Pyroligneous Acid

Pyroligneous Acid (PA), also called Wood Vinegar, is a natural amber liquid produced through the natural act of carbonisation during charcoal/biochar production.
PA is acidic with a low pH of around 2-3 and contains a multitude of organic compounds. The composition and properties of wood vinegar depend on feed source materials as well as the method (time/temperature) of pyrolysis. It is proposed that various elements of the wood vinegar work synergistically for a better outcome as opposed to the specific effectiveness of a certain element, or the whole is greater than the sum of its parts.


How it is made:
Organic biomass is heated in an oxygen reduced environment leading to the thermal decomposition of materials and release of gases (called pyrolysis) – this exhaust smoke is condensed (cooled) into a liquid. The condensate then further separates and is refined into Tar, Wood Vinegar and Bio-Oil.
Production equipment can vary from basic metal drums or in ground fire pits covered in clay mud with cooled bamboo chimneys to state of the art industrial processors that are completely controlled continuous biomass converters.


Quick History:
Charcoal production for farming use dating back thousands of years to the Amazon basin’s black terra preta earth, the ancient Egyptians practiced wood distillation by collecting tar and pyroligneous acid for their embalming industry. In the 19th Century and early 20th Century wood distillation was still profitable for producing soluble tar, pitch, creosote oil, other chemicals like acetic acid and acetone. The wood distillation industry declined in the 1930s due to the advent of the petrochemical industry and its lower price products.
Japan and throughout Asia has used Wood Vinegar successfully for decades with all sorts of uses and as a replacement of synthetic agri-chemicals. The food industry continues to use pyroligneous acid extracts as a smoke flavour additive to foods, meats and sauces.
There are many claimed uses for Wood Vinegar but the main commercial applications are: a food additive for enhanced smoke flavouring, industrial source for extracting other chemicals like acetic acid, tar and creosote production, water treatment, animal husbandry, human medicinal purposes and agriculture.
In Australia Wood Vinegar for agriculture is in its infancy, but is gaining momentum with many varied crops under trial and some moving into the fourth continuous year of application showing positive results.


Our process:
PA can be made from many biomass resources and processor types which will vary the composition of the end product. Our product is 100% Australian Made and produced from sustainable sources of biomass with the most efficient and controlled production methods available.
The natural feedstock material is all that is used in production, with the heat of process also supplied directly from the feedstock itself. After pyrolysis the wood distillate is settled for several months before processed and blended through our customised filtering plant producing a consistent high quality product with dependable results.


WV for Agriculture:
We believe that Wood Vinegar can bring substantial benefits to the Australian agricultural sector. It is a high density liquid with good economic freight costs versus coverage that fits into existing supply chain and on farm infrastructure. There is a growing organic and sustainable supply source from an emerging char production industry allowing a reduced dependency on limited expensive agrichemicals. The production is energy efficient and sustainable with further environmental benefits.
The extensive use of Wood Vinegar for agriculture throughout other countries for many decades along with positive trial results leads to a product that can potentially be farm input cost neutral or even negative while improving production results.
There are many varied possible uses for wood vinegar, so when designing your application and projected outcomes we recommend considering the following points.

• Wood Vinegar is unique and should not be considered as a stand-alone direct replacement for other agrichemicals – it is beneficial to think of Wood Vinegar as an “enhancer and penetrant” which can help the plant uptake of other existing chemicals with direct plant and soil improvements.
• Wood Vinegar is not a traditional fertiliser having low NPK levels
• When applying you need to discover the correct balance of quantity used for increased yield versus costs for the best financial return, this may vary with application and will require specific testing.
• Wood Vinegar used alone as a stimulant for seed germination has shown improved strike rate and time for varied species.
• Wood Vinegar should always be used diluted and strength will vary between foliar and soil application along with frequency of application.
• Longer term regular use has shown signs of much improved plant and soil health and ability to naturally protect themselves


Independent Research Shows Beneficial Use for the following Agricultural Applications:

Soil Application – Proven to increase microbial activity – healthy soils are critical to good crop performances where the Bacteria, Fungi and other Microbes unlock existing and added soil nutrients and make available for plant uptake. The more efficient conversion of available soil nutrients and a reduction in leaching can mean a reduction in synthetic chemicals and associated damaging effects, creating more sustainable soil health.


Foliar Application – Improved plant health, darker green leaves for better photosynthesis and increased sugar conversion for soil microbes, thicker and stronger stems, higher growth rates and yields, increased fruit sugar content, naturally more resistant to disease


Improves Efficacy – Several studies have shown using PA mixed with other applications can reduced agrochemical volume with the same or improved results, saving money and reducing indirect damage to soil health by excessive synthetic chemical applications


Seed Germination – Everyone is aware of the exceptional re-growth seen after native bush fires triggered by the heat and smoke chemicals that are contained within wood vinegar. We as well as others have done multiple germination trials with advantageous results


Composting – The benefit of composting is well documented, adding PA to the composting process and increasing the microbial activity helps speed up the process and reduce nitrogen gas losses for an improved product


Animal Stockfeed – Pyroligneous Acid has shown benefits to chicken health, meat and egg production. Some research into pig production, feed efficiency and replacement of antibiotics has shown positive results.
