The Greater Chennai Corporation (GCC) has achieved a major milestone in its mission for a cleaner city by processing 15 lakh tonnes of legacy waste at the Kodungaiyur dumpyard in just eight months. Carried out in four phases, the initiative also included the safe disposal of more than 1.4 lakh tonnes of Refuse-Derived Fuel (#RDF: fuel made from non-recyclable waste used in industries like cement kilns). This week, the concessionaire will hand over two acres of reclaimed land to GCC to launch a plantation drive, marking a key step forward in Chennai’s waste remediation programme.
Permanent Electrical Connections Boost Waste Processing
One of the most critical enablers of this success was the installation of permanent electrical connections at the biomining site.
- The shift from diesel generators to direct electrical connections has tremendously increased daily waste processing volumes.
- The new infrastructure also ensures uninterrupted power supply for the biomining project and future developments in Kodungaiyur.
GCC Commissioner J. Kumaragurubaran stated, “Of the 67 lakh tonnes, we have processed 15 lakh tonnes so far. By September-end, we expect to reach 20 lakh tonnes. All packages at the site are now fully connected to the electrical grid.”
Anna University Monitoring and Certification
Anna University serves as the Project Monitoring Committee (PMC), overseeing the operations carried out by three contractors working on the biomining project. The university is responsible for:
- Supervising and monitoring all biomining activities.
- Certifying the quality of legacy waste disposal.
- Approving processes related to landfill clearance and remediation.
This oversight ensures the project maintains high environmental and operational standards.
Eco-Friendly Alternatives to Waste-to-Energy Plant
Even as progress continues, residents in north Chennai are pushing for sustainable waste management solutions. Resident welfare associations plan to propose alternatives to the controversial waste-to-energy (WTE) plant, including:
- Establishing 1,000 decentralised compost units across Chennai.
- Setting up recycling centres to minimise landfill load.
- Developing Resource Recovery Centres (RRCs) to segregate and repurpose waste.
- Implementing zero-waste management practices citywide.
These measures could help Chennai move closer to a circular economy model, reducing reliance on traditional landfills and incineration.
The Road Ahead
With 15 lakh tonnes already cleared and a target of 20 lakh tonnes by September-end, the Kodungaiyur biomining project is poised to transform the city’s waste management landscape. The reclaimed land, future plantation drives, and growing focus on decentralised solutions could signal the beginning of a greener, cleaner Chennai.
