Wood pellets

Bioenergy > Biomass > Wood > Wood pellets
Wood pellets are generally produced out of wood waste such as sawdust and shavings. The raw material is dried, mechanically fractioned to size and thereafter extruded under intense pressure into pellets. In the process the raw material is densified approximately 3.7 times (FAO (.doc)). The product produced in Western Canada has a bulk density of approximately 705 kg/m3 and a bulk stowage factor of approximately 52-56 ft3/metric tonne.
Wood pellets are primarily used as a fuel and have a calorific (heat) value of around 5 MWh/metric tonne (18 GJ/metric tonne) which is approximately half that of fuel oil. In North America the wood pellets are used in wood pellet stoves and fireplaces. In Europe, particularly Scandinavia, the bulk of the pellets produced are used as fuel in central heating stations supplying heat for entire communities or even entire cities.
