In the race for sustainable fuel alternatives to replace traditional jet fuel, a UK startup named Firefly Green Fuels has found an innovative way to use human waste.
Specifically, to convert human waste into usable fuel, Firefly employs a method known as hydrothermal liquefaction, which is particularly effective for wet waste.
By combining high pressure and heat, scientists have successfully transformed wastewater into carbon-rich biochar, a powder that can be used as fertilizer and crude oil.
According to Firefly Green Fuels and experts at Cranfield University, this renewable fuel emits 90% less carbon compared to traditional jet fuel.
The creation of carbon-neutral and non-fossil fuel is considered a promising invention. However, according to the BBC, the entire wastewater supply in the UK would only meet 5% of the country’s total aviation fuel demand.
Additionally, funding for wastewater treatment facilities poses a challenge due to capital issues. According to CEO James Hygate, Firefly Green Fuels has so far received a research grant of $2.5 million from the UK government and $6.3 million from European airline Wizz Air.
