GUIDELINES ON BAT AND GUIDANCE ON BEP DRAFT 29/07/04 Table 6-1: European Union BREF Reports on Best Available Techniques Determinations, continued Waste incineration – BREF Report European Commission IPPC Reference Document on Best Available Techniques for Waste Incineration, Draft May 2003 Wastewater and emissions control – chemical industries European Commission IPPC Reference Document on Best Available Techniques in Common Wastewater and Waste Gas Treatment/Management Systems in the Chemical Sector; February 2003 This report covers the thermal treatment of wastes by incineration, pyrolysis and gasification. The report explicitly excludes coincineration of wastes (e.g., wastes burned as supplementary fuel in cement kilns). The Executive Summary with conclusions on BAT-associated emission levels has not been written. The European Commission Directive 2000/76/EC as mentioned above specifies a dioxin emission limit of 0.1 ng TEQ/Nm 3 for all types of waste incineration. According to the Directive, this limit is achievable with adsorption processes and oxidizing catalysts. This report presents extensive data on processes and emission controls. For dioxin control, both primary measures (e.g., good combustion practices) and secondary measures are applicable. Secondary dioxin control techniques include rapid gas quenching, oxidation catalysts, powdered activated carbon injection, combination activated carbon and lime sorbent injection, fixed bed carbon filter in the flue gas, and high efficiency dust collectors. The report notes that selective catalytic reduction applied for NOx control also reduces dioxins. One incinerator in Europe has SCR especially for dioxin control. One installation with an alkaline scrubber for acid gas control and a fixed bed carbon filter for dioxin control achieves dioxin and PCB levels below 0.1 ng TEQ/Nm 3 . Effluent from this particular scrubber undergoes two stages of treatment: physical/chemical and biological wastewater treatment resulting in dioxin levels
