To develop suitable infectious industrial waste management strategies, characterizing the volumes and composition of infectious industrial waste is important. The quantity of infectious industrial waste produced depends upon several factors such as size of healthcare facilities, the separation program for infectious industrial waste, and infectious industrial waste activities. In Taiwan, the EPA and Department of Health have assessed the quantity of infectious industrial waste.
Since 1988, the Department of Health has evaluated the production of infectious industrial waste using questionnaires and telephone interviews; assessment results were grouped by hospitals and clinics. The adopted evaluation factors were 3.5 kg of waste for each bed per day in the hospital setting (occupation rate, 80%) and 3.5 kg of waste per day in the clinic setting. The amount of infectious industrial waste generated was assumed to be 20% of total medical waste. In 2000, the EPA estimated the amount of infectious industrial waste generated based on questionnaires. Assessment results for hospitals were total medical waste = number of beds × 3.4 (kg/bed/day) × occupation rate. The occupation rate was assumed to be 60% and infectious industrial waste was assumed to be 15% of total medical waste. Infectious industrial waste = total medical waste × 15%. In southern Brazil, the average rates for total waste and infectious-biological waste generated by hospitals was estimated at 3.25 and 0.57 kg/bed-day, respectively (Da silva et al., 2005). In Korea, the estimated rate for medical waste generation from general hospitals was 0.48 kg/bed-day, assuming a bed-occupancy rate of 100% (Jang et al., 2006). The generation rate estimated in Taiwan was comparable to those identified by other studies ([Pruss et al., 1999] and [Da silva et al., 2005]).
