Currently, the use of technogenic raw materials, including wood waste is one of the trends in manufacturing of building materials. This is due to the limited resources, the need for long-distance transportation, the high material and energy cost of some technological processes of raw materials extraction and processing. All of them greatly hamper the development of the industry of building materials based on natural resources. Different cellulosic fillers of vegetable origin are used for the production of wood-cement compositions at the moment. Organic fillers along with the inherent valuable properties have a number of specific properties which have a significant effect on the processes of structure formation, structural-mechanical and construction properties of composites. The results of the research of the processes of water-soluble components removal from raw wood material are presented in the article. Processing of raw wood material was carried out in water and weak alkali solution in the research process. It is established that additional ultrasonic treatment considerably intensifies and increases the extraction of water-soluble sugars. The conducted research shows the possibility of improving the composite wood materials manufacturing technology with the aim of improving their performance without significant capital investments.

At present, technical regulations are adopted for furniture products of various types, establishing the protection of human health from the influence of harmful substances in the parts and assemblies of wood products and wood materials. The technical regulation adopted the requirements for ensuring chemical safety in the design and manufacture of furniture. The technical regulation is based on the condition of furniture products, eliminating the risk of harm to human health due to exceeding the maximum permissible concentration of harmful chemicals in indoor air. Such substances include free formaldehyde, migrating from the volume of chipboard and glue interlayers when gluing and veneering furniture parts and assemblies. Harmful chemicals are vapor-gas mixtures of solvents, the migration of which is observed from solid lacquer membrane of protective and decorative coatings of parts and components of furniture into the indoor air environment. These chemicals are present in the construction and auxiliary materials in the development of furniture. It is desirable that manufacturers of furniture products determine in advance, at the stage of its design, the level of safety when using certain raw materials. For this purpose, a technique is proposed that allows us to determine the concentration of harmful substances in the air of the premises with the selected materials, design and manufacturing technology of furniture products. Preliminary calculations based on the proposed method, allows us to determine the life of the furniture, in which the harmful substances migrating into the air environment of the premises will be within the permissible concentrations. This allows certifying the manufactured furniture products for chemical safety with the assignment of certain quality parameters. The proposed technique may be useful for enterprises focused on the production of furniture products.
