Abstract

Method of dry separation of inner and outer bark from debarking wastes has been developed and proposed. The technology of complex utilization of spruce dry debarking wastes has been developed resulting in producing bark extract, fiber bast semi-finished product and nutrient yeast from the inner bark and burning the outer bark for producing process steam. Optimum operating practice for producing bark extract and fiber bast semi-finished product from the inner bark without using chemical agents has been set.
