Sweden/India: Cemvision has received a grant from the Swedish Energy Agency to conduct a joint feasibility study with Tata Steel to convert basic oxygen furnace (BOF) and electric arc furnace (EAF) slags into feedstock for near-zero-CO₂ cement. The 10-12-month study will assess the technical and economic viability of a scalable slag valorisation model, ahead of a planned demonstration facility at Tata Steel’s site.

Cemvision CEO Oscar Hållén said “Being able to, at scale, turn environmental liabilities into valuable resources is exactly the kind of climate innovation heavy industry needs. In partnership with Tata Steel, we hope to show how steel slag can become a cornerstone in near-zero CO₂ cement, while metals are recovered and returned to steel production.”

The project is part of the India-Sweden Industry Transition Partnership (ITP), announced during Cop30 in Belém, Brazil. Tata Steel also received a grant from India’s Department of Science and Technology, with additional partners including IIT ISM Dhanbad and JK Cement.

India: Heidelberg Cement India has signed a contract to establish a cement plant at the Sant Singaji thermal power plant in Dogalia, Madhya Pradesh. The company will receive around 7ha of land for the project. The plant will produce between 150,000-200,000t/yr of cement using sludge generated from coal-fired power production, previously stored in dams. Construction is set to begin by the end of 2025 and is expected to complete in around 18 months.

South Korea: Cement exports are expected to reach 4.5Mt in 2025, up by 52% year-on-year, according to the Korea Cement Association, as producers seek to offset weak domestic demand and rising raw material costs. Domestic shipments are projected to fall by 16.5% to 36.5Mt, the lowest level in 34 years.

Despite high transport costs and limited profitability, producers including Ssangyong C&E, Halla Cement and SAMPYO Cement are increasing exports to cover fixed costs and maintain kiln operations to retain carbon emission allowances.

A cement industry official said “The domestic economy is as bad as during the global financial crisis, but we cannot stop the plants, so we are sending the cement piling up overseas. On top of that, we need to keep the plant kilns running to maintain a minimum allocation of carbon emission allowances, so the goal is also to secure at least fixed costs.”

Another official said “Ssangyong C&E, Halla Cement and SAMPYO Cement have plants on the coast, so their transportation expenses are lower than those of corporations located inland. For inland companies, transportation costs double when you add ocean freight to land shipping, so it is difficult even to choose exports as a stopgap measure.”

Halla Cement increased exports by 63% year-on-year, expanding sales beyond Latin America into African markets including Cameroon and Guinea. SAMPYO Cement also signed new export contracts with South America in the second quarter of 2025. The Korea Cement Association forecasts 2026 demand will fall further to 36Mt, down by 1.3% from 2025, citing continued stagnation in the domestic construction sector.

Malawi: Huaxin Building Materials Group and its subsidiary Portland Cement Malawi have commissioned a US$100m integrated cement plant in Balaka, 215km south of the capital Lilongwe. The factory is expected to produce 800,000t/yr of cement and reduce Malawi’s dependence on imported clinker and cement. Minister of Finance Joseph Mwanamvekha, who attended the inauguration ceremony, said the project aligns with the Malawi 2063 Agenda by supporting infrastructure and economic resilience.

Chinese Ambassador to Malawi Lu Xu said “The plant helps to address the current challenges by saving US$50m in foreign exchange expenditure annually, and generate US$15m in foreign exchange income.” She added that it is the largest manufacturing investment by a Chinese firm in Malawi and will create jobs, boost economic output and strengthen local industrial chains.
