A great variety of plastics are used in IT products, which differ not only by plastic type but also by color and presence of additives such as brominated flame retardants (BFRs). In this study, to identify the plastics containing BFRs and heavy metals (i.e., Pb, Hg, Cd, Cr6+), laser-induced breakdown spectroscopy (LIBS) was used. Polypropylene (PP)-type black plastic samples that were obtained from three different types of used electric cookers were analyzed. The spectrum peaks observed in the LIBS system confirmed the presence of BFRs and heavy metals. The number of Br peaks were identified and the data were compared with the previous atomic spectra database. In the near future, the recycling of plastics from e-waste may become more important not only to reduce the amount of waste requiring treatment but also to eliminate the plastics containing hazardous components and compounds.
