How can we produce biofuels in agriculture?

Biofuels are fuels that are produced by humans using organic matter. Biofuels are considered renewable because of their production source. The most common biofuels are biodiesel, bioethanol (liquids), and biogas (gas). The biofuels are either the main product or a by-product of the farm. Canola, sunflower, and soybean are typical crops for biodiesel production. On the other hand, bioethanol is produced from sugarcane, sugarbeet, cassava, etc. It's also made from sugar-rich food waste and non-marketable production. Biogas, the third biofuel on the list, is produced from materials such as manure, plant material, food waste, and dead animals. Biogas is produced by anaerobic digestion of microorganisms, and the main component is methane. There is a public discussion about how green is biofuel production and the land use for this proposal.
