Health Care Waste production: measures and estimates in “V. Cervello” Hospital, Palermo, Italy.

Abstract

A monitoring work was carried out in May/June 2007 in one large hospital located in Palermo. The monitoring consisted in weighing the infectious waste containers filled in some Departments purposely chosen. As a second stage of the work a comparison was attempted between the results obtained from the waste production monitoring and the Hospital’s purchases recorded in the same time. A restricted list of purchased products out of the general one was extracted. Such list allows one to calculate approximately the mass of medical devices purchased and their composition. To these materials a reasonable change in humidity after use was attributed. It was possible in this deductive way to draw a probable amount and composition of waste materials really arising from health care activities (commonly – though not rigorously – considered all infectious), whose characters is forbidden to ascertain by direct inspection.
