We are facing a big challenge.

We have to produce more wood

pellets, when there is less mill

residues available….

Challenges Vs Standards

• Physical

• Humidity

• Contamination

• Ash content

• Calorific value (loss)

Physical Challenges:

Residues Biomass

-Known composition -Vary at each site

-One or few species -Multiple species

Humidity levels::

Residues Biomass

-Dry or known levels -Vary constantly

-Season

-Climate

-Site

Residues Biomass

Usually clean Higher possibility of:

-Rocks

-Minerals-Metal

-Other 

Contamination:

 Ash content :

Residues Biomass

-Generally low -Higher because of bark

and contaminants

Conclusion:

 Also we must understand that boilers and

stoves, will need to adapt to higher ash

content, not the opposite !

We will need projects to arise, in order to

prove that biomass can be used as aclean fuel source.
