Greater Chennai Corporation to raise awareness on segregating waste at home

Representative image
CHENNAI: The official theme for World Environment Day which falls on June 5 is connecting people with nature. But priorities for Greater Chennai Corporation lies in the basics -- separating your waste at home.

Officials are attempting creative posters and are trying to gather people to take mass pledges to launch source segregation as an everyday practice, which is an extension of the centre's Swachh Bharat Mission. The Ministry of Urban Development has been exerting pressure on the city corporation to show results and set a target.

So far, 3% of the 5,000 tonnes of waste generated every day is being segregated and does not go to the landfills in Kodungaiyur and Perungudi. "The Ministry of Urban Development has been asking us when we are going to achieve 100% segregation but it is hard to set a target now," said a source in the solid waste management department working to promote the union government's mission adding, "We can't achieve 100% until we have composting pits in all wards and we are in the process of identifying vacant lands and awaiting funds to carry them out."

Though civic officials have been conducting door-to-door awareness and demos on separating wet waste from dry waste and recycling methods, officials believe a special launch on a global day of observation could raise awareness. "The Ministry of Urban Development has sent us a model for campaigning and the entire department is working on that," said the official. Presently, gated communities and apartments primarily in central Chennai, south Chennai and Manali in north Chennai are leading the way in source segregation in the city.

Corporation asks apartments to manage their wet waste

Coimbatore Corporation has asked apartments to manage their wet waste and hand over to it only dry and recyclable waste.

In a release issued on Wednesday, the civic body said apartments could either go in for biogas plants to process the wet waste or turn it in to manure. They should either handover only dry and recylable waste to the Corporation, or sell these to recyclers.

As for households, the Corporation said it would collect the dry waste at their door-step but it should be segregated from the wet waste.

The directive on the wet waste was part of the Corporation's efforts to comply with the Central Government's directive to promote segregated waste collection from World Environment Day on June 5. The release also said that commercial establishments should also hand over waste only after segregation. The civic body issued the release after the Corporation Commissioner K. Vijayakarthikeyan held a meeting with senior officials.

“It could clear the entire solid waste at Ariyamangalam within five years”

The Tiruchi City Corporation plans to set up a Refuse Derived Fuel (RDF) plant on a Public and Private Participation (PPP) mode to convert waste to energy from the accumulated waste at its Ariyamangalam garbage dump.

Under the proposal, which is under the consideration of the Directorate of Municipal Administration, a RDF plant will be set up at an estimate of Rs. 25 crore to produce fuel from the solid waste dumped at Ariyamangalam. The plant is expected to handle about 600 tonnes a day to produce energy. Excavation, segregation and waste stabilisation were part of the process of producing fuel from waste.

According to a rough estimate, Tiruchi generates 450 tonne of waste daily from different parts of the city. Though there are four micro compost yards in the city, most of the solid waste is still being dumped in Ariyamangalam dump yard. It is said have stored about 11 lakh cubic meter of waste over the years.

Corporation authorities say that the earlier proposals such as bio-mapping and bio-mining were found to be expensive and time consuming. However, the Refuse Derived Fuel method was found to be functioning successfully at Maraimalai Adigal Nagar in Chennai and Pune in Maharashtra.

“We are badly in need of a viable method to the long pending problem of disposing the accumulated garbage at the dump. If we go ahead with the RDF proposal, I think, the entire solid waste at Ariyamangalam will be processed and cleared within five years,” said N. Ravichandran, Corporation Commissioner. Tiruchi.

It had been decided to implement the project on PPP mode. The Corporation would provide garbage and land at the dump yard on lease basis. The private agency would install machineries and take care of manpower requirement, he added.

Mr. Ravichandran said a team of officials had visited Maraimalai Adigal Nagar to study the functioning of the RDF plant. One more team would be sent shortly for the next level exposure.
