Pre-Treatment of Vegetable Waste in the Production of Composite Materials Ruslan R.
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.
The currently produced wood-mineral composite materials are widely used in the construction, but have several drawbacks.
