Field-level officials told to do a street-wise mapping of Central Zone.

The Coimbatore Corporation is in the process of fine-tuning its waste management strategy. As a first step in this direction, the Corporation officials led by Commissioner G. Latha listened to conservancy workers in the Central Zone. This was part of the efforts to streamline waste collection.

Consequent upon the meeting, the Commissioner asked field-level officials to do a street-wise mapping of the Zone, the bins available there and the waste collected in every bin. Ms. Latha said that she had asked the officials to do so after she found that at most places the bins placed were totally inappropriate for the waste generated.

The Corporation has around 500 bins in the Central Zone and they vary from 0.3 tonnes to five tonnes.

Once the study was complete, the staff would present a report to her, based on which officials in-charge of solid waste management and she would decide on placing the right bins at the right place with the right spacing.

Ms. Latha said that the Corporation had made some progress in this regard and would implement the scheme in the Central Zone in a few days from then.

Debris management

As part of the efforts to tweak the waste management system, the Commissioner said that she had asked the officials to identify reserve sites in each ward and zone to be used to dump debris. The move was a fall-out of the meeting with the conservancy workers and sanitary supervisors.

“One of the biggest problems they faced in collecting garbage was debris. Once they collected the debris from roads, they were unable to collect garbage. This affected the regular waste collection.”

Small scale contractors and builders could use the site at the wards if the quantity was small and those with more debris could use the big open spaces identified at the zonal level, the Commissioner said.

As a follow up to the decision, Ms. Latha said that she had called for a meeting with the contractors and builders to convey the decision and seek their cooperation.

Animal waste

Another decision the Corporation has taken after the meeting is regarding animal waste collection. Those selling meat and fish would be asked to handover the waste to conservancy workers/sanitary supervisors or others who would be on rounds to collect such waste. Upon handing over the waste, the workers/supervisors would issue acknowledgement receipts. The traders should retain the receipts and produce the same on demand. If they failed to do so, the Corporation would be forced to construe that they had dumped the waste and not handed over the same to its men. The traders would also face penal action, the Commissioner said and added that such a move was to ensure compliance.

Source segregation of garbage soon

Staff Reporter 

Even as announcements pertaining to source segregation and solid waste management are being made in each budget speech, Chennai is struggling to cope with garbage problems.

In his budget speech, Finance Minister O.Paneerselvam admitted that solid waste management in urban areas was a major challenge. “This government will continue to promote source segregation and recycling to limit the disposal of solid waste through land fills,” he said.

In last year’s budget speech, the finance minister had said: “All urban local bodies will practice source segregation of solid waste into degradable and non-degradable components in a phased manner. The government will soon announce an Integrated Solid Waste Management Policy.”

However, solid waste management neither had contours of a policy nor was integrated. The practice of source segregation in Chennai is yet to become popular among residents. A few of the zones trying to promote source segregation have been not successful yet. The civic body has identified some streets such as Mottai Garden Street in ward 48 for promoting source segregation. But the process will be complete only after infrastructure for compost yard is ready. Residents in divisions such as 34 and 35 also reported distribution of pamphlets by Corporation officials to promote source segregation this week.

Over 4,900 tonne of municipal solid waste reaches Kodungaiyur and Perungudi dump yards, where unscientific dumping of waste has been causing fire, smoke and pollution for years.  

“Waste to energy projects will be established wherever possible,” the Finance Minister said in the budget speech 2013-2014.

Announcements on waste to energy projects in Kuthambakkam and Minjur are likely to be made next month if an expert panel identifies clean technology among the proposals made by a few companies to Chennai Corporation.

The Corporation has shortlisted 10 proposals for the plants to process 4500 tonnes of municipal solid waste generated in the city. Most of the technologies for converting waste to energy are not environment friendly and the experts are likely to reject most of the proposals next week. Residents of the localities have already voiced concerns about the proposed solid waste management plants.

Experts to screen proposals for waste management plants

A panel of experts from agencies including Central Pollution Control Board and National Environmental Engineering Research Institute will scrutinise proposals for new solid waste management plants in the city.

The Chennai Corporation has shortlisted 10 proposals for the plants that are to come up on the outskirts. All the shortlisted companies will make a detailed presentation of the proposals and experts will identify technology that is clean.

They will reject technologies likely to pollute neighbourhoods such as Kuthambakkam and Minjur, after the city’s waste management plants are commissioned in such areas. Residents of the localities have already voiced concerns about the proposed solid waste management plants.

Of the 10 bids received by the Corporation from private companies for the setting up of such plants to process municipal solid waste, six have proposed that such a facility be set up in Kuthambakkam.

“The experts will study the impact of technology such as incineration for the solid waste management plants. We will not accept any proposal that has not been proved environment friendly,” said an official of Chennai Corporation.

 Incineration technology for management of municipal solid waste involves conversion of the waste into ash and heat. The ash is mostly formed by the inorganic constituents of the waste, and may take the form of particulates. The emissions must be cleaned of gaseous and particulate pollutants before release into the atmosphere.

The development of a system to reduce emissions will be the priority of the expert panel. New ideas may not be accepted by the panel. After the panel finalises the technical aspects of the bid, the financial details will be finalised next week.

Kuthambakkam, which has a 99-acre plot of land, is likely to be the most suitable place for commissioning the facility, say Chennai Corporation officials. Most of the city’s waste is likely to be processed in the proposed Kuthambakkam plant. Initially, more than 2,500 tonnes of municipal solid waste generated in the southern parts of the city will be processed in Kuthambakkam.
