Emission Measurements During Incineration of Waste Containing Bromine

image of Emission Measurements During Incineration of Waste Containing Bromine

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.

Results

The combustion conditions were normal during sampling and measurement at the Klemetsrud plant, with CO-levels of approximately 20-30 mg/Nm3. CO-levels during sampling at FREVAR Plant were approx. 50 mg/Nm3. At the Energos Plant, CO was not detected during measurements, which indicates a very effective combustion.
