Systematization of wood waste - the basis of their effective use

Abstract

Based on the results of a detailed analysis of literature sources, it was established that the industrial use of additional wood reserves is not only a significant increase in the raw material base for the woodworking industry, but will also become a necessity for environmental and economic reasons in the near future. After studying the state of the issue, the systematization of wood waste by origin as an additional raw material for processing in the woodworking industry was developed and proposed. It was found that potential sources of additional raw materials can be: logging waste (stumps and roots, knots and branches, tops and cuttings, thin-sized and substandard trees); post-production waste (sawdust and shavings, bars and slats, saws and burrs, trimmings and sawdust, grinding powder and screenings); post-consumer wood (PCW). The areas of suitability for the use of waste in certain industries are substantiated and proposed, as well as grouped by their qualitative characteristics for effective use. The main trends in the use of wood waste are outlined. It has been found that the issue of using used wood in Ukraine can be solved by solving three main problems: Technical and technological study of the suitability of individual wooden products and used wood for their repeated use as technological raw materials for wooden boards or as energy fuel. Equipment and technology for processing used wood and bringing it to the state required by plate manufacturers or the energy industry (power industry). Introduction of appropriate legislation in the field of management of wood waste and used wood products. Measures and ways, a concept and a strategy of using additional wood resources, which will ensure the efficiency of material or energy use, have been developed and proposed.
