Mumbai's first C&D recycling plant turns 600 tonnes of debris a day into resources
The Brihanmumbai Municipal Corporation (BMC) paired its citizen-facing Debris-on-Call intake system with Mumbai's first city-scale C&D recycling hub at Kokanipada, Dahisar, operated by listed municipal services company Antony Waste. Commissioned in 2024 around CFlo's Reurban D5100 modular wet processing system, the plant processes around 600 tonnes of debris per day into graded recycled aggregates and two sand fractions.
Mumbai's construction boom left rubble and mixed debris piling up on open plots and roadside corners, adding to dust and choking scarce urban space. Urban debris arrives highly variable and often contaminated: concrete, brick, stone and soil with incidental plastics, mud, adhered mortar and variable moisture. Without robust scrubbing energy and controlled hydraulics, valuable fines either remain locked in aggregates or wash away as sludge. Tight plots, strict water control and variable feed set demanding constraints for any processing plant.
BMC built the intake side: Debris-on-Call via toll-free numbers and the MyBMC app, with geo-tagged requests and free collection of small quantities (up to 500 kg) to discourage illegal dumping. At Dahisar, CFlo's Reurban D5100 provides the process backbone, selected for its compact footprint, fast deployment and ability to maintain product consistency despite mixed urban feed.
The line follows a liberation-then-grading approach: primary reception and scalping remove oversize and obvious contaminants; intensive scrubbing breaks cementitious coatings and clay bonds; wet sizing and density separation recover clean aggregates of two sizes and two sand fractions (concrete and plaster); and a water-management loop thickens and recycles process water. High-energy scrubbing coupled with calibrated laminar separations maintains cut-point stability as feed changes, and because material arrives with source data, the operator tunes scrub intensity and classification set-points in near-real time.
Thousands of tonnes each month are diverted from landfill into inputs for city projects, while structured collection and rapid processing reduce open piles and resuspended dust. Recycled aggregates feed sub-base and blocks; sand-like fines go into pavers, kerbs and other urban elements, normalising recycled materials in day-to-day public works.
With a processing capacity of 600 tonnes per day, this state-of-the-art plant is reshaping the way Mumbai handles construction and demolition waste. What was once a growing burden on our landfills, is now being transformed into high-quality recycled sand and aggregates. CFlo's eco-friendly technology, with low power consumption and up to 95% water recycling, exemplifies the kind of sustainable innovation our cities urgently need.
