Food crops rich in sugar, starch or oil make great biofuel, but this practice has become controversial since arable land that could be used for food production is used for fuel production instead. When talking about biofuels, it is common to divide them into generations, to denote the developments within the field of large-scale commercial biofuel production.īiofuels made from food crops are considered first-generation biofuels. Examples of commonly used oils and fats for the production of biodiesel are corn oil, canola oil and soybean oil. sugar cane, corn or sweet sorghum, but several other biomass sources are utilized on a commercial scale as well today, including wood and grasses.īiodiesel is produced from oils or other fats through a process called trans-esterification. ![]() Typically, biomass very rich in carbohydrates is selected for bioethanol production, e.g. The two most common types of processed biofuel today are bio-ethanol and bio-diesel.īioethanol is ethanol made by allowing the biomass to ferment. using wood logs to fuel a fire for cooking and space heating. ![]() Some types of biofuel can be used without much processing, e.g. While the production of fossil fuels such as crude oil is formed through the heating and compression of biomass over thousands of years, renewable biofuel production is much more rapid. ![]() Unlike fossil fuels, biofuels from renewable sources can be produced from biomass very quickly.
