As an industrial waste, expanded polystyrene is being accumulated in huge amounts. The lack of reclamation sites has created the need to find methods of utilizing this waste as a construction material. In this research project, a new attempt was made to investigate the efficiency of the waste expanded polystyrene which has been reduced the volume as a lightweight fill material behind the retaining walls. The physical characteristics of the expanded polystyrene were determined and a retaining wall model test was conducted by alternately sandwiching the polystyrene between soil layers. The stable calculation of the retaining wall has also been carried out so as to examine the feasibility of the resource recycling as a retaining wall backfilling material.Recently, the municipal wasters ash discharged from the home has been increased. How to develop the technique for the decontamination and recycle from the viewpoint of environmental pollution and the lack of the final disposal space from reclamation sites is becoming an important subject. In this research project, the quality of the decontaminated municipal waster ash mixed with the Ariake clay and lime mixed is also evaluated as the soil improvement material based on the unconfined compression test.

膨胀聚苯乙烯作为一种工业废弃物，正在大量积累。由于缺乏回收场地，因此需要找到利用这些废物作为建筑材料的方法。在这个研究项目中，我们进行了一项新的尝试，研究废旧膨胀聚苯乙烯作为挡土墙后的轻质填充材料的效率。测定了膨胀聚苯乙烯的物理特性，并进行了聚苯乙烯在土层之间交替夹持的挡土墙模型试验。进行了挡土墙的稳定计算，验证了该资源回收利用作为挡土墙回填材料的可行性。最近，从家庭排放的城市垃圾灰有所增加。如何从环境污染和围垦场地缺乏最终处置空间的角度发展净化和回收技术，成为一个重要的课题。在本研究项目中，通过无侧限压缩试验，评价了净化后的城市生活垃圾灰与有明粘土和石灰混合后作为土壤改良材料的质量。
