“…The basic reaction is oxi-chlorination of products of incomplete combustion, such as soot, catalysed by copper compounds, in a temperature range above 200°C (Stieglitz and Vogg, 1987;Hagenmaier et al, 1987;Hiraoka et al, 1987).…”

“…For the sake of safety, inorganic sorbents such as zeolites were used for monitoring and inertisation of CO [54]. It was also found in the 1980s that oxidative catalysts have high degradation potential for dioxins [55]. Those catalysts were initially operational at 300 to 350°C, and then they were further developed to reach higher destruction efficiency of 99% at temperatures of about 230°C [56].…”

PCDD/Fs are a 75-member family of toxic chemicals that include congeners (members) that have serious health effects including congeners that are classified group 1 carcinogens, endocrine disruptors and weakening or damage to the immune system. Municipal solid waste (MSW) incinerations had historically been implicated as the major source of PCDD/Fs distributed by air. As a result of awareness and legislation most European MSW incinerators were either shut down or equipped with modern air pollution control systems necessary to achieve MSW incineration with PCDD/F emissions within regulatory limits set by national and international laws (typically <0.1 ng TEQ/Nm3). There is a common belief that gasification of waste and/or biomass, unlike incineration, inherently and always achieve emission below regulatory and detectable limits. However, a review of the literature suggests that the belief that the substitution of incineration with gasification would always, or necessarily, reduce PCDD/Fs emissions to acceptable levels is overly simplistic. This chapter discusses the mechanisms of PCDD/Fs formation, the operational measures and parameter ranges that can be controlled during gasification to minimize PCDD/Fs formation, and methods for post-formation PCDD/F removal are reviewed. The purpose of this chapter is to assist researchers and practitioners in formulating waste management policies and strategies, and in conducting relevant research and environmental impact studies.

“…The study showed stable behavior of PBDDs and PBDFs obtained from combusting PBDPEs contained in PUF at combustion temperatures ranging from 64 0-760°C. Moreover, typical combustion temperatures in a MWC can vary widely (Benefenati et al, 1983;Hiraoka et al, 1987;Ozvacic et al, 1985;Tiernan et al, 1983). Minimal combustion temperatures have been reported to range from 320-1010°C.…”
