Biodiesel is a clean and renewable fuel made from natural sources like vegetable oils, animal fats, and used cooking oil. It is produced through a simple process that turns these oils into fuel that works in diesel engines. Using biodiesel helps reduce pollution, cut greenhouse gas emissions, and decrease the use of traditional fossil fuels. It also turns waste oils into a useful resource, helping to manage waste and protect the environment. In India, the government is encouraging the use of biodiesel by blending it with regular diesel, aiming for 5% blending by 2030, as part of efforts to promote sustainable energy and support rural development.
