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.”

Uzbekistan: China-based Anhui Conch has started building a 2.5Mt/yr cement plant in Akhangaran district in Tashkent. It will invest US$200m in the upcoming plant, of which it has already spent US$16.7m on imported equipment, according to the Podrobno news agency. The plant will occupy a 183ha site.

Argentina: Loma Negra has inaugurated the second production line at its L’Amalí cement plant. The El Cronista newspaper has reported that the InterCement subsidiary invested US$350m in the line, which expands the plant’s capacity by 40%.

It previously said it was close to commissioning the grinding mill and despatch unit for the line in August 2021.

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.”

Canada: France-based Fives FCB has secured a contract to upgrade the grinding unit at Ciment Québec’s Saint Basile integrated plant in Quebec. The supplier will install two FCB Horomill grinding workshops with FCB TSV 5000 THF classifiers, FCB aerodecanters and flash dryers and Fives TGT process filters. It said that its mills met the customer’s specifications: namely zero water use; minimum power consumption; data processing; and full automation with rapid recipe change.

Ciments Québec president and chief executive officer Luc Papillon said “After a thorough technical review of the various technologies available today for cement grinding, we have selected the Horomill, being confident that it is the best adapted solution for our multiple cements portfolio and our quest to reduce our cement environmental footprint.”

China: Australia-based FCT Combustion has announced a formal alliance with air pollution control partner Enelco Environmental Technology (EET). Together the companies will target the Chinese cement, steel, glass and other markets. EET has become the exclusive China representative of FCT Combustion, with which it shares its capabilities and resources in the service of Chinese customers.

The two companies have set up a joint office in Nanjing, Jiangsu province. A workshop in Bengbu, Anhui province will support its work. FCT Combustion and EET also plan to launch local technical support, engineering and procurement teams for customers in China.

FCT Group chief executive officer Adriano Greco said “We have great respect for our growing customer base within China and believe that it is important to establish a locally based business unit so that we can deliver the best outcomes and customer experiences, providing customer service and engineering according to the local culture and language, as well as local procurement to offer the most cost-effective solution.”

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.

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."

Germany: Aerzen Rental has added its new TVS2500 air compressor to its 10-bar range of air compressors. Parent company Aerzen said that it developed the TVS2500 to set the standard for power density, energy efficiency and quiet running. The compressor is designed for large material volumes. A frequency converter facilitates optimal pressure and volume flow control, while variable speed control also enables a gentle start with a low starting current. The device can be used in any existing power network. Efficient cooling inside the units further ensures a regular supply of compressed air at ambient temperatures of up to 45°C.
