The gasification recycling technology of plastics WEEE containing brominated flame retardants

摘要

The recycling of WEEE (waste electrical and electronic equipment) became a requirement in April 2001 in Japan under the Home Appliance Recycling Law. By 2008 the criterion for the recycling ratio will be raised to 80%-90%, and at that time plastic must also be recycled. For this work, gasification processes (feedstock recycling technology) were selected for plastics WEEE recycling. After high temperature treatment, at over 1200℃, shock cooling of the gases to a temperature of roughly under 200? was done by this process. The generated 'thin' gas could then be used as raw materials for chemical industries or for electric power generation. The effect of the high temperature treatment and the shock cooling suppresses the emission of brominated dioxins to a very low level, just as for chlorinated dioxins.
