Green Thermal Degradation of Used Printed Wiring Boards

该奖项由2009年美国回收和再投资法案(公法111-5)资助。本研究的主要目的是了解印刷线路板(PWB)废物的分解反应、方案和途径，通过这些途径获得清洁和有用的燃料产品；找到合适和有效的催化剂来燃烧和热解印刷线路板(PWB)废物，以控制有毒气体和重金属的排放；以及提出工业规模的印刷线路板废物回收的绿色工艺。燃烧和热解都将被研究。最终目标是为印制板废料创造一种高效和环保的热处理工艺，通过提取燃料、回收贵金属和避免工艺污染来回收其中所含的能量。研究生和本科生都将参与这项研究。每个春季学期将开设“电子废物回收利用”网页，开设材料回收利用课程。

Both combustion and pyrolysis will be investigated. The ultimate goal is to create an efficient and environmentally friendly thermal treatment process for PWB wastes to recycle the energy contained therein by extracting fuels, recovering precious metals, and avoiding pollution from the process. Both graduate and undergraduate students will participate in the research. A homepage on "Recycling of Electronic Wastes" will be built, and a course on the recycling of materials will be taught every spring semester.
