“…(3) Energy recovery (i.e., CHP) unit refers to the simultaneous production of electricity and heat in one single process for dual output streams so as to maximize its thermal efficiency of up to 70% or more. The flue gas from the CHP system will be further treated by the advanced air pollution control systems for removing chlorinated pollutants, heavy metals, acidic gases (e.g., nitrogen oxides) and particles [4,18].…”

“…In early 1990s, the central competent authority Taiwan adopted a strategy promoting the treatment of MSW incineration [4]. The energy utilization from MSW and various other types of agricultural and industrial waste, also called waste-to-energy (WTE), received much attention during the 1990s mainly due to the advances in WTE technologies, the increasing energy price and the global warming issues [5,6].…”

“…The energy utilization from MSW and various other types of agricultural and industrial waste, also called waste-to-energy (WTE), received much attention during the 1990s mainly due to the advances in WTE technologies, the increasing energy price and the global warming issues [5,6]. More importantly, the energy from domestic waste resources not only enhances fuel diversification, but also possesses environmental benefits in terms of greenhouse gas (GHG) emissions, land use and cost savings as compared with land-filling [4]. In this regard, biomass such as agricultural residues and biosolids are increasingly being recognized as valuable bioresources because they are renewable and rich carbon sources.…”

“…In a previous paper [4], only a comprehensive description of governmental regulations and policies for promoting industrial waste (i.e., pulp sludge, scrap wood, sugarcane bagasse, textile sludge, and scrap plastics) as energy sources was presented. Environmental regulations on the emissions of hazardous air pollutants as well as benefit analysis from industrial waste-to-energy (IWTE) were also discussed.…”

Abstract:The objective of this paper was to provide a preliminary analysis of energy utilization from biological wastewater treatment sludge (biosludge) in Taiwan, a densely populated country (estimate 640 persons/km 2 ) with a high dependence (over 99%) on imported energy. The discussion focused on the status of biosludge generation and its management in the years [2004][2005][2006][2007][2008][2009][2010]. Findings showed that the main types of combustible waste (i.e., biosludge) produced by the industrial and agricultural sectors of Taiwan included food processing sludge, wine brewery sludge and agricultural sludge which may be reused as auxiliary fuel in the utilities (e.g., generator, boiler and incinerator). Furthermore, two conceptual biosludge-to-energy systems have been addressed with regard to the thermochemical conversion processes. One is to adopt direct combustion for power generation in the combined heat and power system. Another system uses pyrolysis and gasification for producing biochar (solid fuel), bio-oil (liquid fuel) and syngas (gas fuel). Based on their thermochemical properties and reported generation quantities, the energy potential and the environmental benefits of mitigating CO 2 emissions were also analyzed in the study, showing around 1.1 × 10 3 TJ/year and 57 Gg CO 2 /year, respectively.

Heavy metals in combustible materials such as fossil fuels, biomass, municipal and medical wastes, sewage sludges, and in industrial wastes such as slags, are important pollutants for the environment. The bottom ashes and fly ashes from the combustion and incineration processes contain heavy metals as enrichment products in significant ratios. Therefore, heavy‐metal enrichment after combustion and incineration processes have been extensively discussed in this chapter. The health effects of heavy metals are described, with special attention paid to safe use of the combustion and incineration residues and fly ashes. The utilization of residues and fly ashes in cement production, soil remediation, adsorption of different pollutants and heavy metal recovery are outlined, as well as the stabilization/solidification of ashes and slags.
