Currently, the major portion of biodiesel production in the UK comes from imported soya, palm and jatrophe oils, along with locally grown oilseed rape, with a smaller contribution from recycled waste vegetable oil and animal fats. Bioethanol is sourced primarily from imports. However, a number of companies have announced plans to increase production of biofuels, either by expansion of existing plants or through construction of new plants which will use UK grown crops such as sugar beet, wheat and oilseed rape as a feedstock. Such biofuel production plants are being stimulated by a mix of Road Fuel Duty reduction and the forthcoming Renewable Transport Fuel Obligation. The Government are also keen to support “second generation” biofuels which use more advanced technologies and have the potential to use straw, wood and biodegradable waste as feedstocks and is supporting a number of projects through the Technology Programme in this area. However, the majority of these processes are currently not proven at commercial scale. There is also significant development of biofuels internationally.
