Centre Proposes Clearance Exemption For Cement Grinding Units

Move may aid Adani’s Rs 14 billion Kalyan cement project approval.

The Union Ministry of Environment, Forest and Climate Change has proposed to exempt standalone cement grinding units without captive power plants from the requirement of prior environmental clearance, according to a draft notification issued on 26 September.

If approved, the move could benefit the Adani Group’s proposed Rs 14 billion (Rs 1,400 crore) 6-million-tonne-per-annum cement grinding plant in Kalyan, part of the Mumbai Metropolitan Region. The plant, belonging to Ambuja Cement Ltd, an Adani Group company, has faced strong opposition from residents of Mohone and ten surrounding villages.

At a Maharashtra Pollution Control Board (MPCB) public hearing last month, citizens expressed concerns over potential health hazards and environmental risks from the project, questioning how such a large-scale industrial facility could be allowed in a densely populated area.

Locals highlighted the risk of emissions including particulate matter, sulphur dioxide, nitrogen dioxide, and carbon monoxide.

However, the ministry’s draft notification proposes that standalone cement grinding units — which do not carry out high-temperature “calcination” or “clinkerisation” processes — be exempted from detailed Environmental Impact Assessment (EIA) reports and public consultation requirements. The ministry argues that such units have a lower pollution potential compared to integrated cement plants but are still subjected to equally stringent compliance measures, resulting in disproportionate regulatory burdens.

Officials explained that these standalone facilities consume less energy and generate less waste, as they do not undertake the heating and chemical breakdown processes integral to full-scale cement manufacturing.

Furthermore, the draft encourages the use of green logistics, such as the transportation of raw materials and finished products through railways and electric vehicles. The Expert Appraisal Committee (EAC), after detailed deliberation, recommended the exemption to promote “environmental governance and green logistics.”

Sources said the Ambuja Cement plant, located near Ambivli railway station, is likely to rely on rail transport for raw materials, aligning with the EAC’s sustainability criteria.

The public has 60 days from the date of notification to submit comments or objections. Once finalised, the amendment will form part of the 2006 EIA notification that governs environmental clearance norms.

Subhash Patil, president of the Gramastha Mandal Mohone Koliwada — a local group opposing the project — said residents were unaware of the new proposal. “I don’t think it’s a good move by the government. We’ll review the notification and decide our next steps,” he said.

An MPCB official confirmed the ministry’s draft, stating that feedback will be reviewed before the final decision is taken.

According to the project summary, the proposed plant will occupy 26.13 hectares, with 9.67 hectares reserved for green belt development and 5.49 hectares for the grinding unit, storage, and packing facilities.

The project, planned on the former National Rayon Company (NRC) site in Ambivli near Titwala, will house a 6-million-tonne-per-annum grinding capacity. The NRC facility, established in 1945, ceased operations in 2006 and was acquired by the Adani Group through the National Company Law Tribunal (NCLT) in 2020 after a long-standing labour dispute.

The need of present time is stronger buildings, industrial or common utility buildings, such as Malls, Railway stations, hospitals, offices, bridges etc. For this, there is need of long durable, tough and stable concrete, which could stand under normal and seismic conditions. Tough railway bridges are required for bullet trains to pass without any damage. Railway tunnels, sea-links, coastal roads, bridges and multistorey buildings, are the need of the hour. The question comes, is the normal cement called OPC is sufficient to take care of such requirements or better combination of cements and sand mixtures is required?

Introduction

A good stable building structure can be made with a good quality of cement+sand+water system. Its quality can be enhanced by keeping the density of admixture higher (varies from 30 in normal buildings to bridges etc to 80). Further enhancement in the properties of various cements admixtures is made by adding several additives which give additional strength, waterproofing, flexibility etc. These are called construction chemicals…

The National Council for Cement and Building Materials (NCB) has signed a memorandum of understanding with a leading cement manufacturer to strengthen skill development and capacity building in the construction sector. The agreement was formalised at NCB premises in Ballabgarh and was signed by the Director General of NCB, Dr L. P. Singh, and the head of technical services at UltraTech Cement Limited, Er Rahul Goel. The collaboration seeks to bring institutional resources and industry expertise into a structured national training effort.

The partnership will deliver structured training and certification programmes across the country aimed at enhancing the capabilities of civil engineers, ready?mix concrete (RMC) professionals, contractors, construction workers and masons. Programme curricula will cover material quality testing, concrete mix proportioning, durability assessment and sustainable construction practices to support improved construction outcomes. Emphasis is to be placed on standardised assessment and certification to raise practice levels across diverse construction roles.

Practical learning elements will include workshops, site demonstrations, technical seminars and exposure visits to plants and RMC facilities to strengthen applied skills and on?site decision making. The Director General indicated confidence that a large number of professionals and workers would be trained over the next three to five years under the initiative. The partnership is designed to complement flagship government schemes such as the Skill India Mission and to align training outputs with national infrastructure priorities.

By combining the council’s technical mandate with industry experience, the initiative aims to develop a more skilled and quality?conscious workforce capable of meeting rising demand in infrastructure and housing. NCB will continue to coordinate programme delivery and quality assurance while industry partners provide practical exposure and technical inputs. The collaboration is expected to support long?term capacity building and more sustainable construction practices nationwide.

JSW Cement has strengthened its national presence by commencing production at its greenfield integrated cement plant in Nagaur, Rajasthan, marking its entry into the north Indian market.

With this commissioning, the company’s installed grinding capacity has increased to 24.1 MTPA, while total clinker capacity, including its joint venture operations, stands at 9.74 MTPA.

The Nagaur facility comprises a 3.30 MTPA clinkerisation unit and a 2.50 MTPA cement grinding unit, with an additional 1.00 MTPA grinding capacity currently under development. Strategically located, the plant is positioned to serve high-growth markets across Rajasthan, Haryana, Punjab and the NCR.

The project has been funded through a mix of equity and long-term debt, with Rs 800 crore allocated from IPO proceeds towards part-financing the unit.

Parth Jindal, Managing Director, JSW Cement, stated that the commissioning marks a key milestone in the company’s ambition to become a pan-India player. He added that the project was completed within 21 months and positions the company to achieve its targeted capacity of 41.85 MTPA by FY29.

Nilesh Narwekar, CEO, JSW Cement, highlighted that the expansion aligns with the company’s strategy to tap into rapidly growing northern markets driven by infrastructure development. He noted that the company remains focused on delivering high-quality, eco-friendly cement solutions while progressing towards its long-term capacity goal of 60 MTPA.

The Nagaur plant has been designed with sustainability features, including co-processing of alternative fuels and a 7 km overland belt conveyor for limestone transport to reduce road emissions. The facility will also incorporate a 16 MW Waste Heat Recovery System to improve energy efficiency and lower its carbon footprint.

JSW Cement, part of the JSW Group, operates across the building materials value chain and currently has eight plants across India, along with a clinker unit in the UAE through its joint venture.
