The article discusses the creation of new polymer-starch compositions based on starch extracted from nongraded wheat grains, hydrolyzed sugar beet pulp and polyethylene glycol. The main points of agricultural waste disposal are discussed with the aim of obtaining products with new properties, safe for the environment and biodegradable. Prototypes have a uniform distribution of particles in the matrix, provide enough tensile strength and elongation under tension. A study on the selection of the mass ratio of the components revealed the optimal concentration of the components. The temperature of exposure to the composition to obtain biodegradable material is 105 ° C. It was shown that the tensile strength of samples of the polymer composition decreases with an increase in the rotational speed of the screw to 150 min-1 and a temperature above 1300C. Speed below 110 min-1 lead to an increase in strength. The obtained experimental material opens prospects for further research with respect to improving the properties of these biocomposites based on starch and sugar beet pulp by modifying starch and searching for compositions with starch, using reinforcements (both organic and inorganic) and processing conditions.
