5. Conclusion
This study is the first to apply a thorough, rational, and representative sampling plan to the estimation of medical waste generation in Dhaka. It is also the first to fully consider the contribution of nonresidential diagnostic centres, which were found to contribute a substantial proportion of waste. It is hoped that this estimate will be sufficiently reliable to allow sound planning. A review of the literature suggests that the remarkable relationships between the size of residential HCE and both the amount of hazardous waste per bed, and the proportion of hazardous waste produced, has not previously been observed. It, too, may have significance in planning.
