Fourteenth International Conference on Climate Change: Impacts & Responses

Abstract

To highlight best organic waste management strategies to achieve carbon footprint benefits, the present study was conducted on food, green, and kitchen waste composting using windrow composting. The membrane covers windrows with basal layer bulking agent (grass clippings) generating a bottom-up ventilation system, resulting in micro-positive pressure, decreasing the anaerobic zone in compost pile and GHGs emissions and making the piles aerobic, and odorless (organoleptic) and result in less carbon dioxide leakage (avoidance) and sequestration. Micro-positive pressure hastens decomposition due to prolonged thermophilic and reduces GHGs emission by 40%.The integrated mechanical and manual strategy, namely the two stage composting system (TCS),the organic compost with standardise parameters is obtained in 110 days, to prevent the landfills interruption of the carbon cycle ,saving 38,520 kg CO2 (88%)in single cycle .The project reproducibility and scalability tested to two institutes of repute. The project results in carbon mitigation which would eventually become tradable carbon credits; a total of 346.7 million tons of carbon dioxide emissions, generating 346 carbon credits till inception and around 8.71 lakhs are gained through the study. Besides this, 564 quintals organic compost is generated worth 16 lakhs, hence in total the study amounted nearly 25 lakhs rupee till inception in 300kg waste. The problem solved due to the bioconversion of solid waste are its management are: Unscientific land filling; Maintaining soil fertility; Avoiding the breeding grounds for mosquitoes; Saving precious Farm yard Manure(FYM), which is used in agriculture and in Biogas Plants for sustainable development.
