K. Kärhä
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...
