Holcim invests in new energy projects at Mannersdorf plant
01 October 2024Austria: Holcim is set to significantly reduce its carbon footprint with the installation of a new clinker cooler system and a large-scale photovoltaic system at its Mannersdorf cement plant. The clinker cooler project is valued at approximately €10m, and aims to cut heat consumption and reduce CO₂ emissions by 18,000t/yr. Completion is expected in early 2025. The solar project will be fully operational by 2025, and will cover approximately 15% of the plant’s energy needs and reduce CO₂ emissions by an additional 12,700t/yr. 2.7MW of solar panels were erected at the site of the former chimney on the plant’s premises.
Plant manager Helmut Reiterer said "Sustainability requires decarbonisation, i.e. continuously reducing the CO₂ emissions from our production activities. We are placing an investment focus on energy-efficient production by modernising our machinery, but also on expanding green energy."
Mombasa Cement to build new power plant
21 August 2024Kenya: Mombasa Cement will build a 20MW power plant at its Vipingo plant in Kilifi County, to help reduce energy costs. The US$19.4m project will generate 10MW of electricity using a waste heat recovery system and 10MW from solid fuels. The waste heat will be recovered from flue gases emitted during cement production. The plant has two clinker production lines. The power generated will be used onsite to support cement production.
First Gen to supply geothermal energy to Holcim Philippines
20 August 2024Philippines: First Gen will supply electricity from geothermal sources to Holcim Philippines plants in Mindanao. Under the agreement, First Gen subsidiary Energy Development will provide 22% of the energy needs for Holcim's manufacturing facilities in Bunawan, Davao City, and Lugait, Misamis Oriental. This partnership is enabled by the Mindanao introduction of the retail competition and open access programme, allowing significant power consumers to select their electricity suppliers. Earlier in August 2024, Holcim announced an electricity supply agreement with Alsons Power to supply 80% of the energy needs for the two facilities.
First Gen president and chief operating officer Francis Giles Puno said "We are pleased to partner with Holcim Philippines to grow viably while decarbonising. It's not an easy journey to decarbonise and provide for a regenerative future. This requires collaboration not just through supplying power, but also through solutions that maximise and optimise electricity requirements and working to find a pathway towards net zero."
Mexico: A second industrial byproducts processing line has been inaugurated at the Cemento Cruz Azul plant in Tepezalá, Aguascalientes. The new facility, which cost US$8.5m, will create 100 jobs and convert over 66,000t/yr of post-consumer materials into energy for the cement plant's processes.
Víctor Manuel Velázquez Rangel, president of the board of directors of Cooperativa Cruz Azul, said "This is the result of joint work, teamwork and a shared vision with the State Government, which has always been concerned about the carbon footprint, sustainability and the environment. With this project we leave testimony of our great commitment and demonstrate that innovation and technology can go hand in hand with the preservation of the environment."
Philippines: Alsons Power has signed a retail electricity supply agreement with Holcim Philippines, committing to provide 80% of the energy needs for Holcim's facilities in Davao and Lugait, Misamis Oriental.
Edwin Villas, senior vice president and head of supply chain at Holcim Philippines, said “We are confident that our partnership with Alsons Power will help us achieve our business goals and sustainability aspirations. Partnering with Alsons Power is the right choice given its strong and trusted reputation for providing reliable and affordable electricity in its three decades in the energy industry.”
China: The National Development and Reform Commission, along with other government departments, has launched the Special Action Plan for Energy Conservation and CO2 Reduction in the Cement Industry. The plan aims to cap clinker capacity at 1.8Bnt/yr by 2026, with 30% of it above the national energy efficiency benchmark level. This will reduce energy consumption per tonne by 3.7% from 2020 levels. The plan will eliminate 13Mt of CO2 emissions and 5Mt of coal consumption in 2024 – 2025.
Thailand: Siam Cement Group (SCG) has begun construction of a commercial heat battery supplied by Rondo Energy at its cement plant in Saraburi Province. It will be the first heat battery in Southeast Asia and the first heat battery deployed at a cement plant, according to the company. The project is a collaboration between Rondo Energy and SCG Cleanergy, a wholly owned subsidiary of SCG. Rondo Heat Batteries capture intermittent electricity and store energy as high temperature heat in bricks, to deliver continuous industrial heat and power on demand. This installation will convert local solar power into continuous zero-carbon heat and power for cement production.
President of Rondo Energy, Eric Trusiewicz, said "Electrification of cement production requires a large-scale and low-cost energy storage solution, as renewables are not available 24/7 but cement production needs to be."
Spain: The Spanish cement manufacturers' association, Oficemen, and Siemens Energy have signed a two-year collaboration agreement to develop decarbonisation techniques and solutions for Spain's cement industry. The agreement was signed by Siemens Energy's Industrial Sales Director for Southwest Europe, Angel Cillerruelo, and Oficemen's General Director, Aniceto Zaragoza.
Zaragoza said "The Spanish cement industry's commitment to climate neutrality by 2050, outlined in our roadmap, includes exploring the most effective levers for emission reduction, such as the decarbonisation of energy sources or the comprehensive energy management of industrial processes."
India: Orient Cement has successfully commissioned Phase 2 of the new waste heat recovery (WHR) plant at its Chittapur cement plant in Karnataka. Reuters has reported that the new phase raises WHR power capacity at the plant to 10.1MW.
Thailand: Siam Cement Group (SCG) reported first-quarter sales of US$3.36bn in 2024, down by 3% year-on-year. The group partly attributed this to a decline in its cement volumes. Nonetheless, group earnings before interest, taxation, depreciation and amortisation (EBITDA) rose by 4% to US$341m. Special items in the group’s first-quarter 2023 results precipitated an 85% year-on-year decline in net income to US$65.5m from US$446m.
SCG recorded first-quarter CO2 emissions of 5.99Mt, outstripping the Science-Based Targets Initiative (SBTi)’s recommendation of a 2.5% annual reduction. It relied on 47% renewable energy sources in its cement production.
