Algae are sometimes grown to make algae biofuels. Unlike biomass, many types of algae can be used and processed to become a biofuel. Biofuel is a fuel made from living things, or the waste of a living thing. The algae oils can be converted to biodiesel and the remaining material can be used to create bioethanol.
Both biodiesel and bioethanol are developing biofuels. Biodiesel is a renewable fuel made from seed oils. Bioethanol is an alcohol made from algae, corn, sugar cane or other sugar containing feedstock. It is usually blended with gasoline and used in internal combustion engines.
To convert algae to a biofuel, several steps need to be taken.
