India’s largest aluminium manufacturer, Vedanta Aluminium, has delivered its first rake of 4,000 tonnes of fly-ash from its Jharsuguda facility to one of Holcim India’s ACC Cement Chaibasa Cement Works for the manufacturing of low-carbon cement.

This programme is one of Vedanta Jharsuguda’s waste-to-wealth imperatives, and it guarantees that an industrial by-product like fly-ash is used profitably in circular economy channels.

Fly-ash is a by-product of coal-fired thermal power generation and is used to meet the energy needs of Vedanta’s Jharsuguda aluminium smelters.

Fly-intrinsic ash’s properties may be used to improve product quality while also conserving energy, water, and other critical resources and lowering the industry’s carbon impact.

It offers considerable cost and energy savings as a large-scale industrial waste. Every tonne of fly-ash used in cement production may help save 700 kg to 800 kg of carbon emissions, 4.2 million kilojoules of energy, and 341 litres of water.

To identify new methods to use this industrial byproduct, the company holds workshops around the country with international specialists to raise awareness about the advantages of employing fly-ash in a cement building.

Vedanta has been supplying fly-ash to several cement firms in the Jharsuguda area. Vedanta Jharsuguda delivered 190,000 tonnes of fly-ash to local cement factories and 60,000 tonnes to local brick-making Micro, Small & Medium Enterprises (MSMEs) in fiscal year (FY) 2022.

In addition, the firm has formed a long-term relationship with India’s National Highways Authority (NHAI) to develop greener roads using fly-ash. The company has achieved the greatest ever fly-ash usage this year as a result of its consistent efforts in this regard.

The decision to ship fly ash via rail is to the company’s ambition of meeting its environmental sustainability goals, with the ultimate goal of becoming carbon neutral by 2050.

Niraj Kumar Bansal, Vice President and Head-India Raw Materials & Inward Logistics ? Supply Chain; ACC & Ambuja Cements Ltd (Holcim-India), told the media that Holcim India’s (ACC & Ambuja) partnership with Vedanta for fly ash evacuation is in line with their organisation’s endeavours to promote a circular economy, bringing in sustainable growth.

He said that the cement industry uses fly-ash for blending purposes, and it offers several advantages in terms of cost, quality, and workability, as well as increased strength.

Bansal said that the cement industry should be keen on the prospect of using this industrial byproduct to its benefit.

Towards Mega Batching

Optimised batching can drive overall efficiencies in large projects.

India’s pace of infrastructure development is pushing the construction sector to work at a significantly higher scale than previously. Tight deadlines necessitate eliminating concreting delays, especially in large and mega projects, which, in turn, imply installing the right batching plant and ensuring batching is efficient. CW explores these steps as well as the gaps in India’s batching plant market.

Choose well

Large-scale infrastructure and building projects typically involve concrete consumption exceeding 30,000-50,000 cum per annum or demand continuous, high-volume pours within compressed timelines, according to Rahul R Wadhai, DGM – Quality, Tata Projects.

Considering the daily need for concrete, “large-scale concreting involves pouring more than 1,000–2,000 cum per day while mega projects involve more than 3,000 cum per day,” says Satish R Vachhani, Advanced Concrete & Construction Consultant…

Andhra Offers Discom Licences To Private Firms Outside Power Sector

Policy allows firms over 300 MW to seek distribution licences

The Andhra Pradesh government will allow private firms that require more than 300 megawatt (MW) of power to apply for distribution licences, making the state the first to extend such licences beyond the power sector. The policy targets information technology, pharmaceuticals, steel and data centres and aims to reduce reliance on state utilities as demand rises for artificial intelligence infrastructure.

Approved applicants will be able to procure electricity directly from generators through power purchase agreements, a change officials said will create more competitive tariffs and reduce supply risk. Licence holders will use the Andhra Pradesh Transmission Company (APTRANSCO) network on payment of charges and will not need a separate distribution network initially.

Licences will be granted under the Electricity Act, 2003 framework, with the Central and State electricity regulators retaining authority over terms and approvals. The recent Electricity (Amendment) Bill, 2025 sought to lower entry barriers, enable network sharing and encourage competition, while the state commission will set floor and ceiling tariffs where multiple discoms operate.

Industry players and original equipment manufacturers welcomed the policy, saying competitive supply is vital for large data centre investments. Major projects and partnerships such as those involving Adani and Google, Brookfield and Reliance, and Meta and Sify Technologies are expected to benefit as capacity expands in the state.

Analysts noted India’s data centre capacity is forecast to reach 10 gigawatts (GW) by 2030 and cited International Energy Agency estimates that global data centre electricity consumption could approach 945 terawatt hours by the same year. A one GW data centre needs an equivalent power allocation and one point five times the water, which authorities equated to 150 billion litres (150 bn litres).

Advisers warned that distribution licences will require close regulation and monitoring to prevent misuse and to ensure tariffs and supply obligations are met. Officials said the policy aims to balance investor requirements with regulatory oversight and could serve as a model for other states.
