Abstract:
The state of the art of stump wood harvesting for energy in Finland is described in this conference paper. In 2010, the consumption of stump wood for energy generation was equivalent to 2 TWh in Finland. Currently, stump harvesting operations are primarily directed at Norway spruce (Picea abies) dominated final cutting sites. The typical stump wood removal is 150–180 MWh/ha. Stumps are extracted by tracked excavators equipped with a stump lifting head. Excavators both under and over 20 tonnes are used. Site preparation for stand regeneration is very often integrated with stump extraction. The stumps are hauled to roadside landings by forwarders. Longdistance transportation of stumps is carried out by so-called energy wood trucks. The majority of stump wood chips used for energy generation are produced at power plants by powerful crushers. The comminution of stumps is performed by heavy mobile or fixed stationary crushers.
