Co-generation dryers would improve the energy use of
sawmills. The heat demand from the drying kilns is sufficient
for drying all the side products from a sawmill, even if
the bark is dried and the sawmill produces high amounts of
side products [21]. Due to this, sawmills have the potential
to play a leading role in the market of processed wood fuel.
From an energy resource perspective, this, together with the
subject of transportation [31], indicate that the wood fuel
should be dried and compressed at the sawmill. Thus,
integration is a key issue for energy efficient drying and
pelletising.
