Healthcare is an important sector that serves the Malaysian population and is in high demand. The sector's carbon footprint has an impact on the natural environment, and healthcare waste management services reduce this environmental impact. This study examines residents' knowledge, perception, and willingness to pay for healthcare waste management services. A total of 384 respondents, selected through the cluster sampling method, participated in the survey for this study. The research sample comprised Putrajaya residents who were at least 18 years old. The findings showed that the respondents had a broader knowledge age. The respondents also had a slightly high perception of environmental issues. The estimated willingness to pay values were RM6.73, RM5.90 and RM5.32 annually for those in the bottom 40%, middle 40% and top 20% income groups, respectively, based on the results of the double-bounded contingent valuation method. The annual willingness to pay value was approximately RM2.34 million (US$0.54 million). The residents mostly preferred to pay annually via online banking. These findings could help decision-makers attain residents' support by identifying the affordable amount for the fee and the preferred payment methods. It will also help determine how to best collect healthcare waste management service fees and develop new healthcare waste management policies.
