Make Your Own Biochar

0804burning2net Friend of re:char and biochar researcher Folke G√ľnther provides handy and easy-to-follow instructions on how to construct a simple, two-barrel biomass pyrolyzer at home. Folke’s Simple Charcoal Retort consists of two nested steel barrels, and can be made using recycled or locally-available materials.

To build your own, visit Folke’s website.
