A Management Method for Toxic Brominated Compounds Contained in Waste Plastics - Development of Safety Incineration and Effective Monitoring Technologies -

用于风险管理的阻燃剂环境信息很少。它们的成分复杂，难以测量。因此，阻燃剂的环境管理还没有得到足够的进展。溴系化合物的毒性被认为与氯系化合物相当，阻燃剂的生产量很大。然而，溴化化合物如溴化阻燃剂尚未出于环境保护的目的而受到控制。本研究通过实验室规模的阻燃剂焚烧实验，探讨了阻燃剂在实际工业废物处理设施中安全有效处理的可能性。本研究的使命如下：1）开发有效的废气和鱼苗灰中溴代化合物的监测技术; 2）明确安全焚烧条件，防止有毒溴代化合物的产生; 3）实际工业废物处理设施的应用从结果来看，各种工程因素，如焚烧温度、空气流量等，考察了它们的含量，并确定了适宜的反应条件。这些条件被认为适用于实际的工业废物处理设施。

Environmental information of flame retardants for risk management have been little. Their components are complicated and are difficult to measure. Therefore, environmental management of flame retardants have not been in progress enough yet. Toxicity of brominated compounds are suspected as equal to that of chlorinated compounds, and the production volume of flame retardants are very large. However, brominated compounds such as brominated flame retardants have not been controlled for the purpose of environmental protection. Therefore, development of suitable management technologies is expected urgently.In this study, a laboratory scale experiment on incineration of flame retardants were tried to clarify the possibility of their safety and effective treatment in actual industrial waste treatment facilities. The mission of this study was set as follows ;1)To develop the effective monitoring technology for brominated compounds contained in exhaust gas and fry ash.2)To clarify the safety incineration condition to prevent the production of toxic brominated compounds3)Application of actual industrial waste treatment facilitiesFrom the results, various engineering factors, such as incineration temperature, air flow volume rate and so on, and their level were investigated and the suitable condition were clarified. These conditions were considered to apply to actual industrial waste treatment facilities.
