Waste wood as biomass

Contamination issues
A high proportion of bark in the sawdust used to produce the pellets will lead to higher ash content. The presence of minerals such as heavy metals, high levels of alkali and alkaline earth metals, sulphur, etc. from the soil and air of the growth environment, or a range of potential contaminants from the use of recycled timber can potentially be an issue.

Calorific value
The mix of timber used, the presence of any additives such as binders, the quality of grinding and pressure used in production and hence final density, as well as the moisture content will all have an influence on the calorific value.

Mechanical durability
Wood pellets can absorb moisture from the air if stored in a damp environment, and this can lead to them becoming crumbly and breaking down to sawdust.  The mechanical durability of wood pellets is important, especially if they are to be subjected to more than a few handling steps.  This can particularly be the case with pellets imported from overseas which may have been subject to many handling processes during loading and unloading.
