Analysis of the sustainability of reusing industrial wastes as energy source in he industrial sector of Taiwan

The objective of this paper was to provide a preliminary analysis of energy utilization from industrial waste in Taiwan, a densely populated island country with high dependence on imported energy. The discussion thus focused on the status of industrial waste generation and its management since the year 2002. This paper also presented the updated information about the new/revised regulations concerning the governmental regulations and policies for promoting industrial waste as energy source as well as controlling the emissions of hazardous air pollutants from industrial waste-to-energy facilities. It showed that the main types of combustible waste in the industrial sector of Taiwan include pulp sludge, scrap wood, sugarcane bagasse, textile sludge and scrap plastics, which were being reused as auxiliary fuel in the utilities (e.g., boiler and incinerator). Based on their reported quantities, the energy potential and the environmental benefit of mitigating CO2 emissions were also analyzed in the study. (C) 2010 Elsevier Ltd. All rights reserved.
