Sweden: Nordkalk has produced lime at its Koping lime plant using 30% biofuel as alternative fuel (AF). The producer now aims to increase the substitution rate to 50%. Nordkalk subsidiary Kalkproduktion Storugns recently began trialling 100% liquid biofuel substitution in continuous operations at its Larbro lime plant. ENP Newswire has reported that both projects are part of a CO₂ emissions reduction initiative in partnership with the Swedish Energy Agency and Umea University.

Egypt: Heidelberg Materials subsidiary Suez Cement has invested US$16m in upgrading its operations towards increased alternative fuel (AF) use since 2010. The producer uses AF in the burners and kilns of all three of its cement plants, at Helwan, Kattameya and Suez. Meanwhile, Suez Cement has invested US$60m in dust control measures over the same period. Other on-going investments include US$25m in the construction of a waste heat recovery (WHR) plant at the Helwan cement plant. The company is committed to reaching a 24% reduction in its CO₂ emissions between 2019 and 2030.

Technical director Omar Khorshid said “We are committed to pursue initiatives to broaden our range of innovative and eco-friendly building solutions, advance operational efficiency through digitalisation and strengthen customer engagement for better business results and more positive impact."

Canada: The district council of Capital Regional District (CRD) says that it expects to resume sending biosolids to Lafarge Canada's Richmond cement plant in early June 2023. This follows a reported reduction in production at the unit in 2023 and 2022, according to the Times Colonist newspaper. The 1.1Mt/yr cement plant previously used biosolids supplied by the CRD as an alternative fuel in its cement production. However, during the current hiatus the biosolids have been sent to landfill instead.

The Richmond cement plant is the site of the CO₂MENT carbon capture and utilisation project. The project proceeded to its third phase, which consists of a capture capacity expansion and the installation of a liquefaction plant, in May 2023.

Finland: Finnsementti is carrying out upgrades to its two integrated cement plants as part of its sustainability targets to 2030. The subsidiary of Ireland-based CRH is installing new main burner equipment at its Lappeenranta plant with completion scheduled for mid-2023. The project is intended to allow the plant to increase its use of alternative fuels. The company’s Parainen plant is replacing its satellite coolers with a grate cooler with completion scheduled for the spring of 2024. This work is expected to decrease the plant’s emissions by 10%. Overall the group is preparing to decrease its CO₂ emissions by 30% by 2030 compared to 2021 levels.

US: Continental Cement has ordered a Fuelflex Pyrolyzer alternative fuels combustion system from Denmark-based FLSmidth for installation at its Davenport plant in Buffalo, Iowa. The supplier says that its product offers a lower capital expenditure compared to competing systems, can control NO_x emissions without the need for ammonia water and can be installed without a long shutdown period. This is the first commercial installation of the Fuelflex Pyrolyzer system following a pre-commercial installation at the Mannok cement plant in Northern Ireland, UK, in 2022.

David Loomes, the president of Continental Cement, said “We’re very excited about what the Fuelflex Pyrolyzer will do for our process.” He added, “We’re planning to achieve 55% fossil fuel replacement across the plant, utilising non-hazardous waste that would otherwise go to landfill or incinerators. The economic and environmental benefits of this technology are very significant and a key element of executing our carbon reduction commitment.” Continental Cement, a subsidiary of Summit Materials, has been incorporating waste materials as fuels for more than 30 years.

Jens Jonas Skov Larsen, Head of Capital Sales at FLSmidth, said “Mannok has called the Fuelflex Pyrolyzer a game-changer for the cement industry.” He continued, “This system effectively rearranges the order of the combustion process to make use of hot preheater meal, which is the heat source for the waste fuel pyrolysis. It’s a more efficient way of burning alternative fuels and it comes with a host of benefits, including reduced emissions and a more stable process.”

The installation at Davenport cement plant is expected to start operation in 2024. The full commercial launch for the system is scheduled by 2025. No value for the order has been disclosed.

Finland: Tana Oy has appointed Kalle Saarimaa as its chief executive officer with effect from 1 June 2023.

Saarimaa is currently working as the Senior Vice President for Circular Solutions at Fortum Oyj. However, he has been a member of the board of Tana Oy since 2021. Prior to working for Fortum Oyj he held posts with Ekokem and Walki Oy. He is also active in Finnish and European waste management organisations and as a board member of circular economy companies.

Tana sells products to the recycling and landfill sectors such as shredders, compactors, screeners, sifters and more.

Mexico: Cemex's waste management subsidiary Regenera has signed a deal with the municipal council of Huajuapan de León to receive the latter's sorted non-recyclable municipal solid waste (MSW). Under the deal, Regenera will receive up to 6000t/yr of MSW, which it will supply to Cemex's Tepeaca cement plant in Puebla.

India: Ambuja Cements has placed orders with equipment suppliers for an 8Mt/yr clinker capacity expansion across two of its cement plants. The plants in question are the 2.9Mt/yr Bhatapara cement plant in Chhattisgarh and the 4.5Mt/yr Maratha cement plant in Maharashtra. Ambuja Cements will also build 42MW-worth of waste heat recovery (WHR) power capacity. The new cement capacity will be able to operate on renewable energy and use 50% alternative fuel (AF). As such, upon completion of the project, the plants will together produce 14Mt/yr of Ambuja Cements' reduced-CO₂ Blended Green Cement. The producer will fund the work through internal accruals, and expects to complete it in May 2025.

CEO Ajay Kapur said "These brownfield expansion projects are part of our strategy to double our production capacity over the next five years from the current capacity of 67.5Mt/yr. Our ongoing investments in capacity expansion and sustainability will enable us to achieve our long-term objectives, as we remain committed to delivering sustainable growth and value to our stakeholders."

India: Nuvoco Vistas’ sales rose by 14% year-on-year during the 2023 financial year, to US$1.29bn. The group’s cement sales volumes were 18.8Mt, up by 5%. It recorded a profit after tax of US$1.95bn.

In 2023, Nuvoco Vistas achieved a cement alternative fuel (AF) substitution rate of 12%. Its emphasis on developing blended cements enabled it to achieve an industry-leading cement to clinker factor of 55%. It operations during the year relied on over 20% renewable energy.

India: ACC has blamed a drop in earnings in the fourth quarter of its financial year on higher fuel prices. Its earnings before interest, taxation, depreciation and amortisation (EBITDA) fell by 15% year-on-year to US$71.9m in the quarter that ended in March 2023 from US$64.7m in the same period in 2022. However, it said that fuel prices were expected to drop due to synergies with other subsidiaries within Adani Group. It is also working on reducing operational costs by reducing its clinker factor, logistics costs and growing sales of blended cement products. It added that it had reduced its kiln fuel cost by 10% in the fourth quarter by taking the measures mentioned above and by increasing its use of alternative fuels.

The company changed its financial year to one ending in March 2023 during the reporting period. Its calculated net revenue rose by 10% year-on-year to US$2.16bn for its 2023 financial year that ended on 31 March 2023 compared to US$1.97bn in the previous 12 months. Its cement and clinker sale volumes grew by 6% to 31Mt from 29Mt.

Ajay Kapur, the chief executive officer of ACC, said “Our transformation journey fuelled by sizeable operational efficiencies, improved synergies and business excellence has led to substantial improvement in our financial performance and overall business indicators. We have a detailed blueprint on each of the cost factors and initiatives to reduce and improve.”
