New Recovery Technology of Valuable and/or Toxic Metals by Utilizing Industrial Waste Incineration Kiln

在本研究中，为了回收含有有价值的资源和有毒金属的废旧产品，在与传统垃圾处理行业的合作下，工业垃圾焚烧炉成为重点和积极的研究对象。在“含贵重资源和有毒金属废旧产品的物流分析及其环境负荷势分析”和“含贵重资源和有毒金属废旧产品的物流分析及其环境负荷势分析”中，对95种家用电子产品的国内发货量、产品平均重量、国内弃置量和国内弃置量进行了估算。此外，收集、拆解和测量了贵重资源和有毒金属的物质含量和洗脱量。在《含贵重资源和有毒金属的电路板安全焚烧技术的开发》中，电子产品的电路板和覆盖体中含有的阻燃剂在焚烧过程中产生有毒物质。特别是对有毒的焚烧产物一氧化碳(CO)和半非挥发性有机溴化物(SNVOBR)在不同的实验条件下进行了测试，如电路板类型、阻燃剂类型、焚烧废物量、焚烧温度、气体接触时间等。

In this research, in order to recycle used products, which contain valuable resources and toxic metals, industrial waste incineration kiln was focused and investigated positively under cooperation with conventional waste treatment industries. Two kinds of researches were done in order to develop a new engineering system for of valuable and toxic substances ; "material flow analysis of used product containing valuable resources and toxic metals and its environmental load potential analysis" and "development of safety incineration technique of circuit board containing valuable resources and toxic metals".In "material flow analysis of used product containing valuable resources and toxic metals and its environmental load potential analysis", number of domestic shipment, product average weight, number of domestic disposal, and domestic disposal weight were estimated for 95 items of home electronic products. Moreover, products with large domestic disposal weight were collected, disassembled, and measured material contents and elution amounts of valuable resources and toxic metals.In "development of safety incineration technique of circuit board containing valuable resources and toxic metals", generation of toxic substances produced in incineration of flame retardants which were contained in circuit board and covering body of electronic product. Especially, toxic incineration products, such as carbon monoxide (CO) and semi-non volatile organic brominates (SNVOBr), were measured in various experimental conditions, such as type of circuit board, type of flame retardant, amount of incineration waste, incineration temperature, gas contact time, and so on.
