The occurrence and the significance of agglomeration phenomena during thermal treatments in a fluidized bed reactor of a couple of plastic wastes were studied. A small scale bubbling fluidized bed, made of quartz, was charged with pellets obtained from mono-material collections of polyethylene and polyethylene terephtalate. Batchwise and continuous experiments were carried out at different bed temperatures (from 450 to 850 C), under inert and oxidizing conditions and by operating the reactor with silica sand having a size range of 0.3--0.4 mm. Different mechanisms of defluidization were identified and characterized. The time at which the phenomena occurred, for each of bed temperatures used, was also determined. In particular, the continuous experiments showed that defluidization can occur, with different mechanisms, at temperatures lower than 850 C. An increase of bed temperature as well as that of oxygen content strongly reduces the potential concern of particle agglomeration and bed defluidization.
