>>>Also see other articles on Biochar , or Agrichar, in this
listserve last May, when this article came out
... Agrichar is the term not for the biomass fuel, but for what is
left over after the energy is removed: a charcoal-based soil
amendment. In simple terms, the agrichar process takes dry biomass of
any kind and bakes it in a kiln to produce charcoal. The process is
called pyrolysis. Various gases and bio-oils are driven off the
material and collected to use in heat or power generation. The
charcoal is buried in the ground, sequestering the carbon that the
growing plants had pulled out of the atmosphere. The end result is
increased soil fertility and an energy source with negative carbon
emissions.
