Abstract
Alexandria, which was one of the cleanest cities all around the wofld, is severely suffering from the problems of solid wastes. Among the most hazar.dous wastes arising in any community are the health care wastes. As their amounts increase, the need of a management system for their handling and disposal also increases. l1o~pital wastes are classified. by the WI10 into pathological, infectious, chemical, pharmaceutical, radioactive and domestic wastes in addition to sharps and pressurized containers. The risks caused by hospital waste mismanagement could be either health hazards within the hospital or environmental risks to the community. Generally, the management of hospital wastes involves the determination of waste generation, the waste handling (Le. segregation, packaging, labeling, marking, storage and transport), and waste treatment for final disposal. The present study aimed to determine the quantities of wastes generated by hospitals, to analyze these wastes physically and chemically, to overview the incineration as a treatment technique and to recommend a management plan for hospital wastes in Alexandria. To attain these goals, 16 hospitals were selected randomly from the 6 Alexandria districts according to the proportional allocation method of sampling. In each hospital, the daily output of wastes was weighed and the average of 4 successive days was calculated. Then the unit generation rates in terms of Kg/bed/day and kg/patient/day were also determined. In addition, wastes were spread over a vinyl sheet and were analyzed physically. The weight percentages of different waste components (plastic, paper, textile, food, rubber, metal. and glass) were determined. At the same time, the different waste categories (according to the WHO classification) were also determined in terms of weight percentage. Chemical analysis of all components were done in the Institute laboratory for purpose of determining the moIsture, ash and combustible contents of wastes as well as their calorific values. Information about the waste management systems applied in the surveyed hospitals were collected by means of a questionnaire. The study revealed the following results: lIospital waste generation rate was about 0.82 kg/bed/day which was relevant to 1.47 kg/patient/day. These wastes were consisting of 28.65 food residues, 24.72 paper, 18.20 textile, 12.48 glass, 12.11 plastic, 1.93 metal and 1.92 rubber.
