In India, Bowenpally’s waste-to-energy plant is generating dozens of kg of biofuel as well as jobs. The waste generated in Bowenpally vegetable market and nearby yards are collected from across the city. The vegetables are chopped into smaller pieces and run over the conveyor belt to the shredder. The waste then undergoes a shredding process where all the vegetables are crushed into smaller and uniform sizes and sent to a grinder. This grinder further crushes the content into pulp, which is also called slurry and passes them to the anaerobic digesters.
According to Bowenpally market officials, on average, 10 tons of waste is generated per day. This waste has the potential to generate approximately 6,290 kg of CO2 per annum which could be more damaging to the environment. To address this issue, Bowenpally vegetable market officials decided to turn this waste into energy.
The gas generated is collected and stored in balloons until further use. Bio Manure is obtained, apart from the gas, as a by-product. In a separate tank, biogas is collected and via a pipeline system sent for cooking. The biofuel is then supplied into a 100% biogas generator which is used to power the cold storage rooms, water pumps, shop, street lights, etc.
Around 30 kg of bio-fuel generated per day is supplied to the kitchen facilities near the unit. 400- 500 units of electrical power is being utilized by the administrative building, market water supply network, around 100 streetlights, and 170 stalls of the market.
Srinivas, the Secretary of Bowenpally’s vegetable market, highlighted that every ounce of vegetable and fruit waste collected from this market is used to generate around 500 units of electricity and 30 kg of biofuel. The electricity generated provides electricity to streetlights, 170 stalls, an administration building, and the water supply network. Meanwhile, the biofuel produced is pumped to the market’s commercial kitchen. The Biogas plant is now called the “path to a sustainable future”. The canteen in the market is being run by the electricity generated through the plant established. The market yard requires 650-700 units of power and about 7-8 tons of vegetable waste generated to produce 400 units of electricity on average. As a result, the marketplace is also kept clean and pollution free. Various international delegates have also visited the plant and appreciated our efforts.”
Bowenpally’s waste-to-energy plant generates employment for women by providing opportunities for them to work in various roles such as sorting and segregating waste, operating machinery, and managing administrative tasks. This plant offers women workers a steady income along with an opportunity for skill development.
