UK firm develops jet fuel made from human poo | The starting material is generated in excess and available in plenty. It is a win-win for everyone that the waste is repurposed.::undefined

Will it still pollute the atmosphere?

[–] ForgotAboutDre 8 points 10 months ago (1 children)

Yes. But the waste is likely to still produce methane that has a bigger climate warming effect that the equivalent co2 of burned but for a shorter period. The general consensus suggests it's better to burn methane than release it into the environment.

The better solution is to fly less, or wait till flying truly green. The big issue is the incredible amount of subsidy we allow for airlines. Tax or fuel for aircraft is very low. If we cut these subsidies and starting taxing aircraft fuel at similar rates to cars electric/hydrogen aircraft would come about much sooner.

Also, if its in human poo it's already in the carbon cycle and so really less of an issue. The problem is bringing up carbon that's been removed from the cycle (subterranean oil or gas pockets) and putting that back into circulation. Granted it would be better to pull carbon out of the atmosphere (somehow), but at least using poo wouldn't be adding NEW carbon. That's my understanding anyway.
