Iranian cement plants use mazut as fuel amid gas shortage
15 January 2024Iran: 70% of cement plants by capacity were reportedly using the low-quality heavy fuel oil mazut as cement fuel on 13 January 2024. Iranian Labour News Agency has reported that plants transitioned to the fuel from natural gas amid an on-going gas shortage. This has led to a rise in costs and increased pollution from cement plants.
Iran’s Cement Industry Employers’ Association said that the industry’s supply of natural gas has dropped to 7Mm3/yr, from 27M3/yr normally.
Germany: Rohrdorfer Zement has fired up a pilot clay tempering unit at its Rohrdorf cement plant in Bavaria. The project has received Euro8.65m in funding from the German Federal Ministry for Economic Affairs and Climate Action and the EU. It is one of a number of industrial projects under the EU’s Euro800bn NextGenerationEU post-Covid-19 economic recovery instrument. Sources of heat for the pilot unit at the Rohrdorf cement plant include waste heat from the plant’s clinker line. If the pilot succeeds, the introduction of tempered clay into cement production at the site will follow. This will entail the construction of an on-site full-scale clay tempering plant. Rohrdorfer Zement says that this would reduce the plant’s CO2 emissions by 16 – 18%, or by 30% if it achieves carbon neutral clay tempering through the use of green hydrogen.
Rohrdorfer’s dedicated Net Zero Emissions Labs team is working to turn the Rohrdorf cement plant carbon neutral by 2038. Other initiatives include the installation of carbon capture systems at the Rohrdorf plant and another in Austria, and participation in the H2-Reallabor Burghausen hydrogen partnership.
Regarding the latest pilot, Rohrdorf Net Zero Emissions Labs project leader Helmut Leibinger said “As a cement component, tempered clays make a significant contribution to CO2 mitigation. With the pilot project of process-integrated tempered clay, we are taking not just a step in our decarbonisation roadmap, but a leap.”
Holcim Deutschland upgrades Beckum cement plant
09 January 2024Germany: Holcim Deutschland has announced for the ‘most extensive’ modernisation of its Beckum cement plant to date. Local press has reported that the modernisation will commence with the installation of a Euro20m pendulum cooler to replace the plant’s existing tube cooler. The new cooler will reduce the plant’s CO2 emissions and make separated CO2 better suited for capture, according to the producer. The Beckum cement plant is the site of an on-going carbon capture trial.
General manager Jan Kristof Peters said “We want to implement all construction work as quickly as possible and with as little noise pollution as possible for the neighbourhood. As in previous years, we ask for our neighbourhood’s understanding.”
Saffron Growers Association accuses Kashmiri cement plants of causing dust pollution
09 January 2024India: The Saffron Growers Association (SGA) has said that cement plants in Kashmir are causing dust pollution, to which the association attributed the decline of the local saffron industry. Down to Earth News has reported that the SGA alleges that the state’s traditional crop has ceased to be profitable because of extra costs arising from the fall of dust during flowering season. The association added that pollutants such as nitrous oxides (NOx) and sulphur dioxide (SO2) can also affect saffron’s growth.
The SGA called on authorities to regulate the construction of cement plants and their emissions more closely.
Cementi Tojik disbands and shuts Dushanbe cement plant
02 January 2024Tajikistan: Cementi Tojik announced the closure of the 1.1Mt/yr Dushanbe cement plant and its disbandment as a company on 26 December 2023. Asia-PLUS News has reported the reason for the company’s departure from the industry as a government regulation issued in mid-2023, which ordered the closure of the plant due to ‘serious’ emissions violations.
École Polytechnique Fédérale de Lausanne recognised as Energy Transition Changemaker for LC3 limestone calcined clay cement project
19 December 2023Switzerland/UAE: The COP28 UAE Presidency named École Polytechnique Fédérale de Lausanne (EPFL) among its Energy Transition Changemakers in the Heavy Emitting Sectors category. EPFL won the prize for its LC3 limestone calcined clay cement, which replaces 50% of clinker content with calcined kaolinite clay and limestone. LC3 cement reduces CO2 emissions by 40% compared to ordinary Portland cement (OPC), and is a readily available solution that can be scaled worldwide. EPFL noted the special importance of LC3 cement for CO2 reduction efforts in developing countries, and sees it as having the potential to eliminate 500Mt/yr of global CO2 emissions by 2030. In a post to LinkedIn, the LC3 Project said that nine plants around the world currently produce LC3 cement, with a further 20 planned before 2025.
Reon Energy to build microgrid for Arabian Yemen Cement
18 December 2023Yemen: Pakistan-based Reon Energy has won a contract to build a microgrid equipped with a 13.5MW solar power plant and a 5.59MWh battery energy storage system for Arabian Yemen Cement. The energy storage system will employ Reon Energy’s SPARK Intelligent Energy Management product. The supplier said that the project aims to reduce energy costs by 20% and lower CO2 emissions from Arabian Yemen Cement’s operations.
Arabian Yemen Cement chief executive officer (CEO) Waheeb Al-Azab said "Our partnership with Reon Energy signifies a monumental stride towards sustainable energy practices, enabling us to harness solar power, significantly reduce our carbon footprint and optimise fuel efficiency in our operations."
Reon Energy CEO Mujtaba Khan said "This collaboration marks a significant step in our commitment to delivering practical, efficient solutions, tailored to industry-specific energy challenges. We look forward to driving positive change in the energy landscape of the cement industry with Arabian Yemen Cement."
China: China Resources Building Materials Technology (CRBMT) subsidiary Tianyang Cement has concluded a ‘full-process intelligent cement plant’ pilot at its 2.81Mt/yr Baise cement plant in Guangxi Province. Tianyang Cement said that the pilot entailed an upgrade that has more than doubled Baise cement plant’s production volumes and reduced its CO2 emissions per tonne of cement by 24%. Tianyang Cement says that automation has reduced the plant’s unplanned shutdowns by 56% and improved product quality.
CBR Cement, CCB and Holcim Belgique to halve CO2 emissions at four Wallonian cement plants
14 December 2023Belgium: The government of Wallonia and the European Commission’s Just Transition Fund (JTF) have awarded funding to CBR Cement, CCB and Holcim Belgique to support the reduction of CO2 emissions from Wallonia’s cement plants by 50%. The efforts will focus on renewable energy projects, including the construction of new waste heat recovery (WHR) systems. Alongside two steel plants, the companies will share Euro282m-worth of funding for projects across their four cement plants. The L’Echo newspaper has reported that Wallonia will contribute Euro169m, while the JTF will contribute the remaining Euro177m. The projected cost of planned decarbonisation projects in the Wallonian cement and steel industries is Euro346m. The proposed projects will increase the number of people employed across the sectors by 6.4% to 2773.
Neighbours of Lafarge Canada’s Exshaw cement plant launch lawsuit over alleged dust spills
12 December 2023Canada: Residents of Exshaw and Lac des Arcs, Alberta, near Lafarge Canada’s Exshaw cement plant, have filed a lawsuit over allegedly increasing dust emissions from the plant. Postmedia Breaking News has reported that law firm Napoli Shkolnik Canada said that dust spills occur ‘regularly.’ The plant’s operations allegedly also blacken snow on the ground in the area and have caused ‘severe’ odours and ‘violent’ tremors.
