In this study, a rational disposal system for an effective utilization of municipal solid waste (MSW) was considered from the experimental and analytical approaches. The following conclusions were obtained :1)Evaluation of environmental impact and material costs for recycle geo-materialsA fundamental idea was presented for estimating the environmental an material costs of recycle geo-materials by introducing the new methodology of life cycle assessments (LCA).Based on the fundamental idea, a rational financial estimating model was also presented including the environmental costs, and the model was applied to predict the construction material costs in future. The importance of newly structure of material recycling society was pointed out through the results of prediction,2)Utilization of MSW as a mixed geo-materialA geo-material which was made by burning the materials after mixing the MSW with clayey soils was newly developed.3)Stabilization of heavy metal behaviours of MSW ground by inner water circulationThe early stabilization of heavy metal behaviours of MSW ground in the shore of the sea by inner water circulation was clarified through some model tests and analytical considerations.

本文从实验和分析两方面探讨了合理的城市生活垃圾处置体系，以实现城市生活垃圾的有效利用。研究得出以下结论：1)循环土工材料的环境影响和材料成本评价通过引入生命周期评价（LCA）的新方法，提出了循环土工材料环境和材料成本评价的基本思路。在此基础上，提出了包括环境成本在内的合理的财务估算模型，并应用该模型对未来的建筑材料成本进行了预测。通过预测结果，指出了材料循环社会新结构的重要性。2)城市生活垃圾作为混合土工材料的利用。新开发了将城市生活垃圾与粘性土混合后燃烧制成的土工材料。(3)内水循环对城市生活垃圾地基重金属特性的稳定作用通过一些模型试验和分析考虑，阐明了内水循环对滨海城市生活垃圾地基重金属特性的早期稳定作用。
