Abstract

The problem of disposal of municipal solid waste (MSW) is considered, taking into account the presence of inclusions in them in the form of paint and varnish coatings of printing design. It is shown that their disposal, given that more than 90 % of MSW have such inclusions, requires sound technological solutions. It is shown that the main problem is the disposal of “mixed waste”, which covers all plastic packaging waste from household waste and includes rigid and flexible products from various types of polymers and colors, which are usually created with a print design element. It is proposed to use high-temperature disposal methods based on pyrolysis and gasification processes. It is advisable to consider such methods in combination with technologies for obtaining alternative energy carriers and obtaining various types of substances and energy on their basis, for example, mechanical, thermal and electrical. A description of the processes of gasification of low-grade solid fuels by the method of thermodynamic modeling is presented. It is shown that the economic efficiency of waste disposal increases significantly when the pyrolysis and gasification processes are combined when the pyrolysis plant and the gas generator waste disposal process are combined into one technological process, which will make it possible to bring the waste utilization to almost 100%. It is also indicated, as promising, the use of gasification and pyrolysis products, including coke and hot ash, in external combustion engines of the Stirling engine type (with external heat supply).
