One of the country's largest landfill sites, being readied at Gyaspur-Pirana on the outskirts of the city, will soon see a captive power plant in the coming months. The Ahmedabad Municipal Corporation (AMC) plans to burn "organic' waste collected from various domestic and commercial sources to run a generator running on steam. A formal contract has been assigned to a company called Solid Waste To Electricity Company (SELCO) International Limited for the Rs 40-crore plant coming up over an area of three hectare. The power plant will produce close to 4.5 lakh units of electricity in a month. A report pertaining to the sale of power has to be signed by SELCO with a local buyer and submitted to the Gujarat Electricity Regulatory Authority. However, the procedures for identifying a buyer are bit overdue and the deadline is the end of next month. Proper segregation of waste from organic waste would be done at the landfill site. Non-bio-degradable wastes like plastics, batteries, paints, leather products and various other electronic disposals that produce toxins like dioxins and furans on burning would be removed. Only the organic component of the garbage would be used for power generation. AMC dumps close to 2,500 tonnes of garbage in a day at Pirana. Out of this, AMC has pledged 500 to 800 tonnes of garbage to SELCO for burning purpose. However, waste first has to be made to go through an electromagnetic and sand separators and then a separate section in the plant would pulverise the waste into pellets. These pellets are then used to fire a boiler, the steam generated through this is then directed to run a turbine. "We have already given the contract to SELCO, but they have to find a local buyer within a month for their captive power. We feel that apart from strict regulations in place, we have to monitor the operators' activities to ensure that only organic waste gets burnt to produce steam and electricity,' says municipal commissioner IP Gautam.
