I have just gone through the literature stating that torrefied wood is not biodegradable I am not understanding why it is so? Could anybody explain on this. I would like to know is there any way to make it biodegradable?
Torrefied wood is a renewable, carbon-neutral energy source that is more energy dense than wood and almost as dense as coal. Torrefied wood is created from biomass material that goes through a process called torrefaction.

The pyrolysis process in the absence of oxygen that occurs in this process produces a biodagradable product from wood. The chemical change of the polymers of wood cells (basically, cellulose, hemicellulose and lignin) and the hydrophobicity of torrefied wood does not allow that this be degraded by the organisms
Hello! Due to the high temperatures in the wood processing hemicellulose (wood sugar) decomposes. Low equilibrium moisture content. This eliminates the conditions for the emergence and propagation of fungus and microorganisms.
