Prospects for the Recycling of Disposable Packaging Waste

Abstract

Introduction. The problem of using disposable packaging waste that has lost its original properties and is not yet obsolete is very acute and urgent, it has economic and environmental aspects. Purpose. The purpose of the work is to assess the prospects for recycling various types of disposable packaging. Materials and Methods. An analytical review of the current state of various aspects of recycling of disposable packaging waste has been carried out. The determination of the physico-mechanical properties of the compositions was carried out in accordance with GOST 14236-81 "Polymer films. Methods of tensile testing". To determine the molecular weight of polymers, a viskosimetric method was used. Experiments were carried out for PE and PP in o-xylene at a temperature of 85 ± 3 ° C, PA in m-cresol at a temperature of 25 ± 3 ° C. For PET, the molecular weight was determined in the chloroform and acetone system at a temperature of 25 ± 3 ° C. Results. It is shown that the recycling potential of secondary material resources depends not only on the technologies to which the article is devoted, but also on the quality of incoming raw materials, its uniformity, the degree of contamination with various materials and organic compounds. Conclusions. The results obtained make it possible to significantly increase the volume of recycling of disposable packaging waste.
