【 摘 要 】

Current trends involve the use of waste, what makes the enterprise more environmentally friendly. One of the direction is using woodworking wastes for receiving building materials. Before obtaining the necessary building material sawdust is subjected to pretreatment – to improve the technical characteristics of the future product. This article describes the method of obtaining insulation material from sawdust with special pretreatment: processing in cavitator and then pressing. Comparative characteristics of heat-insulating properties with analogues are given, advantages and disadvantages are revealed. Using sawdust as raw material for production ecological heat-insulating building materials allows to create closed production cycle. Besides this method can significantly decrease negative influence of woodwork production on the environment. As conclusions, it is proposed to use hydrodynamic processing as a method to improve the technical characteristics of the product without significantly increasing the cost of the material.
