Abstract
In the course of the activities of medical institutions, waste of various degrees of danger is generated, both for people and the environment. Collection and processing of such waste is currently carried out in accordance with SanPiN 2.1.3684-21. Elastomeric materials are mainly used as primary packaging material for the production of pharmaceutical closures. They are a complex multicomponent polymer elastic material, including an elastomeric component and various additives. In order to reduce the negative impact on the environment in terms of reducing the amount of medical polymer waste, a waste-free technology for processing used pharmaceutical plugs made of mixed thermoplastic elastomer, which belong to Class A waste, has been developed. According to SanPiN 2.1.3684-21, medical waste of class A is the only one that can be sent for recycling as recyclable materials without additional actions. They are safe because they did not interact with infectious patients and biological fluids, which means there are no toxic and radiation components. The starting raw materials for processing are pharmaceutical stoppers intended for sealing injectable forms of antibiotics, bacteriological and biological pharmaceuticals. The plugs are made of a medical-grade thermoplastic elastomer based on polyisobutylene and low-melting thermoplastic. The product has wear resistance, shock resistance, and elasticity at low temperatures. In addition, the material has good fluidity and is excellent for injection molding. The introduction of this technology will make it possible to recycle polymer medical packaging waste to obtain safe secondary material resources without having a negative impact on environmental components.
