When produced from waste cooking oil, biofuel offers significant carbon savings as a heating fuel when compared to kerosene and gasoil. All of the U.K’s 100 million tonnes of waste cooking oil which was previously sent to landfill can now be effectively recycled for liquid biofuel production. If produced from pure vegetable oil, the carbon footprint of biofuel is higher than that made from waste cooking oil but considerably lower than fossil fuels.

Liquid biofuel is more sustainable as a heating fuel than if used as a transport fuel. A modern boiler will operate with biofuel at efficiencies of about 90% whereas if used as transport fuel, the efficiency is only about 30%, this makes liquid biofuel used for heating three times more efficient and significantly more sustainable.
