UBI 350 BLACK is the new GREEN W Australia
Paul Blackwell, because of his interest in improving agricultural soils in Western Australia and reducing the CO2 foot print of agricultural operations through the incorporation of biochar in the soil has initiated an UBI 350 site. He build and tested a horizontal “oil drum” oven.
We look forward to many more ovens at this site as Paul continues to work with farmers in the area.
With these first two UBI 350 sites (W Australia and Ulaanbaatar) we can get a feel for the range of size of possible low tech biochar ovens, from small cans for model ‘get acquainted’ test ovens producing enough biochar for a little enhanced potting soil - to a large barrel ovens capable of producing a significant amount of biochar for soil enhancement. While both these sites are connected with serious on-going soil improvement projects, we would also like to encourage ordinary individuals to try their hand at it. It’s an excellent way to get acquainted first hand with biochar production and its potential while at the same time spreading the 350 word to others in your community and the role low tech biochar can play in global warming amelioration, soil improvement and general sustainability.

Photo 3. The front of the insulation housing is in place to increase efficiency by capturing more of the heat energy for the process of reducing the biomass to biochar. Additional efficiency could be gained by utilizing ‘down stream’ heat in drying biomass or heating water.
