Considerations in Recycling Research: Laboratory Practices for Fibrous and Plastic Materials at Russian and Uzbekistan Universities

As the demand for sustainable recycling of fibrous and polymeric waste increases, university laboratories play a crucial role in developing new technologies while training future professionals. This study presents a practical model for conducting safe, student-led laboratory research on the chemical recycling of textile waste with a focus on silk and cotton materials. It outlines safety measures for managing chemical and biological hazards including waste classification, disinfection protocols, and risk assessment procedures adapted for educational settings. Key innovations include the use of express tests for verifying bacterial decontamination, tailored workspace organization, and the application of solvent-based cleaning for material purity, a general approach to laboratory management that emphasizes student and staff responsibilities to health and safety. The study also reviews regulatory compliance and engineering controls specific to Russian and Uzbekistan academic settings. The proposed approach, supported by case studies, demonstrates the safe engagement of students in meaningful recycling research while mitigating risks associated with fibrous waste handling and chemical processing under the guidance of staff members who are not specialist health and safety professionals.
