Biofuel

A fuel produced from plant or animal matter. There are currently two types of biofuel: biodiesel, manufactured from oil-rich plants like rapeseed, oil palm and soybeans; and bioethanol, based on fermenting sugar derived from plants like sugarcane, corn, sugar beet and wheat. Research is currently focused on developing advanced biofuels derived from the inedible parts of plants. This would reduce competition between food crops and the transportation sector.
