A UK-based aviation company has created jet fuel from human poop.

Firefly Green Fuels has been developing low-carbon fuel for approx 20 years. CEO James Hygate told the BBC that the company experimented with things like waste oil, waste food, and agricultural scraps, before turning to human waste.

Scientists converted human waste into fuel through a process called hydrothermal liquefaction, which uses heat and high pressure to turn the waste into carbon-rich biochar and crude oil, according to CNN.

Firefly Green Fuels worked with Cranfield University to analyze the carbon impact of the fuel's life cycle, finding that it has a 90% lower carbon footprint than standard fossil fuel-based jet fuel. Aviation regulators also conducted independent tests and found that the waste-based fuel was almost identical to standard jet fuel. Hygate said that the new fuel is chemically similar to kerosene but that it 'has no fossil carbon, it's a fossil-free fuel.'

The UK Department of Transport awarded the team a research grant of £2 million (approx $2.5 million). The team is also raising money to build a full-scale demonstrator factory.

The fuel has the potential to make the industry more sustainable and lower global carbon emissions. Hygate calculated that the UK's total human waste supply could meet around 5% of its total aviation fuel demand.
