Role of Japan′s Compliance Leaching Test for Landfills and Related Issues

Abstract

Solid waste landfills must be appropriately managed so as to prevent the adverse effects on the surrounding environment. Japan′s compliance leaching test for industrial wastes, JLT-13, is used as a means for judging whether leaching of hazardous substances is an issue at solid waste landfills. This report summarizes the role of JLT-13 and other related issues based on recent findings and information. The leaching test is still a prerequisite for securing the environmental safety of any landfill. Moreover, in order to set into place the concept of a material-sound society, the construction of a basic concept ualization/guideline for environmental safety in soils, recycled materials and wastes must be developed.
