Debromination of flame-retarded TV housing plastic waste

Abstract

The thermal stability and degradation kinetics of TV housing plastic and brominated fl ame retardants were studied by means of thermogravimetry. The effects of the treatment temperature on the removal rate of Br were investigated using a tube furnace reactor under isothermal and vacuum conditions. The results showed that the weight loss of TV housing plastic was divided into two stages: the thermal degradation of brominated fl ame retardants mainly occurred at 290°-350°C, and the degradation of the highimpact polystyrene resin mainly occurred at 350°-455°C. Nearly 90% of Br can be removed from TV housing plastic when the treatment temperature exceeds 280°C.

Static and dynamic flow analysis of PBDEs in plastics from used and end-of-life TVs and computer monitors by life cycle in Korea

“…This can be achieved by the aid of SFA by examining the flow of PBDEs in plastics from the devices. Among many electronic devices, TVs and computer monitors often contain high concentrations of PBDEs (Peng et al, 2010;Korea NIER, 2011). Thus, TVs and computer monitors were selected for this study to determine the flow of PBDEs in Korea.…”

Value-added products from thermochemical treatments of contaminated e-waste plastics

“…4 Removal of toxic molecules from e-waste plastics E-waste plastics a notoriously known to be tainted with toxic compounds such as BFRs and heavy metals (Tange and Drohmann, 2005;Das et al, 2009;Li et al, 2009;Peng et al, 2010;Damrongsiri et al, 2016;Debnath et al, 2018). Over the years, the European Union regulated and restricted various substances in plastics particularly in the case of electronics and electrical goods (E.U., 2015).…”

Feedstock recycling of waste polymeric material

“…Peng et al [88] investigated the pyrolysis of TV housing plastics containing brominated flame retardants. It was found that the flame retardant decomposed between 280 and 350°C, while the degradation of HIPS took place between 350 and 450°C.…”
