| Outline of Final Research Achievements |
Pyrolysis researches of polycarbonate, phenol resin, and epoxy resin was investigated in detail to achieve simultaneous recovery of valuable organic and inorganic materials from waste electrical and electronic equipment (WEEE). Pyrolysis mechanism for resin, interactions in resin, brominated flame retardants, and metals during pyrolysis, and effects of Ca-based additives on Br fixation to improve products quality and metal recovery rate were investigated in detail. These investigations revealed that specific pyrolysis mechanism not only resin but also resin combined with Br flame retardants and metals. In addition, Ca-based additives improve the oil and gas quality and metal recovery rates due to the fixation of Br from pyrolysates of materials.
