The Soil Fertility Project is an interesting project that attempts to use biochar to address soil fertility and climate change both in Wales in weed eradication 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.
