Step Toward Air Pollution Control: MPCB Enforces Stricter Rules for Ready-Mix Concrete (RMC) Plants

Pune, 29th October 2025: In a move aimed at curbing rising air pollution levels, the Maharashtra Pollution Control Board (MPCB) has issued new and stringent guidelines for Ready-Mix Concrete (RMC) plants across the state. Environmentalists have welcomed the move, saying the revised measures could significantly reduce dust emissions and improve urban air quality. Currently, around 85 RMC plants operate in the Pune district.

“These scientific and strict measures were much needed to address a critical issue like air pollution. However, implementation must be equally rigorous. It’s not enough to introduce new rules — there must also be a firm policy on punitive action against RMC plants that fail to comply. Without proper enforcement, the intended benefits will not be achieved,” said Shweta Vernekar, Senior Project Associate at Parisar Sanstha.

The Bombay High Court had earlier taken suo motu cognizance of worsening air quality and registered a public interest litigation (PIL). During the hearings, the MPCB initiated several steps to improve air quality in the Mumbai Metropolitan Region (MMR). It was found that rapid urbanization and construction activities, including RMC operations, were major contributors to air pollution. Responding to these findings, the MPCB has now introduced comprehensive and stricter norms for the sector.

Under the new rules, all existing and upcoming RMC plants are required, within one month, to enclose their raw material handling areas, silos, conveyor belts, loading and unloading zones, and mixing units within a tin or metal-based “box structure.” The MPCB stated that this measure will help minimize the release of dust and fine particles, leading to cleaner air in nearby areas.

Additionally, existing commercial RMC plants must now furnish a bank guarantee ranging from ₹25 lakh to ₹50 lakh to ensure proper maintenance of pollution control systems. The board has also imposed tighter restrictions on plants located in residential zones.

Several RMC units have previously been flagged for violating MPCB norms, causing severe dust pollution and health issues for nearby residents. The particulate matter emitted from these plants has been linked to respiratory problems and other ailments. To safeguard public health, the new guidelines prohibit setting up any new commercial RMC plants within 200 meters of schools, colleges, hospitals with more than 50 beds, or court premises.

Environmental experts have lauded the MPCB’s decision, calling it a vital step toward cleaner air, but stressed that enforcement will be key to ensuring real change.
