Pakietowanie pozostałości zrębowych nowym sposobem wykorzystania biomasy leśnej do celów energetycznych

Woody fuels are perceived as an important potential renewable source of energy in Poland. With about 25 thousand ha of clear−cut every year, it is possible to collect over million tons of woody fuels in form of logging residues, which is usually left behind after timber and industrial wood have been taken away. The technology using slash bundlers for bundling logging residues is an interesting option to produce a woody fuel ready for burning. Logging residues bundles differ in their dimensions and weight depending on the bundling machine used for the operation. As the technology utilises green branches and tree tops for producing bundles, it may lead to losses in the amount of certain chemical elements in the forest site thus negatively affecting the future forest generations. The complexity of the problem calls for intensive research into the problem of using logging residues as a source of energy.
