Mumbai’s civic body has launched a fresh push to get large housing societies and commercial complexes to treat their own garbage instead of sending it to the city’s overflowing landfills. The Brihanmumbai Municipal Corporation (BMC) issued a call on August 1 inviting private agencies to help these properties set up on-site waste processing, backed by a property tax rebate of up to 15 percent, according to the Free Press Journal.

Who this targets

The scheme applies to what the BMC calls Bulk Waste Generators (BWGs): housing societies, commercial establishments, hospitals and institutions with a built-up area over 20,000 square metres, or that generate more than 100 kg of wet waste a day. The rules were framed under the state’s Solid Waste Management Rules, 2026, and follow directions from the Bombay High Court to cut the tonnage of garbage trucked out to landfill sites each day, as Down To Earth has reported.

The 15 percent rebate on the general property tax component breaks into three slices of 5 percent each: for composting wet waste on-site, for routing dry waste to authorised recyclers, and for reusing rainwater or treated grey water within the premises. Properties must register and keep their data updated on the BMC’s MyWaste portal to claim it.

Why uptake has been slow

The numbers show why the BMC is intensifying the drive rather than declaring it done. Of roughly 3,177 identified bulk generators citywide, about 2,025 have registered on the MyWaste portal, but only 513 have set aside space for processing units. As of June 2026, just 347 of 2,749 eligible properties, about 13 percent, had claimed the rebate at all. Space constraints in older buildings, the upfront cost of composting or biogas units, and simple inertia around segregation discipline are the usual reasons cited by civic officials and waste consultants for such gaps.

To close it, the BMC is now inviting empanelled agencies to handle the entire process for societies that opt in — site assessment, choosing the right technology, installation, operation, staff training, statutory compliance, and tie-ups with dry-waste recyclers — so that buildings don’t have to figure it out themselves. Only technologies that clear BMC’s technical evaluation will be allowed, according to a civic official cited by the Free Press Journal.

What it means for residents

For eligible housing societies, this is a direct trade: invest in a composting or waste-treatment setup, and recover part of the cost through a recurring tax break rather than a one-time subsidy. For the wider city, less wet waste headed to landfill sites means slower growth of Mumbai’s already-strained dumping grounds and marginally less diesel burned trucking garbage across the city daily. Municipal Commissioner Ashwini Bhide has also ordered stepped-up CCTV monitoring and weekly reviews of illegal dumping spots, signalling the civic body wants both a carrot for compliant societies and closer scrutiny of those that keep dumping unsegregated waste on the street.

Outlook

Whether this round of agency empanelment moves the adoption number past 13 percent depends on how quickly BMC can onboard credible agencies, and how many societies find the economics of rebate savings against setup and running costs worth the effort. Residents in eligible buildings can check their status and register through the MyWaste portal; the civic body has not yet set a fresh deadline for agencies to respond to its call.
