There is disclosed a process for debromination of novel brominated flame retardants (NBFRs) through co-pyrolysis with zinc oxide (ZnO) and franklinite (ZnFe.sub.2O.sub.4) to effectively restrict brominated species emission from NBFRs during thermal degradation. The method addresses environmental concerns by converting tetrabromobisphenol A 2,3-dibromopropyl ether (TBBPA-DBPE) and tetrabromobisphenol A diallyl ether (TBBPA-DAE) into bromine-free hydrocarbons. Utilizing Zn-based metal oxides from electrical arc furnace dust (EAFD), this process transforms them into metal bromides, facilitating selective zinc extraction. Thermogravimetric analysis guides pyrolysis at up to 500 C., revealing ZnO's efficacy in capturing 92% of HBr gas and producing minimal brominated compounds (relative area, 0.83%). Phenol emerges as a significant condensable product, while inorganic gases and methane dominates the non-condensable fraction. The retained metal bromides in pyrochar and <8% HBr gas emissions underscore ZnO's debromination potential. This method also suggests ZnO's application for dehalogenating other polymers and using spinel ferrites in combating brominated polymers.
