Abstract
The capabilities use of wood waste in the Ekaterinburg city, generated during the felling of trees and sanitation in the care of green plantations in the streets, parks, squares, forest parks was investigated in this study. In the cities at the moment, all the wood, that is removed from city streets turns into waste completely. Wood waste is brought to the landfill of solid household waste, and moreover sorting and evaluation of the quantitative composition of wood waste is not carried out. Several technical solutions that are used in different countries have been proposed for the energy use of wood waste: heat and electrical energy generation, liquid and solid biofuel production. An estimation of the energy potential of the city wood waste was made, for total and for produced heat and electrical energy based on modern engineering developments. According to our estimates total energy potential of wood waste in the city measure up more 340 thousand GJ per year.
Highlights
In Russia, the problem of utilization of wood waste in the forestry and woodworking industry, as well as wood waste generated during pruning trees and bushes on city streets and park zones, is one of the most urgent
In the municipal economy at the moment, all the wood that is removed from city streets, parks and squares is brought to the landfill of solid household waste, that is, it turns into waste completely
In addition to waste disposal in landfill, technical solutions exist for converting them into heat and electrical energy, as well as into other types of products
Summary
In Russia, the problem of utilization of wood waste in the forestry and woodworking industry, as well as wood waste generated during pruning trees and bushes on city streets and park zones, is one of the most urgent. It is so because at present more than a half of the tree biomass is lost with the existing methods of processing. In the cities at the moment, all the wood waste is brought to the landfill of solid household waste It is indicates a low level of technological processes of woodworking and ignoring existing opportunities for using wood waste from cities.
