Abstract

Recycling of polymer materials is a very time-consuming and time-consuming process, and in the conditions of mixed waste collection, a complex situation arises that leads to the accumulation of substances that are dangerous to the environment. The world's experience in recycling polymer waste is not sufficient and does not allow to completely reduce the environmental burden on the environment. For the disposal of polymer waste, depending on the composition of incoming raw materials and the necessary characteristics for secondary products, processing and disposal methods are used (burial, mechanical crushing, thermal impact, chemical, etc.). to increase the share of solid household waste (SHW) for disposal with a shorter disposal period, there is a need for biodegradable materials from plant biopolymers instead of plastic. Today, technologies for obtaining biodegradable materials that are subject to recycling and recycling for various applications are being actively developed around the world. The purpose of this study was to study the processes (vapor permeability, water absorption and leaching of the filler) that occur in biodegradable polymers with different ratios of the main raw materials (corn starch (CS) and cellulose (C)). For the study, 4 samples of biodegradable material with the optimal specified component composition were prepared. In the course of our research, we found that sample 2 has the best barrier properties (CS:C in the ratio 1.5:0.5). The smallest leaching of the filler is observed in sample 3 (CS:C in the ratio 2.0:0.3). The results of the study showed that when changing the ratio of the main components in the matrix of a biopolymer material, the barrier properties of the material can be adjusted. The resulting biodegradable materials can be used as packaging materials.
