I knew someone would mention the machines and process but that *could* be
run on biofuel not dino. B-) Fertilizer as you say further down plenty
of **** about, regularly gets spread on the fields round here.

No biofuels operation anywhere is zero emission.

And probably never will be, if your fertilizer comes from cattle they
fart prodigious quantities of methane, another greenhouse gas. B-)

... this week's NS has what may well be the solution, algae. You can
take the CO2 effluent from a power plant and run it through bioreactors
that grow algae,

I agree algae or other micro organisms is probably a better method than
waiting for plants to grow, harvest, transport, extract etc.
