India: Nuvoco Vistas recorded full-year consolidated sales of US$1.2bn in its 2022 financial year, up by 24% year-on-year. The group’s earnings before interest, taxation, depreciation and amortisation (EBITDA) remained level year-on-year at US$198m. Its profit after tax also remained level at US$4.12m.

The Pioneer newspaper has reported that Nuvoco Vistas’ Chittor cement plant achieved an alternative fuel (AF) substitution capacity of 23% during the 2022 financial year. The group says that it remains focused on increasing its proportion of blended cement products, in addition to AF and waste heat recovery (WHR) projects.

India: Holcim has agreed to sell its Indian business to industry, energy and ports conglomerate Adani Group for US$6.37bn. The assets consist of a 63% stake in Ambuja Cement, which in turn owns 50% of ACC, and a 4.5% direct stake in ACC.

ACC and Ambuja Cement employ 10,700 people and operate 31 cement plants in India. The deal will make Adani Group India’s second-largest cement producer.

Chair Gautam Adani said "With Holcim's global leadership in sustainability, we are acquiring some of the most efficient building materials operations in India, powered with clean technologies like heat recovery systems. We recognise that Ambuja and ACC operations are energy intensive and therefore, when combined with our renewable power generation capabilities, we gain a big head start in the decarbonisation journey that is a must for Indian industry."

Holcim says that its focus is now on expanding its solutions and products business. Reuters News has reported that the group plans to put the proceeds of the assets’ sale towards lower-carbon acquisitions. Its Indian operations contributed 26% of group CO₂ emissions.

Chief executive officer Jan Jenisch said "We will always make cement, but we will decarbonise cement.” He added “We are happy to build up other segments like building solutions and products."

China: Huaxin Cement says it has been approved for a US$5.8m preferential carbon emission reduction loan. It is the first such finance arrangement in the local cement sector. The People's Bank of China established a carbon emission reduction support tool in November 2021 to guide financial institutions to increase green and low-carbon credit support. Huaxin Cement’s Huangshi subsidiary put together its application based around a waste heat recovery project. It then worked with the Bank of Communications and the People's Bank of China. The cement producer says that its other subsidiaries are now working on similar applications.

India: ACC’s earnings before taxation, interest, depreciation and amortisation (EBTIDA) fell by 26% year-on-year to US$83.1m in the first quarter of 2022 from US$113m in the same period in 2021. Net sales rose by 3% to US$566m from US$552m. Sales volumes of cement dropped by 3% to 7.71Mt but volumes of ready-mixed concrete grew by 5% to 0.87Mm³. The subsidiary of Ambuja Cement and Holcim said that its costs had been negatively affected by a global rise in fuel costs caused by ‘geopolitical events.’

The cement producer said that its new integrated plant at Ametha in Madhya Pradesh is scheduled to be commissioned in the fourth quarter of 2022.

India: Shree Digvijay Cement has executed a share purchase agreement to acquire a 27% stake in a hybrid wind and solar power project from Trinethra Renewable Energy, a power producer, and Continuum Green Energy. It will spend US$1m on the deal, implying a value of US$0.13m/MW. The total installed capacity of the project is 8.1MW.

The hybrid power contract will generate about 37% of total power needed by the plant. When combined with the plant’s waste heat recovery (WHR) system, it will constitute over 65% of the total power needs of the company, representing considerable savings in the cost of power and an improved environment footprint.

India: Shiva Cement's board of directors has approved the launch of a shareholders' vote over plans to increase its Odisha cement plant's capacity by 2Mt/yr.

The company has received Ministry of Environment, Forest and Climate Change approval for all of the plans.
