The Greater Chennai Corporation (GCC) is moving forward with plans to expand its composting infrastructure as part of a broader strategy to strengthen solid waste management across the city. A 1,000-tonne windrow compost plant will be established on 20 acres of biomined land at the Perungudi dump yard under a public-private partnership model.
New Composting Plants in North Chennai
In north Chennai, two additional composting plants, each with a capacity of 50 tonnes per day, will be set up in Manali at a cost of 15 crore. Officials stated that these projects will enable scientific processing of wet waste and significantly reduce the burden on existing landfill sites.
Benefits of the Perungudi Facility
The Perungudi facility is expected to serve the southern parts of the city, where the volume of biodegradable waste has steadily increased in recent years. A senior GCC official explained, "The windrow composting method, which involves decomposing organic waste in long rows under controlled aeration, will significantly reduce the amount of wet waste reaching landfills. The compost generated can be used for horticulture, landscaping, and agricultural purposes, contributing to a circular waste management system."
Decentralised Waste Processing Strategy
The initiative at Manali is part of the corporation's broader strategy to decentralise waste processing and minimise dependence on landfill sites. Chennai generates over 6,000 tonnes of solid waste every day, with a substantial portion comprising biodegradable material. By expanding local composting capacity, the city aims to improve collection efficiency, lower transportation costs, and reduce environmental impact.
Modernisation and Sustainability
These projects also form part of efforts to modernise waste management infrastructure, promote sustainable disposal practices, and enhance resource recovery. Environmental experts have welcomed the move, noting that decentralised composting is critical for cities grappling with mounting waste. R Sundararajan, an environmental expert, said, "Large-scale composting facilities help divert organic waste from landfills, cut methane emissions, and extend the lifespan of dumping grounds."
