A Canadian firm has expressed interest in setting up a waste-to-energy (WTE) plant on a public-private partnership (PPP) basis at Devguradia trenching ground.
The offer comes just as the municipal limits have been expanded by the addition of 29 nearby villages — a move likely to boost daily waste generation significantly.
The firm, Auto Thermic Gassification Solution Ltd, outlined its proposal in a presentation made before divisional commissioner Sanjay Dubey.
Trade commissioner, Canadian Embassy, Joachim Rocha, accompanied the firm’s representatives. Municipal commissioner Rakesh Singh and other IMC officials were present on the occasion.
The IMC wants to set up the WTE facility on a PPP basis and will provide ten acres of land and deliver garbage to the site. In return, it has asked the interested parties to submit bids stating whether they would operate on a zero sum or would pay/seek money from or to the IMC.
Auto Thermic representatives said a total of ten WTE plants would be built at the site so that they could be maintained on a revolving basis on days; Sunday for instance, when garbage generation was low.
The company claimed that more than 60% of waste could be converted to electricity through gasification — the technique it uses.
Gasification, claimed the Canadian firm, was also less polluting and required lesser fuel compared to pyrolysis, an alternative technique for generating waste from energy.
Divisional commissioner Sanjay Dubey confirmed the reports. “We asked them to come through the bidding process." Online tenders for the WTE were floated on Saturday and the Indore Municipal Corporation (IMC) has set December 24 as the last date for submitting bids.
"Gasification has a startup temperature of 650 degrees Celsius and only requires some auxiliary fuel at the initial stage. It also releases much less amounts of environmentally damaging CO2, CO and ash,” said Asad Warsi of Ecopro, the Corporation’s waste management consultant. Generating energy through pyrolysis, on the other hand, requires “forged energy” to be introduced to keep the plant running.
In response to a question, he said the addition of 29 villages would increase the daily waste generation which currently stands at 1,000 metric tonnes by around 200 metric tonnes.
The 29 villages have a total population of around 2 lakh and the waste generation has been calculated on the basis of 430 grams per person per day, he added.
