Use of wood biomass of forests for energy purposes is a structural component of organization of a system of sustainable use of forest resources. In this context, within the framework of this research, a quantitative assessment of annual energy potential of wood biomass in forests of Kyiv region is proposed, which takes into account conceptual foundations of sustainable forest management. As a result of the research, we established quantitative indices of energy content in live biomass of forest stands of the studied region, as well as their energy productivity. In general, more than 1960 PJ of energy is accumulated in stands of the region, and their energy productivity is about 112 PJ·year-1. At the same time, hardwood stands are characterized by the highest energy productivity – 235 PJ·ha-1·year-1. We calculated five types of energy potential of wood biomass that take into account aspects of environmental safety, economic development of the region and social features of life of local communities. The quantitative value of the annual energy potential of wood biomass in forests of Kyiv region varies from 18.4 to 8.4 PJ, depending on its type. [ABSTRACT FROM AUTHOR]

The use of wastes of wood processing for energy purposes is a structural component for organization of the system of sustainable use of forest resources. In this context, within the scope of this work, the terminological and conceptual tools and methods for estimating the energy potential of biomass of the wastes of wood processing (forest wood wastes) are suggested, which are in line with the conceptual foundations of sustainable forest management. In the course of elaborating of the methodological approaches to estimating the energy potential of wastes of wood processing biomass, mathematical dependencies were suggested for the estimation of the five types of their potential: theoretically possible, technically accessible, ecologically safe, economically profitable, and socially conditioned ones. These types methodologically make allowance for the principles of sustainable forest management, that is, combining issues of environmental security and economic development of the regions, as well as taking into account the social characteristics of the lives of local communities. Suggested methodology allows estimating both the future (anticipated) potential of the forestry wood waste biomass as well as the present one. [ABSTRACT FROM AUTHOR]
