Comparison between Jap. & Ital.Landfill and study of New

根据对日本和意大利最后处置场址的调查所收集的资料，研究了下列文章：通过对福冈市和卡利亚里市部分最终处理场的产气和渗滤液数据的分析，阐明了产气和渗滤液的理化性质。从两国对衬砌系统的调查来看，如何防止渗漏和对地面土壤的污染正在进行研究。讨论了最终处置场地的抗震安全性，并澄清不会发生再要求。如何保护最终处理场周边地区不受环境污染已经进行过研究，研究仍在继续，目前取得的结果已在KNCT（1998）研究报告的论文中报告。对两国最后处置场址的最终土地使用的实际情况进行了调查，以便制定一种更有用和合理的方法。cossu教授应邀到KNCT讨论联合研究的成果，并互相交流有用的资料。为了提出固体废物最终处置的新制度，今后将继续积极开展联合研究。

On the basis of information collected from the investigation of final disposal sites both in Japan and Italy, the following articles have been studied.1. From the data of Generated Gas and Leachate from some final disposal sites in Fukuoka-City and Cagliari-City, the physical and chemical properties ofGenerated Gas and Leachate are clarified.2. From the investigation of the Lining Systems in both country, how to protect the leakage and the contamination of ground soil are being studied.3. The safety of requefaction of final disposal sites against earthquake and clarification that requefaction will not occur, were discussed.4. How to protect the surrounding area of final disposal sites from environmental pollution has been studied and studies are still continuing, the results obtained so far have been reported in the paper of the research report of KNCT(1998).5. The actual circumstances of ultimate land use of final disposal sites in both countries has been investigated in order to develop a more useful and reasonable method.6. Prof.R.Cossu was invited to KNCT to discuss the results of the Joint Research and exchange useful information with each other. In order to present a new system for final disposal sires of solid waste, Joint Research will be continued actively in the future.
