Comparative Techno-Economic Study of Incinerators and Thermal Power Plants for Disposal of Hospital Waste
Abstract
The article is a feasibility study to produce thermoelectric power by incineration of hospital infectious waste and search for the viability of substitution of currently functional incinerators with electric power plants. The secondary data was collected from the published and Internet. Primary data were collected from Children Hospital and Pattoki Sugar Mills. The data after collection were computed and then applied to design different projects appraised to determine the Benefit to Cost Ratio (BCR), Net Present Value (NPV) and Payback Period (PBP). The results showed that Children Hospital, Lahore currently produces approximately about 211.7 tons of infectious waste per annum that undergoes incineration. The electricity that can be produced with this amount of waste is 296,400 kWh / annum. The appraisal of the project excluding even land price showed BCR of 0.5 which is less than 1, NPV is -Rs28, 141,619 (below zero)and the payback period 4.3 years making the project non-feasible. However, after taking into account the incineration of infectious waste of three other local hospitals with Children Hospital making 730 ton/annum the project becomes feasible as BCR is equal to 2, NPV is equal to Rs. 74,403,879 and PBP is 1.2 years, if price of land is excluded.
