PILE UP: Garbage trucks bring about 1,800 tonnes of solid waste from various parts of the city to the Kodungaiyur dumping yard every day.

Chennai: About 30 companies have expressed interest in the solid waste management project at the Kodungaiyur dumping yard to manufacture compost, fuel pellets and electricity from garbage.

The civic body had sought the help of the Tamil Nadu Industrial Development Corporation Limited (TIDCO) to prepare a bid document, inviting contractors to implement integrated solid waste processing and disposal facilities.

The facilities include plants for manufacturing compost, generation of power from refuse-derived fuel and manufacturing bricks from stones and soil. Waste that cannot be processed would be stored in a landfill.

The bidding firms would have to submit their proposals by April 16. The proposals would be evaluated and a firm chosen by the end of April, Mayor M. Subramanian said.

Managing waste

Solid waste of 3,500 tonnes per day (tpd) is generated in Chennai and is dumped in Perungudi and Kodungaiyur. Residential waste forms about 70 per cent of the solid waste generated. If the arbitrary disposal of garbage continues, Chennai will not have any dumping space left in less than 10 years. The integrated waste processing facility would be used to curb dumping of waste and to generate revenue from the processed material.

The facility planned at Kodungaiyur will have the capacity to manage about 1,800 tonnes per day and would be operated by the private developer for a period of 18 years.

The project envisages reducing the garbage dumped in landfill to about 10 – 12 per cent of the garbage generated every day.

The technology to be used would have to be compliant with the Municipal Solid Waste Management and Handling Rules of 2000.
