A gasifier can also be used to make BIOCHAR. Here are some simple design examples for charcoal/biochar-producing biomass gasifiers:
- 50 kilowatt wood pellet gasifier
- Charcoal kiln at A.R.T.I.
- Folke Günther's design: "the simplest of the simple - a two-barrel charcoal retort"
- Tom Reed's TurboStove
