Abstract
This article addresses the feasibility of a new landfill category known as reclamation type landfill, which uses inert waste materials. After reviewing previous research, waste materials and by-products appropriate for this category were selected in terms of their geotechnical properties. Environmental and economical feasibilities were analyzed by optimizing the waste management strategy under a specific scenario, taking into consideration environmental costs from CO2 emissions, land conversion and so on. Although some technical and institutional issues still remain, results indicate that this new landfill category could be realized economically by considering indirect environmental costs. In addition, the basic concept of environmental suitability assessment for reclaimed waste-based materials was discussed, For this, we referenced relevant technical guidelines and manuals in which environmental risk-based approaches specific to site conditions and material properties were employed for reused/recycled materials in geotechnical applications.
