The traditional method of making charcoal entails burning wood in an airless kiln. As the smoke in the kiln cools down, it turns to vapor and then to liquid-pyroligneous acid or “wood vinegar”.
The uses of wood vinegar:
- Antibacterial agent that sterilize and disinfection
- Deodorize bad smell
- Killing germs of pets and insect repellent
- As a fertilizer to make the plant better growth
- The PH is 2 ~ 3, dilute with water
Wood vinegar contains more than 200 components, including acetic acid, methyl alcohol, acetone, and other organics substances.
