METHOD FOR UTILIZATION OF FOREST RESIDUES Russian patent published in 2008 - IPC A01G23/00 A01G23/02 

FIELD: process for utilization of forest residues immediately at production sites in commercial wood harvesting.

SUBSTANCE: method involves extracting stumps and roots of felled trees from ground; crosscutting stumps into parts; collecting crosscut stumps, roots, branches and tops of felled trees and grinding the above; sorting out ground mass and separating particles having sizes of at least 10 mm from main mass; drying main mass to moisture content of 8-10% and pressing to melting temperature of wood resin for forming wood briquettes with the use of its resin; directing part of ground mass separated from main mass for dry distillation in order to obtain distillation products; utilizing thermal energy generated during dry distillation process for drying of main ground mass before pressing process, and directing gas into internal combustion engines for driving of forest residue regeneration complex units.

EFFECT: provision for complete forest residue processing cycle allowing wide range of useful products to be manufactured for various branches of industry, full clearing of cuttings from forest residues, and preparing of soil for forest restoration.
