Abstract

                                Food losses and waste are the third most prominent source of greenhouse gas emissions. Agriculture waste being biodegradable can be composted to generate biofuel instead of dumping it into landfills. Understanding this, the Bowenpally market of Telangana, in 2020, has set up a sustainable biogas plant of 10 tons capacity. In the present study, details regarding waste management were collected and presented in a case study form - Problems, course of events, relevant factors, outcome, and analysis as suggested by Spicer (1952). Ten tons of approximate daily waste of the market can generate up to 6,290 kg of CO2 per annum. ‘Anaerobic gas lift reactor’ produces biofuel supplied to market kitchens and power the street lights and stalls. Within due time Bowenpally market digested 1,400 tons of vegetable waste that produced 32,000 units of electricity and 7,000 Kilo Litres of bio manure. Such recycling and recovery management practices, which are low cost, are the need of the hour. This study tries to bring the initiative of the local mandi into the limelight that has vast scope to replicate at different markets, hostels, canteens, etc.
