Abstract

At the moment, we observe a situation of underutilization of woody biomass of the existing forest exploitation fund in the forestry sector of Russia. The key problem is the accumulation of wood waste. Vast resources of such wastes prevent the transformation of deciduous plantations into more valuable ones ‒ conifers, increase the fire hazard, create a base for the development of phyto-diseases and harmful insects, and expend a considerable amount of atmospheric oxygen in the process of decay. This problem can be solved with the use of thermochemical treatment of this type of wood waste. More often, this issue is an economically unviable approach of utilization. When processing wood pulp from crowns, many rival products can be obtained, which is profitable for forestry and wood processing enterprises in the Nizhny Novgorod region. The depth and direction of wood pulp processing are of great regional and national importance. The goal of research is to estimate the stock of wood waste from crowns, resulting cutting in forests of the Nizhny Novgorod region. The studies are carried out according to accepted methods for silvicultural and taxation works. The targets of research are the forest key areas of district and interdistrict forestries of the Nizhny Novgorod region. 78 sample plots are laid to determine the amount of wood waste in key areas. The distribution of the resource potential of wood waste in the forestry areas of the Nizhny Novgorod region is established: the maximum resource is formed in the territory of the Privetluzhskiy spruce and fir forest area ‒ 209.88 thousand m³; in the pine and broadleaved forest area ‒ 157.32 thousand m³; in the Privolzhskiy forest area ‒ 130.35 thousand m³. The minimum resource is concentrated in the broadleaved forest area ‒ 91.80 thousand m³. The information received about the resource potential of wood waste from crowns, will allow organizing production capacity for their processing. Research materials can serve as a basis for forest inventory in the territory of the Nizhny Novgorod region.
