What does one do with all the recycled timber in the urban environment? With a bio char maker you can make Charcoal as well as an inexpensive stove. We made one at the Woodstock to recycle all the off-cuts we collect. Please note that some timber has been impregnated with flame retardant and is poisonous when burnt. In particular we note that wood from timber palettes should never be used for cooking or fires to warm an environment. We made this fun movie to demonstrate the Bio Char maker.
