Abstract
The article presents materials on the prospects of processing wood waste into high-strength structural cellulose material using alkaline processing of raw materials followed by hot pressing. Materials on the study of the cellulose-lignin complex and non-structural components of wood on the example of coniferous plants of various life conditions, including dead wood, are presented. Differences in the content of extractive substances (non-structural components) in individuals of different living conditions, which have a significant impact on the chemical treatment of wood, were revealed. The possibility of using white rotting wood-destroying fungi for partial delignification of wood is considered. The study was carried out with the financial support of the RFBR grant No. 19-04-00353 A.

Wood is a cheap and widespread natural material, and it has been used as construction material in everyday life for ages
Summary
Polymeric and metal construction materials with high physical and mechanical characteristics have either large weight and suffer from environmental hazards (metal corrosion), or suffer from complex production processes and, high cost (polymeric). Physical and mechanical properties of natural wood are inferior to many modern construction materials. Preliminary processing with steam, heat, ammonia, or cold reduction with subsequent packing led to the increase of natural wood mechanical properties [1,2,3,4]. With regard of active development of construction industry and farsighted use of the existing resources, the goal of our study is developing new technical solutions in the field of wood processing, allowing the use of raw materials base to the full extent, including the active involvement of wood waste
