Materials and technologies for manufacturing of products based on polyurethane waste

The article presents technologies for recycling polyurethane foam waste. Various prescription formulations for obtaining materials for various purposes are presented. The latest directions of work in this direction are described. The scientific novelty of the work is presented by the development of new materials using PPU waste with a sufficient level of physical, mechanical and operational properties for the production of shoe soles. The practical value of the work consists of obtaining materials with a certain set of properties that meet the requirements of regulatory documents and are within the framework of traditionally used materials for the shoe bottom.
