Abstract
Waste from the leather and footwear industries is not disposed of at the enterprises, but is taken to landfills, which leads to environmental pollution. Research of waste processing technology in order to reduce their negative impact on the environment is an urgent task. The paper considers the processes of shredding leather and Shoe production waste, technological processes for obtaining secondary raw materials and products from them. For this purpose, an installation has been developed that allows studying the process of grinding waste suitable for further processing in laboratory conditions. Studies were carried out to determine the rational modes of the technological process of grinding waste from these industries. The sequence of processing and the obtained values of the modes are recommended for use in production conditions.
