Wood Vinegar

Wood Vinegar, or pyroligneous acid - sometimes known as condensate - is a dark liquid produced from the smoke and emissions generated by the pyrolysis (burning/charring) of oil mallee biomass. Smoke and emissions are drawn from the pyrolysis plant combustion chamber and channelled through a series of pipes and cooling chambers where they are condensed to generate this amazing natural product.

Wood Vinegar’s Structure

Pyroligneous acid is a crude, condensed and highly oxygenated organic liquid which is a by-product of biomass pyrolysis. It mainly comprises aliphatic, aromatic, and naphthenic hydrocarbons with other oxygenated compounds such as alcohols, aldehydes, ketones, furans, acids, phenols and ethers.

Its uses

Fasera will produce about 900 tonnes of wood vinegar annually. Wood vinegar contains ~200 organic compounds and together with biochar, sales of wood vinegar are becoming a significant revenue driver for the business.

Pyroligneous acid exhibits anti-oxidant and chemical scavenging properties and has been used in agriculture for a wide range of applications. An all natural product, wood vinegar can be used as a soil bio-stimulant at low rates of application. With its high content of organic compounds, it can be used to improve soils and promote seed germination and plant growth. Natural Wood Vinegar provides significant environmental benefits when replacing traditional chemicals.

The organic compounds found in wood vinegar can also be used as an effective anti-microbial agent or as an insecticide. When diluted, it is a natural bio-herbicide and is effective in reducing or eliminating the growth of weeds/unwanted plants. When diluted, it is also an effective bio-pesticide. Wood vinegar is a potentially high-value market replacement for chemical pesticides and herbicides, although further market development and research is required. It is potentially a very lucrative market, with equally significant potential environmental and economic benefits.

How it’s made

The spent (used) biomass after steam distillation to produce eucalyptus oil and the woody biomass from mature trees is fed into the pyrolysis plant to produce biochar.

Smoke and other emissions from the pyrolysis of our biomass are extracted from the combustion chmaber and condensed to produce wood vinegar.
Wood vinegar can be generated at a rate of 2L/minute per char machine depending on the source biomass. Fasera is planning on commissioning two additional char machines to have three operational by 2027.

Watch our production process

The production of wood vinegar from the condensation of smoke and organic compounds that otherwise would be emitted represents just one element of the integrated portfolio of products we’ve developed whilst actively improving environmental outcomes.

How to purchase

At Fasera we grow, harvest and process biomass from oil mallee tree plantations. The pyrolysis of biomass produces a range of products including wood vinegar. Wood vinegar and our wider product range is available for either wholesale purchase by businesses or retailers, or retail purchase by individual customers.
