Wood vinegar (pyroligneous acid) is a liquid byproduct obtained during biomass pyrolysis. It contains a complex mixture of organic compounds, including acetic acid, methanol, and various phenols, contributing to its distinct smoky odour and beneficial properties. Wood vinegar is recognised for its versatility, finding applications in agriculture, livestock, environmental management, and beyond. 

Applications Across Industries: 

• Agriculture: Wood vinegar is highly valued for its multiple functions. In various concentrations, it acts as a plant germination accelerant, stimulating faster and more uniform seedling emergence. It is also a natural pesticide, effectively repelling pests and reducing reliance on chemical treatments. Wood vinegar improves soil quality by enhancing microbial activity and nutrient availability when used as a fertiliser. Applied as a foliar spray, it can increase fruits' flavour and sugar content while stimulating overall plant metabolism.   

• Livestock: In livestock management, wood vinegar is utilised as a feed supplement to enhance animal health and productivity. It improves animal digestion and nutrient absorption, leading to better growth rates and higher-quality meat production. Wood vinegar is also used to treat animal housing, reduce odours, and control pests such as flies, mites and rodents, thereby improving the overall environment for livestock. 

• Environmental Management: Wood vinegar plays a significant role in environmental remediation and waste management. It is used in composting to accelerate the breakdown of organic matter and improve compost quality. Its antimicrobial properties help control pathogens, making the composting process more efficient and safer. In waste treatment, wood vinegar is employed to reduce odours and enhance the degradation of organic waste.   

• Construction: In the construction industry, wood vinegar is used as a natural preservative for wood products. When applied to timber, it helps protect against decay, pests, and fungal growth, extending the lifespan of wood materials. This natural preservation method offers an eco-friendly alternative to chemical wood treatments, making it popular in sustainable building practices. 

• Decontamination: Wood vinegar's antimicrobial properties make it effective in decontamination processes. It can disinfect soil and water, reducing harmful bacteria and other pathogens. Wood vinegar is also applied in air purification systems to neutralise odours and pollutants, creating healthier environments. 

• Pharmaceuticals and Personal Care: Wood vinegar is explored for its potential health benefits in the pharmaceutical and personal care industries. It is used in various traditional medicines and natural health products for its detoxifying and antimicrobial properties. Additionally, wood vinegar is an ingredient in natural skincare products, valued for their ability to cleanse and tone the skin. 

• Carbon Credits and Sustainability: The production and use of wood vinegar play a significant role in promoting sustainability by reducing dependence on synthetic chemicals and enhancing organic farming practices. While carbon credit programs have yet to officially recognise wood vinegar, it is increasingly viewed as a potential means to monetise its environmental benefits, especially in carbon sequestration and the reduction of emissions from chemical fertilisers and pesticides.
