Actually pyrolization is much cleaner than you would think, + you are returning some of the carbon into the earth, where it will remain 'sequestered' (actually as part of the structure or crumb of the top soil) indefinitely. So its carbon negative, usefull, elegant, and not as pays for itself, as oil from the process can be used to run the process once it gets started. Its going to be biochar and mushrooms baby.

Woow that is an expensive way to bury the CO2 problem

At 1:02 i understand she says that we can stuck CO2 in ground as Charcoal...

Great, but charcoal is just carbon. To make charcoal, it release the famous CO2...

Carbon doesn't

what process was used to produce the bio-char back then?

[dektronic07]

The biochar produced can be plowed into the soil; where it should improve soil structure; soil biology; nutrient retention, water retention; and reduce emissions of methane (CH4), nitrous oxides, and other GreenHouse Gasses (GHG) normally produced by microbes in the soil. These changes in the soil serve to greatly improve overall soil fertility levels while simultaneously sequestering large amounts of carbon- in effect helping to create a large, stable, geologic carbon reservoir in the soil.

bolafelpruda, Biochar would be produced mainly from agricultural wastes, not wood. This would be done via a process known as pyrolysis- which releases about half the carbon as CO2 and sequesters the other half as biochar, bio-oil, and syngas (note that I have heard other accounts that half is as biochar and the other half as bio-oil + syngas.) The half released as CO2 would otherwise at the very least have soon been released as CO2 and methane by decomposition. The biochar produced can be...

sorry, but are every one forgeting that is produce from burning wood?????????

that produce a lot of carbon!!!

will never be a valide process, produce more carbon, to say that land will prision on it!!!

what kind of university are you?

god luck for those neuronious lol

[Marmaleenie]

you are missing the difference between burning the organic waste vs. charring it (low-oxygen), which has minimal emissions that can be recaptured and used as fuel. The charcoal that is produced can be put into the soil to increase fertility and sequester (lock up) the carbon.

[dektronic07]

bolafelpuda, first of all, please learn to spell.

Second, you fail to understand that burning wood is actually usually a carbon-neutral activity. Because the carbon in wood is already a part of the carbon cycle, burning it is not releasing any new carbon into the atmosphere. In fact, were the wood allowed to decompose, large amounts of methane would be produced (a GHG 4 times more potent than CO2).

Biochar production is not the same as burning, and isn't usually done to wood, anyways.
