Survey of Solid Waste Situation in the Specialist Hospital in Tehran with ‎Emphasize on Quantity of Waste Production

Introduction. Solid waste is one of the important environmental pollution. With improvement ‎of technology and increase of population, production of Solid waste is more and more diverse. ‎The resultant special attention to solid waste management (SWM) is very important. Now day ‎methods of SWM that were conducted in hospitals of IRAN, in some cases aren't correct and ‎complete, and needs to optimize. The aim of this study was to survey quantity of solid waste ‎production in hospital (that is specialist and one of the largest hospitals in Tehran with 682 beds) ‎for determination of present situation and Comparison results with others.‎ Material and Methods. This is a description cross sectional study, about quantity of solid ‎waste production in one specialist hospital. We weighted infection and general waste production ‎during 85 days in days of week Saturday - Friday in at 23-24 o'clock of night before transported ‎to out of hospital by shahrdary. The data obtained were analyzed statistically using by SPSS ‎software and ANOVA and Tukey test.‎ Results. The results showed that the mean weight of general waste production had a significant ‎difference between Friday and others days of week (p < .05). -Mean density of general and ‎infection waste was 101.15 and 94.63 kg/m3. Mean weight of general and infection waste 1297.6 ‎and 640.86 kg/day and mean bedridden was 431 disease /day. Mean weight of general and ‎infection waste production per diseased per day were 3.07 and 1.52 and total 4.58 kg/diseased. ‎The cost of only disposal solid waste production from hospital per diseased per day was 2131 ‎rials. From Total solid waste production, general and infection waste was %67 and %33.‎ Discussion. In survey of SWM in hospital, determination the present situation, quantity and ‎mean solid waste production per diseased or beds per day is very important and we attended that ‎during this study. Production of total solid waste was 4.58 kg/day and in comparison with ‎quantity of expected in IRAN (2.71 kg) and %33 from total waste production was infection ‎waste and in comparison with quantity of expected in WHO for developing country (%10-%15) ‎are very high, because the separation of general and infection waste wasn’t complete conducted. ‎The result from this study show that stages of SWM in hospitals of IRAN to have need ‎optimization and more attention through support by managers in hospitals and government. ‎
