Soil Fertility Projects
In the Indian project ( http://www.soilfertilityproject.com/Soil_Fertility/Indian_Project.html). The participants started by using the Anila stove to product biochar, but found that it was unworkable. Now they are using a digestor to process wet waste, get some energy, and use the slurry for fertilizer. They are also using a small BiG Char unit to process green waste into biochar.
in Wales ( http://www.soilfertilityproject.com/Soil_Fertility/UK_Project.html ) they are using biochar to create a useful product out of larch trees killed by hytophthora ramorum. The biochar helps restore the soil, and it prevents the CO2 release that would normally occur from burning piles of diseased wood.
There's lots of great information on their web site: http://www.soilfertilityproject.com
