Paints and varnishes (further-LKM) are chemical products which contain substances harmful to the person in the structure. It is these harmful substances that can affect the human body through the respiratory tract, skin and digestive tract. There are several basic methods of utilization of coatings used by LLC "Ecouniversal". Each of them has its own characteristics and rules: 1) Burning in special furnaces. Prior to the disposal of this type it is necessary to make a preliminary study of coatings. Selection of a suitable temperature regime is carried out and the possibility of full utilization is evaluated. Some representatives of coatings, having the properties of stickiness and viscosity, can not be completely disposed of by burning in special installations. 2) the Method of recovery. This method is most often used for the disposal of solvents. The method is based on the phenomenon of adsorption — an increase in the concentration of one substance on the surface of another. Active carbon and silica gel act as an adsorbent. Equipment for recovery is quite compact, and the use of carbon fabric makes the work of adsorbers continuous. 3) Plasma destruction. The whole process is carried out in a plasma reactor. The unit consists of two reaction chambers and special baths. Molten metal takes part in the process of waste disposal. On its surface fall waste. The residual gas enters the gas cleaning system. The main advantage of this method is the possibility of using the obtained gas as an alternative fuel. 4) a Method of disposal. Disposal of paint and varnish waste takes place only in a specially equipped area. At the same time there is no air pollution. The drawback-the need for permission of regional authorities. The likely re-entry of wastes. 5) waste Recovery. Regeneration of coatings consists of several stages. The first stage is the partial dissolution of the waste in the mixer together with the solvent and filtration of the resulting mixture through a strainer to separate large particles. The second stage is feeding the mixture into a ball mill for dispersion and subsequent filtration through a mesh with smaller cells. The process is repeated until the required dispersion is reached. After achieving the desired result, the solvent is poured into the mixture to obtain the necessary consistency. The final stage is the packaging of the paint. Paint that contains oil may not be disposed of in this way. It should be noted that according to Annex 2 of SanPiN "Hygienic requirements for the placement and disposal of production and consumption waste", some types of paint and varnish waste are not allowed to be placed on solid waste landfills. These wastes include: - Films of varnishes and enamels, waste at cleaning of the equipment containing zinc, chrome, solvents, oxidizing oils; - Slimes containing zinc, magnesium. For such types of waste it is necessary to apply alternative methods of utilization of LKM. Specialists of LLC Ekouniversal have high qualification in the field of the address with these types of waste. The works are carried out in accordance with the current environmental legislation, on the basis of current permits and licenses.
