Development of technology of molded biodegradable eco-tableware based on secondary resources of grain production

Today, the issue of reducing the accumulation of solid municipal waste, in which plastic products prevail in significant volumes, and the disposal of polymer waste is relevant. One of the effective ways to solve this issue is the development of biodegradable materials of different organic composition. Scientists all over the world are conducting scientific research to obtain organic biodegradable materials, which in their functional properties can be close to polymers, but at the same time decompose in a short period of time under normal conditions with the accumulation of simple organic substances, which means they are safe for the environment. The purpose of this study was to develop a technology (technological features) and a recipe for obtaining a molded biodegradable material for the production of eco-friendly tableware. Within the framework of this study, molded products were obtained from a mixture of biodegradable materials (wheat bran and a biopolymer component), which were investigated for their structural and mechanical characteristics. For the study, six samples of rectangular plates with different ratios of the main raw material (wheat bran) and an organic biopolymer composite based on modified starch were molded as a prototype, taking into account technological features (force, exposure and temperature). In the course of the study, we found that with an increase in the content of the biopolymer component in a mixture with the main raw material, an increase in the strength properties of products is observed. The developed recipe and technology can be used to create eco-friendly tableware of various designs to reduce the impact on the environment.
