Pyroligneous Acid (wood vinegar)

Description

ATTENTION:

We have made significant further progresses in our patented grinding pyrolysis technology. We are now able to reduce the prices of our wood vinegar to share the benefits of our technology advances with our customers!

Renergi’s pyroligneous acid (wood vinegar) is produced from sustainably sourced forestry and plantation residue biomass using Renergi’s patented grinding pyrolysis technology. It is carbon-rich natural organic acid concentrate containing hundreds of beneficial organic compounds that are formed during thermal breakdown of biomass. No other chemicals are added. It is proving to be a game-changer for growers serious about innovation and improving the health and quality of their soils and crops.  Through our groundbreaking patented technology, Renergi has overcome the constraints of supply availability, price, and producing in a highly controlled way resulting in a consistent end product. Renergi can produce in a week what most competitors can only produce in a year.

What Is It?

Pyroligneous Acid (wood vinegar) is produced through condensing of various bio-gases and bio-oils from a process called pyrolysis: the carbonisation of biomass under conditions of relatively high heat and low or no oxygen. It is the process that also produces the co-product of biochar. It contains a complex mix of biologically active compounds, including but not limited to: organic acid (carboxylic), phenolics, aldehydes, ketones, furans, karrikins, and sugar-type compounds. These combine to provide different beneficial growth activating and plant health functions, such as improving photosynthesis, nutrient and water adsorption, seed germination (karrikins), and antioxidant, disinfectant and antibacterial properties. It offers growers a natural low-harm and sustainable alternative to boost plant vigour and increase resilience to pests, disease, and drought, and enhance soil biology for healthier and more productive crops. It can be used as a foliar spray, soil drench, as a germinator or seed soak, or combined with or alongside other products when seeding.

Key Properties:

​​Renergi’s Pyroligneous Acid (wood Vinegar) generally has a pH of between 3 and 3.2, with a composition typically made up of several groups of organic compounds:

Carboxylic acids (principally acetic): the source of Pyrolignic’s acidity and of the name “wood vinegar” — short-chain organic acids that soil microbes readily metabolise as a labile carbon source.

Phenolics: provide a wide range of benefits, from providing disinfectant and antioxidant properties to providing a major function to Pyrolignic’s ability to complex nutrients in a highly plant-available form.

Aldehydes, Ketones and Furans: are primary drivers of foreign antimicrobial activity antifungal activity in published wood vinegar research.

Karrikins: Plant growth regulators found in biomass smoke in small (parts per million) amounts are highly effective at triggering and improving seed germination. The name ‘Karrikins’ comes from the Noongar (WA) word “karrik”, meaning smoke. Karrikins are required for certain Australian native seeds to germinate, but the benefits apply to all seed germination.

The Renergi Difference:

The composition of pyroligneous acid (wood vinegar) — and therefore what it does to plants — is determined largely by pyrolysis technology and conditions. Too little secondary/tertiary pyrolysis reaction leaves heavy, biopolymer-like liquids that don’t form good wood vinegar; too much pushes products toward tar and polycyclic aromatic hydrocarbons (PAHs). Renergi’s patented technology is engineered to sit between these extremes: forming small, water-soluble organics (supporting high organic content) while limiting PAH and growth-inhibitory species. The result is a wood vinegar that remains safe for plants at lower dilutions than many generic and inconsistently produced wood vinegar products. Herbicidal effects are possible at full concentration on softer plants, or when purposefully combined with other products. With a pH of ~3 in its concentrated form, there is the potential for leaf burn, however, complete herbicidal effects not expected on most plants even at full concentration or at high concentrations/low dilutions rates.
