1.研究開発の内容及び成果等
本研究では、今後大量廃棄が予想されるPVシステムのリサイクル処理手法の確立に向けて、低コストかつ各種モジュールに対応可能な汎用リサイクル処理技術を開発すると共に、広域的な回収法やリサイクル取り扱い規定の法制化及び規制緩和等、新たな社会システム構築のための提案とその基礎検証を行なう。
英文要約Title: Development on PV recycling system for some wide-area (FY2010-FY2012) FY2010 Annual Report
Aiming at establishment of a PV recycling system, we have started a development of low cost universal recycling processes applicable to various types of PV modules and a LCA study and proposing a social system desired for the PV recycling system. Outline of the development and the studies in fiscal 2011 are as follows. For the development of low cost universal recycling processes, we have improved the prototype of the back-sheet remover installed last year to be applicable to various types of PV modules and newly made prototypes of an aluminum-frame remover and an EVA-thermal decomposition apparatus and a CIS metal film scrapping apparatus from glass substrate. As a result, most of the recycle processing apparatuses have been made. Regarding the LCA study, we evaluate waste treatment and recycling for polycrystalline silicon solar modules. The results show that CO2 is reduced approximately the range of 20 - 220 CO2-kg/kW differing from level of recycling compared with the current condition, we suggest the necessity for heat recovery from EVA combustion and glass recycling as plate-glass cullet and silicon as polycrystalline silicon in CO2 reductions. Glass recycling contributes significant reduction for landfill waste. In case glass is recycled effectively, reduced landfill waste is estimated 650 ton on 2020 and 6,400 ton on 2030 in Kyushu region. Concerning the social system, we interview some actual players involved with the PV recycling system both domestic and overseas, and propose the example form of PV recycling scheme based on the interview survey, etc. In addition, we assume realistic transportation distance from residence buildings to a recycling plant via collection points and we estimate cost in logistics model. As results, it costs 4,400 JPY when 30km primary transportation distance(from residence building to collection point)and 3,600 JPY when 20km primary transportation distance. As for legal systems, we investigate the integrated certified waste management system in detail, because the system is necessary to take back of PV modules spread widely. As the results, it is founded that 1) most of waste PV modules from houses are referred to as industrial waste in current situation, 2) industrial waste which is stable and safety like PV modules seems to be target of the integrated certified waste management system. However even if waste PV modules were referred to as target of the system, it is necessary for PV module industries to agree with taking back system of waist PV modules spread widely by themselves like PV CYCLE Association in Europe. That is most important and challenge in Japan.
