Abstract

Geomaterials using waste materials have been developed in the geotechnical engineering field. It is important to clarify immobilisation effect of harmful substances and the extent of environmental load of these geomaterials. In this study, laboratory tests for investigating the leachate and mechanical properties are carried out on four types of geomaterials with immobilisation treatments for heavy metals: cement-treated soil, baking solidification material, plastic melting solidification material and mixture with charcoal. A parameter for representing recycling efficiency is proposed in consideration of the utilisation of waste and CO 2 emission in the manufacturing process of the geomaterials. The recycling efficiency of composite geomaterials is calculated using MSW (Municipal Solid Waste) incineration bottom ash, and its environmental impact is evaluated.
