Generally, hospital wastes are highly harmful and infectious in nature. Management of hospital waste is a crucial need for most of the cities in the world. In Khulna city of Bangladesh hospital waste management (HWM) system had been focused on collection and dumping only. The present improper management of hospital waste in Khulna city may play a vital role for contamination of nearby communities and spread the occurrence of skin diseases, asthma, diarrhea, allergy, eye irritation, etc. The aim of this study was to investigate the existing HWM system and determine the hospital generation rate according to different categories in Khulna city. The study was carried out in six hospitals that produce major portion of medical waste in the city. For this reason, a questionnaire survey was conducted to observe the existing management system, generation rate and type from the hospital authority. Field survey was conducted to categorize and measure the generated waste by weight machine directly to compare with the data from questionnaire survey. The study revealed that the average generation rate of different categories of hospital waste such as general waste, anatomic waste, pathological waste, chemical waste, pharmaceutical waste, infectious waste, sharp waste and liquid waste were 0.138, 0.0028, 0.0091, 0.0036, 0.0009, 0.0334, 0.036 and 0.0205 kg/day/bed, respectively. The study showed that there was no radioactive waste in the selected hospitals of Khulna. Improper segregation, lack of treatment, consciousness and financial support are liable for inappropriate management. Finally, a management system was proposed including proper segregation and storage by selected colored container, proper collection, safe transportation, proper treatment and disposal for improving existing system. Regular monitoring and assessment of hospital waste by hospital and city authority will also be needed for a safe and healthy environment.
