In many countries in the world waste segregation has already been introduced at the beginning of the recycling path, i.e. at home. Just people divide waste into groups such as plastic, metal, glass and organic/bio. The use of selectively automated techniques for these groups is easier than for municipal solid waste (MSW). Unfortunately, a large part of the waste is still collected in the form of the MSW, which is why the countries strive for the most effective reprocessing of waste materials. In order to do this, you should effectively sort the rubbish into individual factions and materials. Therefore, an important task is to isolate individual types of materials from the MSW. Therefore, techniques and procedures for segregating waste are used for the main groups of materials such as paper, glass, metal, wood, plastic and biomass by property system. The biggest challenge, however, is the separation of various types of materials within a given group, i.e. sorting different colour of glass or different types of plastic. The problem of plastic garbage is interesting and at the same time important due to the possibility of recycling only some types of plastic (e.g. PET).
