Oman: Raysut Cement Company has launched a programme to recycle industrial byproducts for use as alternative fuel in cement production and electricity generation, to align with Oman's goal of net zero emissions by 2050.

Hilal bin Saif Al-Dhamri, Acting CEO of Raysut Cement, said "We use secondary industrial materials resulting from production processes across various industries. These are recycled in cement manufacturing and are categorised into two types: one that can be reused as an alternative fuel in plants, the other is used as a partial replacement to the main raw materials leveraged for cement production.” He added "We implemented a project to reuse exhaust heat and convert it to electrical energy at the Raysut Cement plant in Salalah. This innovative approach permits the plant to generate approximately 30% of its electrical energy, by reducing around 50,000t/yr of CO₂. As a result, the Salalah Raysut Cement plant stands out as environmentally friendly, distinguished by its capability to provide clean energy for cement production."

Al-Dhamri also noted that the company was able to enhance the efficiency of its Salalah plant through this programme, by reducing the clinker content while improving the performance of cement in concrete. This has reportedly contributed to a CO₂ emissions reduction of around 18% compared to ordinary cement.

Türkiye: IFC has provided a US$70m 'green' loan to Çimsa to support its decarbonisation efforts, according to a press release from the IFC. The investment will fund energy efficiency projects, modernisation and the installation of solar photovoltaic panels. Expected outcomes include a 10% reduction in greenhouse gas emissions and increasing renewable energy usage to 20% by 2025. IFC's Cement Decarbonisation Tool Advisory Service will also assist Çimsa in identifying operational enhancements and further investments for achieving its sustainability goals.

North Korea: State-owned Sunchon Cement has completed an upgrade to its cement plant in Sunch'ŏn-shi, P’yŏngan-namdo Province, Korea News has reported. The upgrade included the installation of real-time monitoring equipment in the plant’s raw materials conveying system. The company says that this will help to increase the plant’s efficiency. It also fitted new crushers and vibrating feeders.

Saudi Arabia: China National Building Material (CNBM) subsidiary Sinoma CDI has won a US$6m contract to upgrade cement and raw materials conveyors at Riyadh Cement Company’s Riyadh cement plant. The producer has opted for elevator conveyors for mechanical transportation, in place of its existing pneumatic conveyors. It expects this to increase energy efficiency and reduce necessary maintenance. The project is due for delivery in early 2025.

Riyadh Cement Company CEO Shoeil Al-Ayed said that the project aligns with the producer’s strategic energy reduction initiatives.

Brazil: Votorantim Cimentos plans to invest US$1bn in expanding its Brazilian operations in the period up to the end of 2028. US$304m-worth of the investments are already underway at the start of 2024. Reuters has reported that the investments include cement plant projects to raise Votorantim Cimentos’ Brazilian cement production capacity by 8.8% to 37Mt/yr. These include a US$162m investment in a 20% capacity expansion to its Votorantim cement plant and a US$60.8m, 1Mt/yr expansion to its Salto de Pirapora plant. Further aims are to ensure structural competitiveness, raise energy efficiency and digitise operations, including applying artificial intelligence (AI) to freight. The producer expects its earnings before interest, taxation, depreciation, and amortization (EBITDA) to eventually rise by US$263/yr between 2023 and 2028 as a result.

Philippines: Filinvest-ENGIE Renewable Energy Enterprise (FREE) has won a contract with Cemex Philippines for the construction of a 10.1MW solar power plant. The Business Mirror newspaper has reported that the plant is comprised of a ground-mounted array of solar panels at Cemex Philippines’ Apo cement plant in Cebu. The solar power plant will eliminate 10,000t/yr of CO₂ from the Cebu cement plant’s emissions. Additionally, the producer has signed a memorandum of understanding (MoU) with FREE for future collaborations on renewable energy and efficiency-increasing projects around the nearby city of Naga.

Cemex Philippines president and CEO Luis Franco said “This solar energy partnership is another milestone under Cemex’s Future in Action programme, as we progress closer to our goal of reducing Scope 2 CO₂ emissions to less than 24kg/t of cementitious product by 2030.” He added “We are proud to partner with FREE, a company that shares our vision to address climate change through sustainable projects. This is a win not only for Cemex, but also for the planet as we take concrete steps in making renewable energy the future of the industry.”

Romania: Holcim Romania has successfully upgraded pyroprocessing and cement grinding equipment at its Câmpulung cement plant in Argeș County. Germany-based KHD Humboldt Wedag supplied equipment for the upgrade. For the plant’s pyroprocessing line, this included a downcomer duct, water injection system and induced draught fan, as well as an upgrade to the clinker cooler. Meanwhile, the grinding line has received a new SKS Z 2500 dynamic separator, cyclones, process ducts and separator fan. The supplier says that the upgrade has increased the Câmpulung plant’s clinker capacity and the efficiency of its operations. The work took 14 months to complete from the signing of the contract in mid-2023.

Croatia: Nexe Group has completed a US$3.3m upgrade to its Našice cement plant. SeeNews has reported that the project consisted of efficiency-increasing upgrades to the plant and other buildings at the site, and the construction of a solar power plant. The producer says that this will reduce the 600,000t/yr-capacity cement plant’s total energy consumption by 1.56GWh/yr.

The Našice cement plant is the site of an on-going expansion and carbon capture system installation project.

Thailand: China-based intelligent dumptruck supplier Waytous has partnered with Siam Cement Group (SCG), as well as Thailand Advanced Info Service, Huawei, and Zhengzhou Yutong Mining Equipment, to develop full-scope automated operating systems for limestone mines. SCG will host a study at its Saraburi limestone mine in Central Thailand. The study will use Waytous’ driverless vehicles, supported by 5G, AI, cloud computing and new battery technologies.

Waytous CEO Chen Long "We've carried out two phases of unmanned mining research for this project and found the most comprehensive, efficient, and effective unmanned solution for cement mines in Saraburi.”

India: A report by the Council on Energy, Environment and Water (CEEW), funded by power provider BP, has estimated that India’s cement and steel sectors will require capital expenditure (CAPEX) investments of US$627bn in order to reach net zero CO₂ emissions. The report stated that waste heat recovery (WHR) and other efficiency-enhancing upgrades to cement plants can immediately reduce the industry’s emissions by 32%.

United News of India has reported that CEEW CEO Arunabha Ghosh said "Incentivising renewable energy will play a pivotal role in decarbonisation, through lower or no transmission charges at central and state levels. The government of India should develop a policy for and expedite the establishment of a carbon capture, utilisation and storage ecosystem to abate more than half of the emissions from the existing steel and cement plants.” Ghosh added “Since hydrogen will play a key role in its implementation, the next phase of the National Green Hydrogen Mission should focus on this agenda."
