CM Vijay Inspects Chennai's Bio-CNG Plant, Orders Waste Segregation

Tamil Nadu Chief Minister C. Joseph Vijay conducted a surprise inspection of the Bio-CNG plant at Chetpet in Chennai on Monday, reviewing the state's waste management efforts and directing officials to strengthen scientific processing of municipal waste. During the visit, the Chief Minister stressed the importance of improving waste segregation at the source and expanding similar waste-to-energy initiatives across urban areas in Tamil Nadu to promote sustainable waste management.

The Bio-CNG plant at Chetpet processes around 100 metric tonnes of food and vegetable waste every day under a public-private partnership (PPP) model. The facility is regarded as India's first Bio-CNG plant of its kind in Chennai and converts biodegradable waste into bio-compressed natural gas (Bio-CNG), helping reduce landfill waste while generating clean energy from organic refuse.

During the inspection, Vijay instructed officials to ensure effective segregation of waste at the household level so that biodegradable and non-biodegradable waste can be processed separately. He said biodegradable waste should be scientifically converted into Bio-CNG, while non-biodegradable waste should be utilised for road construction and as an alternative fuel in the cement industry wherever feasible. He also emphasised the need to minimise waste sent to landfills through improved recycling and resource recovery.

The Chief Minister further directed officials to formulate a time-bound plan to implement scientific waste management practices across the state. He called for similar Bio-CNG and waste-processing facilities to be established in other urban centres, highlighting the role of modern waste management infrastructure in improving sanitation, protecting the environment and supporting the state's sustainable development goals.

According to an official release, the Greater Chennai Corporation collects approximately 6,150 metric tonnes of solid waste every day. Of this, around 3,200 metric tonnes consist of biodegradable waste, while the remaining 2,950 metric tonnes comprise non-biodegradable waste and roadside soil particles. The figures underline the scale of the city's waste management challenge and the need for efficient segregation and scientific disposal systems.

The inspection reflects the Tamil Nadu government's continued focus on strengthening urban waste management and promoting environmentally sustainable practices. By encouraging source segregation, expanding Bio-CNG production and identifying productive uses for non-biodegradable waste, the state aims to reduce environmental pollution, improve resource utilisation and develop a more efficient solid waste management system across Tamil Nadu.
