Development of solutions that contribute to resource recovery in Toyama prefecture.

1) NPO网络：调查人员发现没有非营利组织（NPO）“国际生态技术研究协会”来开发有助于资源回收的解决方案。这个NPO是由富山县的大学、政府和企业的研究人员于2003年9月成立的一个合作小组。这个非营利组织的目标是通过建立一个信息网络来解决环境问题，在这个信息网络中，分散在每个成员和/或组织中的知识和技术可以整合在一起。2)新型功能材料，降低环境负荷：氧化玻璃广泛应用于平板显示器（FPD）、阴极射线管（CRT）和LSI等领域。焊接玻璃的软化温度比窗户玻璃低得多，用于粘合和密封这些电子设备。众所周知，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是有毒的。欧盟通过了有害物质限制（RoHS），将于2006年开始实施。它限制了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，因为许多电子器件没有焊料玻璃就无法组装。为了开发新型焊料玻璃，研究了基于bi_2o_3的玻璃的结晶和热性能。(3)提出了一种新的资源回收工艺：拆除场地产生的废石膏板，未经分类，不含杂质，不进入回收过程，最终在控制的垃圾填埋场处理。研究人员对废石膏板的回收利用提出了一些建议。

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.
