India: JK Lakshmi Cement has partnered with the Society for Technology and Action for Rural Advancement (TARA) to integrate calcined clay technology into its operations in order to commence production of limestone calcined clay cement (LC3). United News of India has reported that the producer says that this type of composite cement reduces the product's clinker factor by 50% and its carbon footprint by 40%.

JK Lakshmi Cement said "This partnership will be a game-changer for the cement industry, giving impetus to its efforts in mitigating emissions, combating climate change and bringing a holistic change in the surrounding communities to create sustainable livelihoods in large numbers."

Mexico: Cemex recorded consolidated sales of US$3.77bn in 2022, up by 13% year-on-year from first-quarter 2021 levels. The group recorded operating earnings before interest, taxation, depreciation and amortisation (EBITDA) growth of 3% year-on-year, to US$691m. Cemex said that sales growth in its Europe, Middle East and Africa region led the earnings increase, supported by strong underlying demand conditions with robust volume growth in Europe and the US. It recorded double-digit like-for-like price rises across its global operations. During the quarter, group CO₂ emissions fell by 4% year-on-year.

Chief executive officer CEO Fernando González said “We are quite pleased with our first quarter performance despite the unprecedented global macro challenges. Against the backdrop of the worst inflation headwinds in more than 40 years, we achieved strong pricing traction across our products. Given the tight supply and demand dynamics in most of our markets, we are optimistic that we can recover input cost inflation. In addition, our diversified energy, supply chain and Climate Action strategies are paying off and helping us respond to energy cost pressures.”

Regarding the quarter’s sustainability achievements, González said “Our performance gives me great confidence that we can reach not only our 2030 climate goal but also our Net Zero ambition.”

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.

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.”

India: Bharathi Cement plans to build a US$17m automated terminal and packaging plant at Coimbatore, Tamil Nadu. United News of India has reported that the facility will package the company’s bagged and bulk cement and supply the South West Tamil Nadu and Kerala markets.

On 23 April 2022, the subsidiary of France-based Vicat despatched its first rake of cement aboard custom-built tank and box container cars to Coimbatore from its Kadapa, Andhra Pradesh, cement plant. Vicat’s India CEO Anoop Kumar Saxena said that the first-of-its method of bulk cement transportation will reduce the company’s logistics costs and carbon emission and increase the service level for customers.

Switzerland: Holcim recorded net sales of US$6.75bn in the first quarter of 2022, up by 20% year-on-year from US$5.62bn in the first quarter of 2021. The group’s recurring earnings before interest, taxation, depreciation and amortisation (EBIT) rose by 16% to US$643m from US$553m. The company has upgraded its outlook 2022 to a forecast of full-year net sales growth of at least 10%.

CEO Jan Jenisch said “I am very encouraged by the record start of the year, setting a solid foundation to our Strategy 2025 – Accelerating Green Growth.”

The first quarter of 2022 brought four new bolt-on acquisitions in addition to the group’s conclusion of its US$1.35bn Malarkey Roofing Products acquisition. The company says that it remains actively engaged in supporting humanitarian efforts in Ukraine.

Holcim has also published its industry-first Climate Report 2022. The report details the company’s progress towards achieving its sustainability targets under the four pillars of its Strategy 2025 – Accelerating Green Growth. Under the Accelerating Growth pillar, Holcim reached a total of 15 markets with its ECOPlanet reduced-CO₂ cement range. Under Expanding Solutions & Products, it reduced the proportion of cement sales in its consolidated sales to 57% in 2021 from 60% in 2020. Its other pillars are Leading in Innovation and Sustainability and Delivering Superior Performance. In 2021, the company used 6.6Mt of recycled construction and demolition waste in its products, against a 2050 target of 10Mt.

Chief sustainability and innovation officer Magali Anderson said “On our net-zero journey, we are walking the talk at Holcim, taking clear science-driven action to win the race for climate.”

Middle East/North Africa: The World Cement Association (WCA) has called on its members in the Middle East and North African cement sectors to take new actions towards industry decarbonisation. UAE-based consultant and WCA member A3 & Co has said that companies in the region have the potential to cut their carbon footprints by up to 30% with no new capital expenditure required. The Middle East and North Africa accounted for 15% of global cement production in 2021. In the region, only the UAE and Saudi Arabia have committed to national net zero carbon targets, for 2050 and 2060 respectively.

WCA CEO Ian Riley said “There has been a lot of discussion in Europe and North America about decarbonisation roadmaps for the cement industry and good work has been done to start on this journey. However, 90% of the world’s cement is produced and used in developing countries; to impact overall industry emissions we must include these stakeholders. Cement companies in the Middle East have some low hanging fruit to take advantage of, which will lower costs at the same time as reducing CO2 emissions. At WCA we have a number of programmes that can help them realise this opportunity."

Canada: Carbon Upcycling Technologies has secured US$6.15m in financing from a group of companies led by Clean Energy Ventures, Cemex Ventures, Amplify Capital and Oxy Low Carbon Ventures (OLCV). The investment round includes participation from Zero Carbon Partners, Purpose ESG, Clean Energy Venture Group, Fund for Sustainability and Energy, Prithvi Ventures, Bryan Trudel, and Mark and Faye McGregor. Carbon Upcycling intends to use the funding to grow its team and build its second commercial-scale facility in North America, with a production capacity of over 200t/day of its cement and concrete additive. Carbon Upcycling sequesters CO₂ in secondary cementitious materials such as fly ash, which are then used in cement or concrete production.

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.
