Charcoal fines refer to the small particles or dust that are produced during the process of making charcoal. Charcoal itself is a solid fuel obtained from heating wood or other organic materials in the absence of oxygen, a process known as pyrolysis.
During the charcoal production process, wood is heated in a controlled environment, and volatile compounds are released, leaving behind carbon-rich charcoal. However, not all the wood is converted into charcoal, and some portion is transformed into small particles or fines.
