Abstract

It has been established that in order to streamline the use of forest resources in Ukraine it is necessary to accelerate the adoption of laws on resource conservation and the use of secondary waste. These laws should effectively target enterprises to the ecological and rational consumption of resources, and hence to the development and application of low-waste and non-waste technologies, resource-saving and reliable technology. To do this, the laws must provide for measures of economic responsibility for the irrational use of resources, and for the destruction of business waste - fines. PCW (Post-Consumer Wood) is an additional resource suitable for material use, in particular in the production of panel elements. It was investigated that the shape stability of the combined PCW-made blockboards and the combined PCW-made furniture panels with the use of rails in the width of 20-40 mm, meets the requirements of the standard. The shape stability of the combined PCW-made blockboards is higher than the the combined PCW-made furniture panels for identical structures, in particular the assembly elements - rails. It has been established that in order to provide enterprises with PCW, it is possible, in addition to ordinary panel elements, to make combined ones. It is recommended to use rails of small widths up to 40 mm to increase the shape stability of shield assembly units.
