Method for conversion of wet woody biomass, including wood waste originating from landscape maintenance, into high-grade fuel pellets, the method comprising the steps of: - providing a quantity or a flow of woody biomass; - basic reduction of the ingredients of the woody biomass into coarse chips with a maximum size of 50 mm for example; - wet milling the coarse chips into wet fine chips; - drying of the wet fine chips into dry fine chips; - splitting of the dry fine chips into different fractions, including a first fraction I having a cross section of 1 mm maximum, a second fraction II having a cross section of 2 - 4 mm, a third fraction III having a cross section of 1 - 2 mm and a forth fraction IV having a cross section of greater than 4 mm; - removal of the first fraction I, for example by combustion for the purpose of the above-mentioned drying of the wet fine chips, storage of the second fraction II, feeding of the third fraction III to a sorting device and feeding of the forth fraction IV to a reduction device; - wherein the sorting device sorts the third fraction III into, a first sub-fraction IIIa having a density sg 1, which is lower than the density of the target pellet material, a second sub-fraction IIIb having a density sg 2, which corresponds to the density of the target pellet material, and a third sub-fraction IIIc having a density sg 3, which is higher than the density of the target pellet material, wherein the first sub-fraction IIIa and the third sub-fraction IIIc are removed and the second sub-fraction IIIb is added to the stored second fraction II of the dry fine chips; - compressing of the stored dry fine chips into pellets, cooling-down the pellets in order to be suitable for use as a high-grade fuel. - providing a quantity or a flow of woody biomass; - basic reduction of the ingredients of the woody biomass into coarse chips with a maximum size of 50 mm for example; - wet milling the coarse chips into wet fine chips; - drying of the wet fine chips into dry fine chips; - splitting of the dry fine chips into different fractions, including a first fraction I having a cross section of 1 mm maximum, a second fraction II having a cross section of 2 - 4 mm, a third fraction III having a cross section of 1 - 2 mm and a forth fraction IV having a cross section of greater than 4 mm; - removal of the first fraction I, for example by combustion for the purpose of the above-mentioned drying of the wet fine chips, storage of the second fraction II, feeding of the third fraction III to a sorting device and feeding of the forth fraction IV to a reduction device; - wherein the sorting device sorts the third fraction III into, a first sub-fraction IIIa having a density sg 1, which is lower than the density of the target pellet material, a second sub-fraction IIIb having a density sg 2, which corresponds to the density of the target pellet material, and a third sub-fraction IIIc having a density sg 3, which is higher than the density of the target pellet material, wherein the first sub-fraction IIIa and the third sub-fraction IIIc are removed and the second sub-fraction IIIb is added to the stored second fraction II of the dry fine chips; - compressing of the stored dry fine chips into pellets, cooling-down the pellets in order to be suitable for use as a high-grade fuel.
