Harnessing Biogas from Food Waste

The video explores the potential of biogas as a renewable energy source, highlighting its production from food waste at the Bowen Pally market in Hyderabad, India. The process involves anaerobic digestion, which converts waste into methane and carbon dioxide, reducing landfill emissions. Biogas is used to power kitchens and produce fertilizer, benefiting local farmers. Despite its advantages, biogas faces cost challenges compared to fossil fuels, especially in North America. However, its adoption is growing globally, with projects in Europe, Africa, and Asia. Biogas helps reduce waste and emissions, offering a sustainable energy alternative.
