biofuel
Corn-derived gasoline alternative
Biofuel is fuel derived from organic matter rather than fossil sources—typically plant materials like corn, sugarcane, or soybeans, but also algae, animal waste, or used cooking oil.
Ethanol and biodiesel are the most common types.
Biofuels are promoted as renewable alternatives to petroleum, though debates persist about their environmental benefits when accounting for land use and production costs.
