Commercial airlines received permission to use plant-derived fuels this month from an international safety watchdog. This means airline fuel could be made from algae, wood chips or bio waste with Airbus and Boeing estimating that plant-derived formulas could make up to 30% of aviation fuels by 2030.
International safety adviser, ASTM International, approved the use of bio fuels in commercial aviation after years of testing by airlines. Bloomberg reports that carriers can now mix fuels derived from organic waste, so non-food products, with kerosene. This is an important development with pressure growing on the aviation industry to cut carbon emissions. However, an environmental strategist at Boeing told Bloomberg that it may be five years at least before the fuels are price competitive.
