About Wood Vinegar
Wood vinegar is a light brownish liquid that is produced through the natural act of carbonization. This occurs when organic biomass material is heated in an oxygen reduced environment leading to the thermal decomposition of materials and release of volatile elements. The exhaust from this char production is then condensed into a liquid. The condensate then further separates into wood vinegar, bio-oil, and tar.
Wood vinegar has a low pH (around 3) and contains more than 200 organic compounds, which include:
These various elements work synergistically for a greater outcome. The composition and properties of wood vinegar depend on feed source materials as well as the method (time/temperature) of pyrolysis.
Wood vinegar has a long history of successful use throughout Asia for the replacement of expensive fossil derived agriculture chemicals. There is evidence of the successful use dating back to thousands of years in the Amazon and even in the 1900s when substantial factories commercially produced wood vinegar with creosote as a source of acetic acid.
