With a move to generate power supply in the city from green waste, the Chandigarh municipal corporation (MC) is all set to make two biomethanation plants of 5 metric tonnes each in Sectors 16 and 26, here.
The final proposal will come up in the house meeting scheduled in the last week of September.
Three councillors, including, city mayor Subhash Chawla and other officers visited Bhabha Atomic Research Centre (BARC), Mumbai, to study the technology used by them.
Congress councilor Pardeep Chhabra, who was part of the team, said, “Initially we will start with two plants. Later, it will be extended to other parts of the city as well. We are planning to use the energy (methane gas) produced at the plant to operate a generator. The generator in turn will supply power, which can be used for at least running the street lights.”
MC joint commissioner Rajeev Gupta said the plants will be set up for reducing the quantity of biowaste being transported to the garbage processing plant in Dadu Majra and instead use the waste to generate energy. With this, the corporation will achieve the twin objective of saving the cost of transporting biowaste to the compost plant, and reduce volume of waste being lifted from the market, he added.
Kitchen waste from some hotels and vegetable and green waste from various parts of the city will be shifted to the plant for producing the gas.
City mayor Subhash Chawla said, “At Mumbai, we saw that biogas generated in any biomethanation plant is a mixture of methane and carbon dioxide. The biogas generated contains more percentage of methane than the conventional process. Since the percentage of methane is higher, the flame will be better, and calorific value higher, in case of biogas generated in the plant.”
