| Abstract: | Co-combustion tests of municipal solid waste and bromine-containing waste plastics have been performed in the TAMARA test
incinerator in order to investigate the fate of bromine in waste combustion. HBr is the main bromine combustion product. Approximately
50% of the bromine inventory stays in the grate ashes, which is much more than is found for chlorine. The percentage of bromine
transferred into the fly ash also exceeds that of chlorine. There is a strong indication that bromine has a promoting effect
upon the volatility of most of the heavy metals that are typically mobilized by chlorine.
