Mumbai:In a significant step towards tackling the city’s massive plastic waste problem, The Ocean Cleanup has begun deploying its innovative Interceptor technology in two key Mumbai waterways. The initiative aims to stop an estimated 5 million kilograms of plastic from flowing into the Arabian Sea each year, offering a glimmer of hope for the city’s polluted creeks and coastal ecosystems.
The Netherlands-based non-profit organisation, known globally for its ambitious efforts to rid the oceans of plastic, has installed the first two Interceptors in Trombay Creek and Malad Creek. These solar-powered floating barriers are designed to capture trash in rivers and waterways before it reaches the sea. The deployments are part of the organisation’s “30 Cities Program,” which targets urban areas responsible for a large share of global riverine plastic pollution.
According to a year-long study by The Ocean Cleanup, Mumbai’s network of drains and creeks releases staggering amounts of plastic waste annually. This pollution affects over 220 kilometres of coastline, vast mangrove forests, and the livelihoods of nearly two million people dependent on marine resources. Plastic makes up around 80% of marine litter along India’s shores, harming marine life and entering the food chain.
Boyan Slat, founder and CEO of The Ocean Cleanup, highlighted the unique challenges in Mumbai. “The waterways here are highly tidal, so plastic doesn’t just flow one way — it can travel back upstream for kilometres during high tide,” he noted in earlier statements. The new Interceptors are specially adapted to handle these conditions, capturing waste moving in both directions.
Collaboration with Local Authorities
The project has received strong local support. The organisation signed a Memorandum of Understanding with the Maharashtra Pollution Control Board (MPCB) and secured necessary permits from the Brihanmumbai Municipal Corporation (BMC). On-ground operations and waste collection will be handled by Plastic Fischer, a social enterprise with a strong presence in India, in partnership with United Way Mumbai.
Initial estimates suggest the two pilot Interceptors could recover between 61 and 92 tonnes of plastic in the first phase. Over the next three years, the plan is to scale up operations to cover more of the city’s approximately 50 major pollution hotspots.
Environmentalists and residents have welcomed the move. “For years, we’ve seen our creeks turn into garbage dumps, especially during monsoons when waste flows freely into the sea,” said a local fisherman from the Malad area. “If this technology works, it could make a real difference not just for the ocean but for our daily lives too.”
A Global Effort with Local Impact
Mumbai is one of the key cities in The Ocean Cleanup’s global strategy, as part of efforts to prevent up to one-third of river-based plastic emissions worldwide by 2030. The Interceptors have already proven successful in other locations across Asia, Latin America, and the United States.
While the technology offers an engineering solution, experts emphasise that it must go hand-in-hand with better waste management, public awareness, and stricter enforcement on single-use plastics.
As the Interceptors begin their work silently in Mumbai’s creeks, they represent more than just machines — they symbolise a growing recognition that stopping plastic at the source is crucial if we want to save our oceans. For a city that battles flooding and pollution every monsoon, this could mark the beginning of a much-needed cleanup.
