Plastic media blasting PMB is a process employed by the Air Force and others to strip protective coatings from aircraft and other equipment. The waste is made up of about 90 plastic medium and 10 paint residue, when garnet is not used. The plastic medium, being an organic material, can be thermally decomposed into gaseous components that can be released, thus reducing the waste to be disposed of to a fraction of the untreated waste. The results of a pilot test in a fluid-bed reactor treating two combination streams of PMB waste are presented, including life cycle and cost analyses associated with operation. The cost analyses indicates the fluid bed reactor thermal treatment process can be cost-effective in some cases when compared to direct landfilling. jg p4
