The method of recycling of hydrogen fluoride production wastes – acid fluoride – by processing it into environmentally safe building materials – acid fluoride finishing panels (PANO) is proposed. A continuous laboratory unit designed to produce PANO sheets from neutralised acid fluoride has been developed and tested. The detailed technological scheme of the whole process is presented, including preparation of raw materials, moulding of products in the given geometrical parameters, as well as their subsequent ageing until the required performance characteristics are achieved. The main constructive solutions of the unit are described, due to which the uniform distribution of the initial mixture is achieved. It is concluded that the proposed technology contributes not only to the expansion of the resource base of the construction industry due to the secondary use of technogenic raw materials, but also to a significant reduction in the overall ecological load on the environment.

The effect of sonoplasma discharge on the bacterial-fungal complex of microorganisms during the treatment of irrigation water from a greenhouse was studied. New data have been obtained on the resistance to sonoplasmic treatment of species of microorganisms typical of greenhouse wastewater, including those that pose a danger to plant pathogenesis. It is concluded that The sonoplasma discharge treatment of greenhouse irrigation waters is more effective in eliminating bacteria than mold fungi. It is shown that the inhibitory effect on the propagules of microscopic fungi is directly proportional to the frequency of treatment.
