Abstract: Skril Y.A.; Yaremkevych O.S. (supervisor). “Investigation of biodegradable films based on starch”. Master’s thesis - Lviv Polytechnic National University. Lviv, 2024. Extended abstract Object of research - biodegradable films based on starch Research area - biodegradable materials and environmental biotechnology The purpose of the research is to isolate enrichment cultures from the soil, potentially capable of decomposing biodegradable films made in the laboratory in comparison with industrial samples. Also, to conduct initial identification of microorganisms by microscopy of permanent mounts, as well as experimental determination of the ability of microorganisms to biodegrade BP based on strarch and studies of its physicochemical properties in the process of biodegradation. Bioplastics derived from renewable biomass are widely used in the market due to their environmental friendliness, natural bioconversion, sustainability, and economic benefits. In addition, the bioconversion products of starch biopolymers in the soil can serve as substrates for various microorganisms. Therefore, research and improvement of technologies for the production and processing of starch-based biopolymer materials using plasticizers are extremely important. In the main part, we studied the isolation of accumulative cultures from the soil, potentially capable of decomposing biodegradable films made in the laboratory in comparison with industrial samples. In the calculation part, the material balance of all stages of biodegradable films production was performed. Also, a basic technological flowchart for the production of biodegradable films was developed and designed. In the economic part of the work, technical and economic indicators were calculated and the economic feasibility of this work was proved. The conclusions formulated in the work are in accordance with the literature and are based on experimental material using modern physical and chemical research methods).
