Pune: Pune city generates tonnes of solid waste, which is very difficult to dispose of. In such a scenario, it would be environmentally sustainable to generate biogas from waste, noted Gajanan Patil, Director of Urja-Bio system. Patil has successfully established biogas systems in Maharashtra in last 10 years and has also helped London Municipal Corporation in solid waste management.
Every day, Mumbai generates 9,000 tonnes of solid waste whereas Pune generates 1,800 tonnes. From October 1, 2017, Brihanmumbai Municipal Corporation (BMC) has made it mandatory that it will dispose of only 100 kg of solid waste from societies, malls and hotels.
This has led to solid waste management initiatives at various levels. In such a situation, making biogas out of waste seems to be a better and viable option and a plant can be set-up starting from two kg of waste.
Patil mentioned that the biogas plant can be constructed underground and can also help in generation of electricity.
He further added that this electricity can be used in pumps and lifts. An added benefit is that such plants can also give compensation of five per cent of society tax. For more details, anyone interested can contact on www.urjabiosystems.com.
Effective establishment of biogas plants
† Second heart township at Wanawadi has 600 flats and generates 600 kg of solid waste every day. There 50 cubic meter plant for generation of biogas is producing 10 kilowatt electricity.
† Biogas plant and home are a kilometer away from each other near Baramati. Still, the biogas generated there provides gas to around 14 households throughout the day.
† Organisations like MEDA and MNRE can help societies to extend financial help for biogas plants up to 25 cubic meter and three kilowatt.
† A two cubic meter plant needs Rs 32,000 and it can subsidy around Rs 9,000. Similarly, a plant of 25 cubic meter can get a total subsidy of Rs two lakh and 40,000 from Central and state government
.† At the moment, State government does not provide a subsidy for plants ranging from four cubic meter to 20 cubic meter. If some policy level changes are made, any farmer or society can have its own biogas plant.
