     the co-pyrolysis of waste electrical and electronic equipments (weees) and waste biomass to obtain pyrolysis-oil, a liquid fuel or chemical feedstock, was carried out in the present work. the pyrolysis-oil yield of co-pyrolysis reached 62.3% which was significantly higher than those of pyrolysis of weees and biomass alone (i.e., 53.1% for weees and 46.3% for biomass), suggesting that synergistic effects of the weees and biomass happened during the co-pyrolysis process. the pyrolysis-oil mainly contained aromatic compounds, including many aromatic hydrocarbons. more than 90 wt.% of bromides were enriched in pyrolysis-oil and char, which is easily to be recovered by further treatments, and no polybrominated dibenzo-p-dioxins and furans (pbdd/fs) were detected in all products which may be attributed to the blocking of pbdd/fs generation under special reductive environment of pyrolyisis. this work provided a green and environmentally friendly approach for the disposal of the weees as well as resource recovery.
