Qantas has confirmed that it is undertaking a feasibility study into the production of aviation fuel from waste, including food scaps, tree cuttings and packaging. The company expects to complete the feasibility study within a year after which it will be trialled in aircraft.

Air New Zealand has already trialled the use of a blend of jet fuel and jatropha oil in an engine of a Boeing 747-400. In February, British Airways contracted to build a £200 million ($305 million) plant in London by 2014 to turn up to 500,000 tonnes of waste a year into 73 million litres of jet fuel.
