The problem of obtaining environmentally friendly building materials on the basis of wood processing waste is very actual. Creation of high technologies in the production of wood composite materials with a wide raw material base is possible only with the use of the latest achievements of physics, chemistry and microbiology. Processing of wood raw materials allowed to obtain construction materials meeting the requirements of the standard, even on the basis of widespread waste wood processing - sawdust. Pilot samples of biologically activated concrete based on sawdust were obtained and their basic physical and mechanical properties were determined. The project of technological scheme for the production of biologically activated concrete based on sawdust and the variant of using this material as an insulator of a laminated panel have been developed.
