The creation of biodegradable polymer materials is one of the priority areas for the development of science. At present, quite a lot of waste of theAgro-Industrial Sector (AIS) has been accumulated in Russia, which is not reused, but disposed of by landfill. Most AIS wastes contain fiber, proteins and carbohydrates, which are natural components and serve as a breeding ground for microorganisms. Therefore, it is advisable to use AIS waste as a filler to create biodegradable polymers. Recently, increasing attention has been paid to the issues of physical modification of the polymers; which is based on the ultrasonic melts processing. It was established that the ultrasonic treatment of polymer melts leads to acceleration of oxidative processes, which is a positive criterion for the creation of biodegradable polymer compositions (BPC). The object of this study was the creation of biodegradable polymeric materials, which were obtained using ultrasonic treatment of the melts of the compositions. The objects of study wereAIS waste (husk: buckwheat, sunflower, millet, rice,cocoa bean shell and beet pulp) and corn starch, polycaprolactone. The compositions were obtained on a laboratory extruder with ultrasonic treatment of their melt. The following studies were carried out during the work: weight change of the polymer sample in contact with water; the rheological properties of the obtained polymers were determined; the stress-strain characteristics of the obtained polymer compositions were determined; composting method. After the analysis of the group of fillers, the following wastes - beet pulp, cocoa bean shell, rice husk were selected to create biodegradable polymeric materials. As a result of the research, it can be noted that the polymer compositions containing fillers based on AIS wastehave an accelerated biodegradation period, which today is an important aspect of many areas of the research in the field of creating polymer materials with controlled durability and the intensification of biodegradation processes of packaging materials, especially having a one-time use. The research was supported by the Ministry of Education and Science of the Russian Federation, the uniqueidentifier of the project is RFMEFI57418X0191.
