[Disposal of waste glass in sanitary departments: a sample survey in the Lazio region].
As a result of Italian law, DPR 15/7/2003 n. 254, about hospital waste, and given that little has been written about recycling waste glass in hospitals, a survey of 28 health departments in Lazio was performed. The objectives were: to estimate the mean quantity of clear vitreous waste in one year, to estimate how vitreous waste is administered, to estimate the extent of the use of plastic instead of glass, to analyse the costs and benefits of glass use and/or plastic use and to evaluate staff training about hospital waste disposal. The average production of clear vitreous waste was 0.28 kilogram per day per hospital bed occupied. (This would be the theoretical maximum quantity of glass to be recycled). Among the 28 departments studied, 82% separated waste products but only 36% disposed of glass in accordance with the law. The estimated possible savings on glass phleboclysis in 2002 year were 35,000 euro. Staff training could avoid this conspicuous waste of money. Fifteen departments also used plastic phleboclysis; of these, in 2 departments plastic waste is separated in the wards, but unfortunately this material is later disposed of in the bins for general solid urban waste. The other thirteen hospitals dispose of waste plastic as infectious material. Using glass phleboclysis instead of plastic phleboclysis would save about 680,000 euros per year. The disposal of glass waste material in practice was not found to follow the principles taught in the training courses. Theoretic data about glass production, estimated in this survey, refers only to clear glass and it is an underestimate of that of all glass used in departments. The quantity of glass actually recycled has been about 0.14 kilogram per day per hospital bed occupied and thus only 50% of the theoretical quantity (0.28 kilogram per day per hospital bed occupied). This percentage could be improved by effective training. Ideally, the disposal of waste glass would follow the legal requirements and be monitored locally.
