Agricultural waste is common in Mauritius (sugar cane residue) and Southeast Asia (rice husks). Animal husbandry residues, such as poultry litter, are common in the UK.ugars present in this biomass are fermented to produce bioethanol, an alcohol fuel which can be used directly in a fuel cell to produce electricity or serve as an additive to gasoline.

Biomass is an industry term for getting energy by burning wood, and other organic matter. Burning biomass releases carbon emissions, around a quarter higher than burning coal, but has been classed as a renewable energy source in the EU and UN legal frameworks, because plants can be regrown. It has become popular among coal power stations, which switch from coal to biomass to comply with the law.
