METHOD FOR COMPLEX TREATMENT OF MEDICAL WASTE Russian patent published in 2022 - IPC A61L11/00 B09B3/00 

FIELD: medical equipment.

SUBSTANCE: claimed invention relates to medical equipment, namely to a method for complex treatment with medical waste. The method includes separation of all waste at places of their formation in each medical organization, depending on a waste grade, into four streams: a stream of grade A waste, a stream of grades B, C waste, excluding organic and pathoanatomical waste, a stream of grades B, C waste: organic and pathoanatomical waste, and a stream of grade D waste, and transportation to a centralized station for treatment of medical waste in a region. Then, streams of grades B and C, excluding organic and pathoanatomical waste, are disinfected by a low-temperature hardware method, namely are disinfected with water saturated steam under excessive pressure. Then, streams of grades A, B, C, and D, excluding organic and pathoanatomical waste, are sorted on a conveyor to form new waste streams, depending on their morphological composition. New waste streams include streams of grade A waste, including paper, polymer, glass, and metal waste, as well as streams of grades B and C waste, including polymer, laboratory, glass, metal waste, which are disinfected with mechanical destruction by pressing or shredding, eliminating their reuse, and then are processed into secondary raw materials. New waste streams include streams of other grade A waste, other grades B and C waste, excluding organic and pathoanatomical waste, grades B and C waste: organic and pathoanatomical waste are disinfected by a thermal method – combustion of waste in an incinerator or thermal decomposition of waste in a pyrolysis installation, next, ash is disposed at a landfill. New waste streams include a stream of grade D waste: X-ray, mercury-containing, pharmaceutical, which are disinfected by a method corresponding to each type of waste, and then are disposed at the landfill.

EFFECT: creation of an economically effective complex method for treatment of medical waste of A, B, C, and D grades, providing secondary processing of utilized materials and reducing negative impact of waste on the environment.
