ANALYSIS OF EXISTING WASTE TREATMENT TECHNOLOGIES
Over the past decades, the morphological composition of waste has undergone very significant changes. If earlier up to 70% of waste was food waste, textiles, paper, wood, and only 30% of waste was polymers, today the situation is completely reversed meaning up to 70% of waste is polymers. The period of their natural decomposition is tens and hundreds of years. Experts predict that by 2030 about 90% of waste will be made up of polymers, plastics, multi-layer tetra pack packages, and inner linings of cars as well as aircraft, to name but a few. On the other hand, burning these waste materials will provide more negative and toxic effects on the environment. The overwhelming majority of technologies used for waste disposal, from the point of view of ecological safety, already do not comply with regulatory requirements. Consumption of various products and raw materials is growing all over the world, the dynamics of waste growth is increasing and effective and modern technologies for waste disposal are critically small.
The application of this technology does not lead to an increase in the cost of equipment for waste disposal
The main methods of waste disposal today are incineration by waste incineration plants. The process is conducted by blast furnaces and cement furnaces as well as separation being followed by burial of residues at landfills. Incineration of 1 ton of waste results in the formation of 3500 m3 of flue gases containing soot and a number of highly toxic substances—furans, dioxins, naphthalene, nitrogenous compounds to name but a few. This requires the use of expensive treatment technologies, which are (constructively) 60 to 65% efficient, entailing significant pollution of the environment being followed by clear consequences for human health. The huge increase in the number of cancers, chronologically, coincides with the beginning of the use of waste incineration technologies as an industrial method of waste disposal since the beginning of the 70s of the last century. From the point of view of the possibilities of industrial application as well as environmental parameters, at the present stage, the most effective method of waste disposal is the technology of electric arc plasma gasification.
The gasification occurs by the application of air plasma obtained by a high-voltage interelectrode discharge with the decomposition of the waste material into elementary components under the action of high temperatures. The process of gasification of waste is conducted with the production of synthesis gas, as the main product of recycling. The main disadvantages of the method are the high price of electrodes and their short service life – up to 400 hours on average. Besides, the method of low-temperature pyrolysis is widely used for waste disposal, which is characterized by low operating costs and good environmental characteristics.
The main disadvantage of this method is that the obtained recycling products – pyrooil and pyrocarbon – are not final products and require further processing for their commercial use. The most promising way of waste disposal, in the near future, will be the combination of several methods in a single technological cycle including separation + pyrolysis + plasma gasification. Separation is the extraction of recyclable materials from waste. Pyrolysis is the economical production of solid and liquid carbon-containing materials from waste. Plasma gasification is the recycling of all residues and intermediate products of waste processing into synthesis gas.

Absence of combustion (oxidation) in the waste disposal cycle
The application of this technology does not lead to an increase in the cost of equipment for waste disposal
