Assessment of Healthcare Waste Management Paradigms and Its Suitable Treatment Alternative: A Case Study

Abstract EN

The management and treatment of healthcare waste (HCW) are of great concern owing to its potential hazard to human health and the environment, particularly in developing countries.

Nowadays, various technological alternatives are gaining momentum as efficient and favorable waste management options across the world.

However, selecting a suitable technology as well as an effective waste management approach for the treatment of HCW is still a challenging task for the municipal authorities.

This study renders a comprehensive analysis of healthcare waste management (HCWM) practices and the technological options for its better management through a case study in Khulna, the southwestern division of Bangladesh.

A number of healthcare establishments (HCEs) in the study area were selected and a questionnaire survey, as well as field investigations, was performed to find out the present status of HCWM and its limitations.

An assessment of different technological alternatives was also carried out using Sustainability Assessment of Technologies (SAT) methodology which could pave the way for treating hazardous waste more efficiently in the Khulna metropolitan area.

The study revealed that the overall HCW generation rate and hazardous HCW generation rate in Khulna city were 0.90 kg bed−1 day−1 and 0.18 kg bed−1 day−1, respectively.

Assessment of management system revealed that 56% (n=38) of workers did not receive any form of training in the handling of hazardous waste.

Around 54% (n=47) of them did not use any safety equipment or clothing.

It has been found from the study that, among different technological alternatives based on the final score, incineration was the most suitable option for the treatment of hazardous waste in Khulna.

Finally, some guidelines have been put forward to improve its existing management practices.
