[Terrapreta] Another promising carbon capture technique

[Green Waste Recycle Yard]

This is very smart and cool. Could go hand in hand with pyrolysis plants,
and most certainly should be applied to existing cogen plants.

Here is a movie with a benchtop demonstration of the concept:

Being exothermic, there is also the potential for capturing the process heat
as well.

Carbon-negative energy revolution a step closer: Carbon8 Systems to capture
CO2 from biomass through carbonation
http://biopact.com/2008/01/carbon-negative-energy-revolution-step.html
By Biopact team(Biopact team) 

The bioenergy community is excited about a new start-up that could play a
key role in the mass introduction of carbon-negative bioenergy systems.
Scientists from the University of Greenwhich who formed Carbon8 Systems have
developed a technique that allows power producers to capture CO2 simply by
turning it into limestone via a carbonation process. If the system is
applied to biomass power plants instead of coal plants, the company says,
'negative emissions' are obtained. Negative emissions from energy means that
CO2 is pulled out of the atmosphere. What is more, for tropical and
subtropical countries that lack large limestone deposits - a key soil
amendment to make acidic soils more productive - the process could result in
an extremely important synergy that allows farmers to boost (energy) crop
yields.
