Manufacture of shoe insoles by environmental treatment of cattle skin

This research work is aimed at considering the scientific and practical foundations of the use of cattle skins for shoe insoles through environmentally friendly processing methods. Currently, one of the most pressing problems is the negative impact of traditional chrome tanning technology on the environment and human health. The purpose of the research work is to identify effective ways of processing cattle skin by environmentally safe methods and to study the possibilities of using the resulting leather for shoe insoles. In the course of the study, the main directions of bioprocessing, that is, enzymatic processing, tanning using microorganisms, plant-based Kneaders and chromium-free technologies were considered. The environmental, technological and qualitative advantages of each method were compared with traditional methods and a comprehensive analysis was carried out. The scientific novelty of the study is aimed at summarizing environmental methods of skin treatment and demonstrating on a scientific basis the possibilities of their application in the production of insoles. In the methodological context of the research work, methods of comparative analysis, ethical review, structural systematization were used. This study paves the way for the introduction of new approaches to leather production aimed at protecting the environment. Using the presented technologies in domestic production, it is possible to prepare high-quality, safe and durable shoe insoles. The results of the study contribute to the areas of leather processing and light industry.
