How Green Man Char Wood Vinegar is made

Wood vinegar is made by heating organic biomass material in an environment that is oxygen reduced. This leads to the materials thermal decomposition along with the release of gases. The exhaust smoke is then cooled into a liquid. This liquid is then separated, and refined into wood vinegar.
