A waste stream may be defined as hazardous under RCRA if it meets certain criteria for ignitability, corrosivity, reactivity, or toxicity, or if the waste stream is specifically identified by EPA as a hazardous waste. An individual waste stream is subject to being classified as hazardous (listed) if it contains any one of approximately 375 chemicals identified by EPA as hazardous constituents. These designated chemicals are frequently referred to as Appendix Vlll compounds because of where they are listed in the published regulation. 

The waste-disposal flow diagram illustrates the waste streams for which there is no further economic use in the plant (see Section 1.3) and indicate their flow numbers from the process flow diagram. Precise information should be given on the toxicity, degradability, water danger, flash point, ignition temperature, MAK, odor threshold, etc. of the individual components, their mass flows, and the state of aggregation of the flow (viscosity, sediment content, etc.). This information makes it possible to specify the type of waste disposal required with consideration of site-specific and economic factors, for example ... 

Common controls. Proper hazardous waste management is crucial for minimizing risks to employee health and the environment. Employers must make an effort to properly characterize all waste streams to determine which ones may meet the criteria for being classified as hazardous (ignitability, corrosivity, reactivity, toxicity, or listed). Site characterization, analysis, and control are required to identify specific hazards, to determine the appropriate health and safety control procedures needed to protect employees from identified hazards, and to control the hazardous exposures to employees before cleanup begins. 

In the calciner, the liquid waste is pneumatically atomized from three nozzles at 85-140 gph into the heated 6-ft-deep fluidized bed of solidified granular waste at 400°-500°C. The process is endothermic therefore the bed is heated by in-bed combustion of an oxygen-atomized stream of kerosene. The process is started with a bed of granular material such as dolomite, which is replaced by calcine as the operation continues. By preheating the bed with externally-heated fluidizing air to a bed temperature of 360°-400°C, the atomized kerosene will ignite in the presence of a nitrate waste. 

The central cooling air is used to cool down the central plate of the burner tip and to supply oxygen in a flame core to help the solid/liquid waste fuel burning. The dispersion air stream is used for better pulverization of the PF jet, fast ignition, and quick response of the flame to primary air modification. The swirling air stream keeps the unburnt fuel and devolatized nitrogen inside of IRZ, witch becomes reach in reducing species able to control both fuel bond and thermal NO. ... 

Benzoyl peroxide is diluted in water and disposed of in a large flowing stream of water. Another common method of disposal is to spread the material over a large area on the downwind side of a pit. The waste solvent is fed to the pit and ignited carefully from a remote position (Armitage and Strauss 1964). The solvent will bnm and decompose the dispersed peroxide.
