Evaluation of the Effectiveness of Separate Collection of PET Bottles Using Street Container-Baskets.

The efficiency of separate waste collection using street container-baskets for used bottles of polyethylene terephthalate (PET bottles) has been evaluated. The proportion of foreign objects in the flow of plastic bottles was determined and the composition of components mistakenly placed in the container was analyzed, which allows us to judge how the population relates to such systems and how effective the outreach is. The target stream of PET bottles was sorted by volume and color. The results obtained make it possible to evaluate the most popular type of PET bottles by size and color, which can be used to assess the possibilities of improving the collection system and technologies for further processing the resulting stream of PET bottles.
