MUMBAI: The Brihanmumbai Municipal Corporation (BMC) is planning to set up biogas plants in all the 24 wards in the city to recycle kitchen waste that can be used as fuel for cooking or power generation purposes.
According to civic officials, every ward office will have a 25kg plant on its premises that can recycle fast-decomposing materials such as raw or cooked food waste from hotels and canteens, vegetable waste and waste from fish markets and slaughter houses that can be used to produce biogas. The plant will be set up at an approximate cost of Rs3-3.5 lakh in a 100 square metre area in every ward.
Biogas is a mixture of different gases with methane and carbon dioxide having a major portion in the mixture along with traces of gases such as hydrogen sulphide and hydrogen. The biogas generated from a domestic plant can be used for cooking, heating and generating electricity at households and institutions.
It is an important step in waste management in the city, which is currently struggling with its inefficient waste practices. BMC’s ambitious waste-to-energy project has also faced constant bureaucratic delays since 2013. At present, a feasibility study has been undertaken on the project by Tata Consultancy Services (TCS).
The civic body has already initiated tenders to set up the biogas plants and will begin the process in another two to three months, officials said. According to data from the solid waste management of the BMC, 52-65 per cent of the waste generated in the city is organic.
The city generates 9,000 metric tonnes of waste everyday which is dumped at Deonar, Mulund and Kanjurmarg. Dumping untreated waste in such huge quantities has led to massive fires in the Deonar dumping ground recently. Vijay Balamwar, deputy municipal commissioner, SWM said, “The gas produced will be used for cooking and power generation in the canteens itself. The process will be initiated soon.” In 2015, the solid waste management department had set up a model plant in Vile Parle to tackle waste management at the ward-level itself.
