British Airways (BA) has said it will build a new biojet fuel plant despite having not yet received approval from Ministry of Defence body DStan.

The plant will convert 500,000t of waste a year into 16 million gallons of green jet fuel that will reduce carbon emissions by up to 95% compared with fossil-fuel derived jet kerosene, according to the Guardian.

The volume of fuel produced at the plant would be over twice the amount required by BA flights at nearby London City Airport, the carrier claims.

BA plans to purchase the all the fuel produced by the plant, which will be in partnership with the Solena Group.

The airline expects the new fuel to be certified by the time the plant is built in 2014 and in case it does not receive certification, still plans to use it as the fuel was cleared by US safety authorities in 2009.
