Biochar for Environment and Development
I liked to sections on biochar prep and blends etc, but the section on production systems lacked with regards to modern techniques and improved emission control designs. For those interested in making biochar use either a TLUD gasifier or a cone burner as a starting point. Retorts in general from my first hand experience are explosions waiting to happen. If your system at any stage of production generates visible smoke you need to better focus on your design and maybe look at the moisture content of your feedstock. If biochar production generates any visible smoke during production it is NOT an environmentally beneficial process or product.
For those interested in what I am doing. I have been really busy hiding in my workshop developing two new biochar making systems. I hope to bring you some updates and news in the next two weeks.
