France: Germany-based ThyssenKrupp has won a contract for the installation of a new 4000t/day clinker line at Ciments Calcia’s Airvault cement plant in Poitou-Charentes. The supplier expects the new line to double the plant’s clinker capacity while also reducing its CO2 emissions. It is intended to replace the two existing lines at the site.

ThyssenKrupp will supply a 1200t/hr double-shaft hammer crusher, a longitudinal blending bed, a 370t/hr Quadropol QMR² 45/23 type vertical roller mill and a 10,000t tangential blending silo to process raw materials for the line. A single-string, five-stage Dopol type cyclone preheater with integral calciner will be supplied that is suitable to use with alternative fuels, with the possibility of conversion to oxyfuel in future. ThyssenKrupp plans to preassemble the preheater, reducing anticipated construction time ‘by several months.’ The plant also includes a Polytrack clinker cooler, a solid recovered fuel (SRF) preparation line and dedusting systems. Commissioning is scheduled for mid-2024.

No value for the project has been disclosed by Ciments Calcia or ThyssenKrupp. However, Ciments Calcia previously announced a proposed investment of Euro300m in January 2021.

Belgium: Environmental disclosure organisation CDP has listed Cemex, HeidelbergCement and Holcim among 200 companies on its 2021 Climate Change A List for actions to mitigate their CO2 emissions. Holcim’s Indian subsidiaries ACC and Ambuja Cements also received A ratings. Both ACC and Ambuja appeared on CDP’s 2021 Water Security A List, while Holcim scored an A-.

Chief executive officer Jan Jenisch said “Building on the launch of our nature-positive strategy this year, we set new and ambitious goals to achieve water security across our operations worldwide, with our colleagues from Ambuja in India leading the way. CDP’s rankings this year are a testimony to the tremendous work carried out by our 70,000 people around the world and a great encouragement for all of us to keep raising the bar.”

India: Dalmia Cement plans to invest US$75.2m in a 2.6Mt/yr expansion to its Bokaro grinding plant in Jharkhand. The company says that the work will increase the plant’s capacity by 70% to 6.3Mt/yr from 3.7Mt/yr. US$33.2m will go towards the installation of new solar power plant. The company will also set up a waste management facility at the site, using US$1.06m of the investment.

Managing director Puneet Dalmia said “As we are further investing in the Eastern India market to participate in its economic growth story, we are also taking our corporate responsibility seriously by placing the utmost importance on environmental protection and social impact. We are confident that the employment generated through our investments and the skill enhancement in our social initiatives will help create a progressive ecosystem where we help people become independent and self-sufficient. We are excited and look forward to partnering with the state to achieve our business, social and sustainability goals.”

India: Udaipur Cement Works has increased its solar power generation capacity by 43% through the installation of a new 4.35MW solar power plant at its Udaipur cement plant in Rajasthan. The 1.4Mt/yr cement plant now has a total solar power capacity of 14.5MW. Udaipur Cement Works says that solar power generated at the plant will reduce it operations’ CO₂ footprint by 14,000t/yr.

India: The Indian Green Building Council (IGBC) has certified the sustainability claims of Dalmia Cement’s portfolio of blended cements. The portfolio consists of composite cement, Portland pozzolan cement and Portland slag cement. The council employed a full-cycle assessment of the cements’ impacts.

Head of sales, marketing and logstics Sanjay Wali said “We see GreenPro’s accreditation as a milestone in our journey to becoming carbon-negative by 2040. This also reaffirms our blended cement products’ green supremacy, which is accelerating the global transition from a grey to green reality.”

Kenya: Affordable housing joint venture 14Trees and UK-based development finance company CDC Group have 3D printed a complex of 52 houses near Kilifi, Kilifi county. The development, called Mvule Gardens, uses an IFC-EDGE Advanced-certified sustainable design to support the ecological regeneration of its locale. Swtizerland-based Holcim, which holds a stake in 14Trees, supplied its TectorPrint ink for use in buildings’ walls to increase strength.

Holcim CEO Jan Jenisch said “We are excited to be building one of the world’s largest 3D-printed affordable housing projects in Kenya. With today’s rapid urbanisation, over 3bn people are expected to need affordable housing by 2030. This issue is most acute in Africa, with countries like Kenya already facing an estimated shortage of 2m houses. By deploying 3D printing, we can address this infrastructure gap at scale, to increase living standards for all.”

India: UltraTech Cement plans to increase the production capacity at its Maihar cement plant by 50%. Denmark-based FLSmidth will carry out the expansion project, which also involves the installation of a new calciner and JetFlex burner, along with other pyroprocessing equipment. The supplier says that the upgrade will facilitate greater alternative fuel substitution at the plant in Madhya Pradesh.

FLSmidth’s cement president Carsten Riisberg Lund said “We are pleased to continue our long-lasting collaboration with UltraTech Cement. With the new upgrades to the pyro sections, installing MissionZero flagship offerings, such as the low-NOx calciner and JetFlex burner, UltraTech makes a significant investment in future-proofing its sustainable production.”

UK: Innovative Ash Solutions has received a Euro588m Scottish government grant to establish a 20,000t/yr ash processing plant in South Lanarkshire. The Herald newpaper has reported that the plant will process boiler ash, cyclone ash and incineration fly ash for use in local cement production. When commissioned in 2022, the plant will eliminate 6104t/yr of CO₂ emissions, according to the operator. The government granted the funding under its Zero Waste Scotland circular economic investment scheme.

The company said “Using this new patented process, which diverts waste materials from landfill and avoids the use of virgin sand, creates a product which is cheaper and will reduce the environmental impact of cement production compared to the use of imported pulverised fuel ash.”

Innovative Ash Solutions is a joint venture of waste management company Levenseat and consultancy Organic Innovative Solutions.

US: LafargeHolcim US has announced the launch of TerCem, a blended cement which offers 65% reduced CO₂ emissions compared to ordinary Portland cement (OPC), according to the company. LafargeHolcim US will produce TerCem at its Whitehall, Pennsylvania, cement plant. The product joins its ECOPlanet low-carbon cement range.

Senior vice president sales Patrick Cleary said "We are leading a market transformation and taking a step towards a net-zero future. Our cement organisation has invested heavily in broadening the industry's range of superior sustainable products designed to lower our carbon footprint with no compromise in quality and long-term durability."

Poland: Lafarge Poland says it plans to stop production CEM I Ordinary Portland Cement (OPC) by the end of 2025.
