New biotechnologies offer new possibilities to utilise forest biomass. These result in increasing demand for wood and have an impact on the existing wood resources and wood flows. The objective of this research is to identify and quantify actual material and energy wood flows to determine the main uses of wood in the context of bioeconomy in Slovakia. The research presents a comprehensive model of wood flows between the resources and utilisation of wood in different primary wood consuming sectors. The wood resources balance model covers all possible applications of wood in various forms, including flows of wood material and wood residues for industrial and energy purposes. To develop a balance model collection of data through the empirical research was carried out. Considering the cascade use of wood we were able to calculate respective cascade coefficients and determine the final level of wood consumption in different end-use sectors using wood as a material and as a source of energy production. It follows for the results that sawmilling industry consumed 30%, wood based panels industry 13%, pulp and paper industry 17%, energy sector 40% of the total domestic wood consumption. Taking into account wood cascading principles through repeated utilisation of wood residues and energy flows the total use of wood increased 1.46 times.
