Assessing the Feasibility of CBG Plants in Reducing Biodegradable Waste in Indian Cities

India's rapid urbanization and population growth, coupled with changing lifestyles, increased consumption of outside food, and proliferation of restaurants, hotels, and street food vendors, have led to a significant increase in biodegradable waste. Traditional practices of disposing of waste in streets, sewer trenches, open grounds, and landfills not only pose health risks but also contribute to environmental pollution, including leachate generation and contamination of soil and groundwater. Furthermore, the lack of segregation at source results in the mixing of biodegradable and non-biodegradable waste, making treatment and recycling challenging. This mixing also decreases the efficiency of recycling non-biodegradable waste. However, biodegradable waste can be converted into a valuable resource if managed properly and treated technically. This study explores the potential of Compressed Bio Gas (CBG) plants in reducing biodegradable waste in Indian cities, evaluating their technical, economic, and environmental viability. By harnessing the energy potential of biodegradable waste, CBG plants can provide a sustainable solution for waste management, mitigate environmental pollution, and generate renewable energy. A comprehensive review of existing literature and case studies reveals that CBG plants can significantly reduce biodegradable waste and provide a viable option for waste management and renewable energy production in India.
