Complex processing of wood debarking waste as a factor of environmental safety

Abstract

In recent decades, the development of a modern industrial enterprise is impossible without considering the issue of complex processing or disposal of waste of the main production. This issue is very acute for the enterprises of the wood processing industry. The processing of wood waste should be considered not only as a factor of rational and environmentally safe use of forests, but also as a factor providing comprehensive processing of wood without increasing the amount of its harvesting and allowing production of new environmentally safe materials in constructing or other purposes. The paper presents the technological aspects of the production of innovative board composite materials made without binders based on debarking waste of coniferous wood raw materials and the studies` results of its operational properties. The produced composite is completely eco-friendly and biodegradable. The manufacturing technology consists of the mechanical activation of the tree bark in a hydrodynamic dispersant. Thanks to this treatment, the bark particles change their microstructure, acquire a large number of active centers and autocoherent properties, which make it possible to create slab materials based on it without introducing binding components and various types of additives into the composition.
