Biofuel or biogas is a renewable and eco-friendly energy source produced through the anaerobic digestion of organic materials, such as animal manure, agricultural residues, and food waste. During this natural process, microorganisms break down the organic matter, releasing a mixture of gases primarily composed of methane and carbon dioxide. This methane-rich gas can be harnessed and utilized as a clean and sustainable alternative to traditional fossil fuels, providing a cost-effective and environmentally conscious solution for energy needs. Biogas not only helps in waste management by converting organic waste into valuable energy but also contributes to reducing greenhouse gas emissions, making it an essential part of the transition towards a greener and more sustainable future.
