Abstract
The creation of new thermal insulation materials in the conditions of critical rise in the cost of energy resources is due to the energy saving policy. The most important characteristics of such materials are energy efficiency and effectiveness and environmental friendliness. Scientists of the Siberian Federal University developed a thermal insulation material based on waste wood processing industry. A distinctive feature of the proposed material is cavitation processing of raw materials. The production technology is the following: wood waste as part of the aqueous suspension go through cavitation treatment with the help of a high-speed mixing plant, then the suspension is kept in room conditions for a day, after that the raw material is subjected to hot pressing. As a result of such sequence of technological actions we get the competitive heat-insulating material on heat engineering qualities close to analogues, but with much lower prime cost of its production. Another important feature of this material is the ability to control its final qualities, depending on the mode and duration of cavitation processing.
Highlights
Modern trends in the development of recycling technologies involve the use of waste, which is determined by the necessity to reduce the anthropogenic load and is an economically reasonable solution from the point of view of resource saving

It is proposed to calculate the cost of construction of walls using various thermal insulation materials, depending on a particular material and we take into account structural and waterproofing elements that make up the wall
Summary
Modern trends in the development of recycling technologies involve the use of waste, which is determined by the necessity to reduce the anthropogenic load and is an economically reasonable solution from the point of view of resource saving. One of the areas of recycling is the use of waste wood processing industry to produce construction products and materials. The result of the production process is a new thermal insulation material from woodworking waste. 2. Literature review Trends of ecologization of production and development of recycling technologies were considered in works of domestic and foreign authors A. Danilova [6] proposed the use of wood waste as an energy resource, while other authors 4. Technology During the research, all parameters of the technological process affecting the characteristics and quality of the final product were determined experimentally, as a result, a technological map was developed for the production of thermal insulation material based on cavitation-modified waste of wood processing production. The main cost items were the cost of materials, machines and mechanisms and wages
