Biofuel is a renewable fuel that is made from organic matter, such as animal dung, crops, and other residue. It is a sustainable alternative to diesel, petrol, and other non-renewable fuels. There are several synonyms for biofuel, including biodiesel, biogas, biomethanol, and bioethanol. Biodiesel is made from vegetable oils, while biogas is generated from organic waste such as food scraps. Biomethanol and bioethanol are both produced from biomass sources such as cellulose or sugar. These synonyms for biofuel are becoming more popular and widely used as the world looks for ways to reduce its reliance on fossil fuels. They offer a more sustainable, cleaner, and more efficient alternative to traditional fuels.
