India: Tamil Nadu will host one of five national carbon capture and utilisation (CCU) testbeds aimed at lowering CO₂ emissions in the cement sector in a step towards the country’s 2070 net-zero target, according to The New Indian Express newspaper. The testbed will be located at UltraTech Cement’s Reddipalayam plant in Ariyalur district, supported by the Indian Institute of Technology Madras and Birla Institute of Technology and Science Pilani. The project is part of a Department of Science and Technology (DST) programme, which will trial an oxygen-enriched kiln system capturing up to 2t/day of CO₂ for mineralisation into concrete products. Other CCU testbeds are being established in Rajasthan, Odisha and Andhra Pradesh, with JK Cement and Dalmia Cement involved.

Union Minister for Science and Technology and Earth Sciences Jitendra Singh said the DST was currently processing financial sanctions for the projects, and full-scale implementation is expected in 2025.

Kenya: Ndovu Cement, owned by Karsan Ramji & Sons, will build a 600t/day greenfield clinker plant and a limestone quarry in Mukawa, Kajiado County, according to regulatory filings. The project has already secured approval from the National Environment Management Authority. The company said the limestone quarry will ensure a reliable supply of 900t/day of limestone.

The facility is expected to reduce reliance on imports following a 17.5% levy on clinker imports introduced in July 2023, according to the Business Daily Africa newspaper. The measure was aimed at boosting local production and creating jobs, but has since led to a drop in cement consumption due to price increases and a fall in imports. Kenya-based cement producers had reportedly opposed an attempt to increase import duty on clinker, instead requesting a grace period of four years, until 2026, to allow them to build their own clinker production facilities.

Karsan began as a quarry operator in Kitengela, Kilifi and Nakuru, before beginning cement production in 2015 and launching Ndovu Cement in June 2015.

Papua New Guinea: Mayur Resources has rebranded as Pacific Lime and Cement to reflect its transition from a resource developer to an integrated supplier of lime, cement and building products. The country’s demand is projected to grow in 2026, according to local press reports. The decision also comes amid the government’s target of reducing cement imports.

Managing director Paul Mulder said “Our rebrand to Pacific Lime and Cement reflects our transformation into an integrated industrial materials company focused on nation-building in Papua New Guinea. The new name positions us clearly in the market as a supplier of cement, quicklime and processed building products.”

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.”
