This report presents the results from an investigation of the emissions of dioxin-compounds that may occur from incineration of plastic waste containing brominated flame retardants (BFRs) together with waste from households and the commercial sector. The decomposition of BFRs was also investigated. The most common use for BFRs is in building materials, textiles and electronic supplies, e.g. TVs, PCs and photocopiers. In incineration plants with good combustion BFRs will decompose and form other brominated compounds, mainly hydrogen bromide (HBr). In addition, other brominated compounds will also be formed, in particular brominated organic compounds, such as dioxins where chlorine is fully or partly substituted by bromine (brominated and brominated/chlorinated dioxins).The project results presented in this report serve as a basis for authorities and the owners of incineration plants, to make decisions about whether, and under what conditions, this type of waste may be incinerated. The project was financed by the PA-group under the Nordic Council of Ministers.
