Utilization of Municipal Solid Waste from Okhla Landfill as a Highway Embankment Material

Abstract

Municipal solid waste (MSW) is a heterogeneous mix of discarded materials that differ in their properties. The disposal and management of municipal solid waste in cities have become a serious concern all over the world. Using this refuse in the building of roads and highways will be an innovative technology as it will not only help in eradicating a huge proportion of openly dumped wastes but also reduce the increasing pressure on the natural road building materials. It is a relatively new idea as no road has entirely been constructed from municipal solid waste. For successfully adopting municipal solid waste as a building material in road sector that will route to sustainable growth, the feasibility must be established and this emphasizes on the dire importance of its geotechnical characterization. This paper gives a detailed review about the previous finding of geotechnical properties of municipal solid waste studied worldwide and results of physical, geotechnical and chemical properties of municipal solid waste from Okhla Landfill. The analysis of results showed that municipal solid waste from Okhla Landfill can be utilized as a highway embankment material.
