decision making. To ensure that key suppliers meet the group’s environmental, social and governance (ESG) standards, Titan Cement developed a sustainable supply chain roadmap and published the first Titan Group Procurement Policy.” In the coming year, the group plans to ‘continue to harness the advantages offered by decarbonisation, digital transformation and business model innovation to benefit our customers, employees, suppliers and communities, aspiring to deliver to society carbon-neutral concrete by 2050.’
