The Case for Burying Charcoal
Research shows that pyrolysis is the most climate-friendly way to consume biomass.

Carbon capture: Heating biomass such as wood pellets (right) in an oxygen-free environment produces char (left) and byproducts such as methane that can be burned.
Research shows that turning biomass into char and burying the char is a good way to avoid releasing greenhouse gases into the atmosphere.
Several states in this country and a number of Scandinavian countries are trying to supplant some coal-burning by burning biomass such as wood pellets and agricultural residue. Unlike coal, biomass is carbon-neutral, releasing only the carbon dioxide that the plants had absorbed in the first place.
But a new research paper published online in the journal Biomass and Bioenergy argues that the battle against global warming may be better served by instead heating the biomass in an oxygen-starved process called pyrolysis, extracting methane, hydrogen, and other byproducts for combustion, and burying the resulting carbon-rich char.

Turning Slash into Cash
A portable plant might make it economical to transform huge amounts of logging "waste" into energy -- right in the forest.

Really?
this is where the BIG money is until farmer's organisations get on the Terra preta bandwagon.
