The Bioenergy business unit is spearheaded by the company Abengoa Bioenergy, which produces and develops biofuels for transportation, bioethanol and biodiesel among others, that employ biomass (cereal, sugarcane, cellulosic biomass, and oleaginous seeds) as raw material. Biofuels are used for ETBE production (a gasoline additive), or for direct blending with gasoline or diesel. Being renewable energy sources, biofuels help to lower CO2 emissions and enhance the security and diversification of the energy supply, while reducing dependency on fossil fuels in the transportation sector, and helping to reach compliance with the Kyoto Protocol.
