Germany: Holcim, E.ON Energy Infrastructure Solutions and Orcan Energy have launched a large-scale waste heat recovery project at Holcim’s Dotternhausen cement plant to capture 10MW of unused heat from kiln exhaust gases. The recovered heat will supply internal processes, potential district heating networks and power generation via Orcan Energy’s eP1000 Organic Rankine Cycle (ORC) system. E.ON is responsible for the planning, construction, financing operation and maintenance of the plant as part of an Energy-as-a-Service model. This is intended to present no initial investment costs for Holcim.

Holcim South Germany plant manager Dieter Schillo said “This project marks an important milestone on our path to decarbonising cement production. The smart use of industrial waste heat not only reduces our Scope 2 emissions, but also strengthens our role as a pioneer in sustainable building materials.”

China: NovaAlgoma Cement Carriers (NACC) has placed another order for a HeatPower 300 waste heat recovery system from Climeon on a second cement carrier, to be built at Zhejiang Xinle Shipbuilding Co. and delivered in 2027.

The 38,000t vessel will run exclusively on green methanol and is expected to cut CO₂ emissions by over 60% compared to conventional vessels, reportedly avoiding around 180,000t of CO₂ emissions over 10 years. The HeatPower 300 will generate up to 300kW of carbon-free electricity from engine cooling water and exhaust gases.

India: Wonder Cement’s managing director Kiran Patil led the inauguration of Line 5 at the Nimbahera plant in Rajasthan on 7 May 2025, according to a social media post by the producer. The project increased the producer’s clinker capacity by 2.8Mt/yr to 13.35Mt/yr and cement capacity by 2.5Mt/yr to 21.5Mt/yr. The company partnered with APBCO on the expansion, which also includes a 12MW waste heat recovery system to increase energy efficiency.

Oman: Raysut Cement is reactivating a partnership with China's Sinoma Overseas Development to launch Oman's first waste heat recovery (WHR) power plant at its Salalah site, according to the Oman Daily Observer. The groundwork for the 9MW facility was originally laid in 2018. Once operational, the facility is expected to reduce the plant’s reliance on national grid power by up to 30% and reduce CO₂ emissions by more than 50,000t/yr. Engineering design and site preparations are expected to be revisited before the end of 2025.

Türkiye: TSKB (Industrial Development Bank of Türkiye) has signed a €75m investment loan agreement with Oyak Cement to fund renewable energy and waste heat recovery (WHR) projects. The funding will support the construction of a 115MW solar power plant in Beypazarı, Ankara, and waste heat recovery facilities at the Ankara, Adana and Mardin cement plants.

Oyak Cement general manager Murat Sela said “We have accelerated our investments for the Beypazarı solar power plant, as well as the WHR facility investments with a total installed capacity of 13.5 MW at our Adana, Ankara and Mardin plants. We expect these investments to help generate 237,000MW/yr of energy, while increasing the total renewable energy utilisation rate at our plants from 9% to 30%.”

Türkiye: Medcem has completed testing of its new waste heat recovery (WHR) facility, which will recover 25% of the energy demand of the plant’s second rotary kiln line commissioned in 2024.

The 9.6MW facility uses an organic rankine cycle (ORC) system to generate electricity from a single heat source. The company says that this will lead to significant cost savings in energy expenses while also reducing CO₂ emissions.

Vietnam: Xuan Son Group held the launch ceremony for Xuan Son Cement at the Xuan Son cement plant in Hoa Binh province on 21 February 2025. The plant spans 40 hectares, with a US$196m investment and a production capacity of 3.5Mt/yr. The plant integrates Polysius grinding technology, Flender transmission systems, Haver & Boecker automated packaging technology and electrical equipment and motors from Pfeiffer, Vacuum and ABB. Heat consumption is below 680kCal/kg of clinker, and electricity consumption is under 71kW/t of cement, according to the company. The plant uses refuse-derived fuel in the kiln, as well as waste heat recovery to reduce its reliance on fossil fuels. It aims for zero NO_x and CO₂ emissions.

India: Dalmia Cement (Bharat) plans to expand its cement plant in Mylavaram, Andhra Pradesh. The producer will invest US$321m to to more than double the plant’s clinker capacity from 4.6Mt/yr to 12.6Mt/yr, its cement grinding capacity from 2.6Mt/yr to 7.6Mt/yr and its waste heat recovery capacity from 12MW to 28MW.

The Andhra Pradesh Pollution Control Board will hold a public hearing on 27 March 2025 over the plans, the New Indian Express newspaper has reported. Local residents have raised allegedly ‘unaddressed’ issues, including disruptions to watercourses, increased dust pollution and possible structural damage from increased blasting.

India: Star Cement has successfully commissioned a 7MW air-quenched cooler waste heat boiler at its newly operational cement plant in Lumshnong, Meghalaya. increases the plant’s total waste heat recovery (WHR) capacity to 19MW. The WHR project aims to improve operational efficiency and reduce environmental impact.

Malaysia: Cahya Mata Cement will build a second line at its Mambong facility in Kuching to increase cement production and support Sarawak's infrastructure development. Construction is expected to take 24 months, with expected completion in March 2027.

The project will add 6000t/day of clinker capacity, raising output to 1.92Mt/yr. This will enable the company to become self-sufficient in its clinker supply and therefore eliminate the need for imports.

The company signed a technical consulting agreement with Sinoma Industry Engineering in November 2023 to design and construct the new production line. It will feature a waste heat recovery system, generating up to 6MW of power, alongside a dust filter designed to cut emissions to half of the current regulatory limit, according to the New Straits Times. The new line will also use locally-sourced alternative raw materials to reduce its reliance on fossil fuels.

Cahya Mata Cement acting division head Choong Ju Tang said "Once the project is approved and construction is completed, Cahya Mata Cement will be well-positioned to meet the construction industry's demand.”
