Mumbai civic body to set up small biomethanisation plants across city

The Brihanmumbai Municipal Corporation (BMC) is constructing nine mini waste-to-energy or biomethanisation plants with a daily capacity of two metric tonnes (MT) of organic waste. These will be located throughout Mumbai with the goal of reducing the amount of wet waste sent to the Deonar and Kanjurmarg dumping grounds.

Mumbai currently sends approximately 6,500 MT of waste to the two dumping grounds and is planning decentralised waste management and segregation at each ward.

There are three operational mini waste-to-energy plants: one each in Pali Hill and Haji Ali that can handle two MT of organic waste per day, and one in Malad that can handle 30 MT of organic waste per day, reports The Indian Express.

Wards have been directed to locate suitable plots within their jurisdiction for the installation of the nine biomethanisation plants.” The electricity generated by each plant will be used in the nearest BMC building. After meeting basic consumption demand, BMC estimates net electricity production of 30 to 50 units per day. The remainder will be paid to the electricity provider for metering. A total of 300kg of manure will be produced per day and used in municipal gardens and plantations throughout the city.

BMC recently issued tenders for the construction of biomethanisation plants, which include contracts for operation and maintenance for a five-year period after construction is completed.
