Gloucestershire firm making jet fuel entirely from human poo

A new aviation company has developed a type of jet fuel made entirely from human sewage.

Chemists at a lab in Gloucestershire have turned the waste into kerosene.

Dr Sergio Lima, research director at Firefly Green Fuels, said: "What we are producing here is a fuel which is net zero."

Independent tests have found the fuel is nearly identical to standard fossil jet fuel.
