The paper contains research results into the time consumption and costs of fuel woody biomass production, in the form of bundles and chips from logging residues. The tests were conducted in adult pine stands and machine technologies for wood harvesting and extraction were used. The share of logging residues in the total tree biomass was assessed based on measurements carried out on three experimental plots in adult pine stands. The costs calculations contained fixed and variable cost categories. The share of the woody biomass which forms logging residues in the total above-ground tree biomass was 15%. The time consumptions of the energy wood harvesting, using machine technologies, were 0.447 h/m3 for wood chips and 0.481 h/m3 for residue bundles, and the costs amounted to 53 PLN/m3 and 70 PLN/m3, respectively.
