项目摘要

1) NPO network : The investigators found no profit organization (NPO) "International association of ecotechnology research" to develop solutions that contributes resource recovery. This NPO is a collaboration team established in September 2003 by the researchers from universities, governments and industries in Toyama prefecture. The aim of this NPO is to solve environmental problems by establishing an information network in which the knowledge and technology scattered in each member and/or organization can be integrated.2) Novel functional materials to decrease environment loads : Oxide glasses are extensively applied to some electric field such as flat panel display (FPD), cathode ray tube (CRT) and LSI. Solder glasses have much lower soften temperature than window glass and are used to bonding and sealing these electric devices. It is known that these solder glasses have contained lead oxides as a major component. However, it is said that lead compounds are toxic environment. European Union adopted Restriction on hazardous substances (RoHS) which will be operated from 2006. It constricts use of hazardous substances such as lead compounds. Solder glasses are an indispensable material in electronic industry, because many electric devices can not be assembled without solder glasses. In order to develop new solder glasses, the investigators were investigated crystallization and thermal properties of glasses based on Bi_2O_3.3) Proposal of novel resource recovery process : Waste gypsum boards generated from demolition sites that is not sorted nor has impurities attached does not enter the recycling process, so it was ultimately disposed of at controlled landfill sites. The investigators was developed some proposal to recycle waste gypsum boards.

1）NPO网络：调查人员发现没有盈利组织（NPO）“国际生态技术研究协会”开发有助于资源回收的解决方案。该NPO是由来自富山县的大学、政府和产业界的研究人员于2003年9月成立的协作小组。该NPO的目的是通过建立一个信息网络来解决环境问题，在该信息网络中可以整合分散在每个成员和/或组织中的知识和技术。2）减少环境负荷的新型功能材料：氧化物玻璃广泛应用于某些领域平板显示器（FPD）、阴极射线管（CRT）和LSI等电场。焊料玻璃的软化温度比窗玻璃低得多，用于粘合和密封这些电子器件。已知这些焊料玻璃含有氧化铅作为主要成分。然而，据说铅化合物对环境有毒。欧盟通过了有害物质限制（RoHS），将于 2006 年开始实施。它限制铅化合物等有害物质的使用。焊料玻璃是电子工业中不可缺少的材料，因为许多电子器件的组装离不开焊料玻璃。为了开发新型焊料玻璃，研究人员研究了基于 Bi_2O_3.3) 的玻璃的结晶和热性能。提出了新颖的资源回收工艺：拆除现场产生的废石膏板，未经分类，也没有附着杂质，不会进入回收过程，因此最终在受控垃圾填埋场处置。调查人员制定了一些回收废石膏板的建议。
