Abstract – The scientific disposal of large quantities of Municipal solid waste is a challenging problem in cities in most of the countries. The Pirana landfill in Ahmedabad is one of the biggest dump yards in the city being spread over an area of 65 acre of land. Reclaiming and using this humongous amount of soil in form of highly degraded organic as well as inorganic contents as engineering material becomes an innovative solution to the geo-environmental problems. The MSW from Pirana landfill is found to be mostly sandy soil. The potential cementitious properties of MSW is tried to enhance by addition of leachate. Thus working towards improving the cohesion and compressibility of MSW, shear tests and consolidation tests are performed on the MSW with addition of different concentrations of leachate varying in concentrations of 10%, 25%, 50%, 75%, and 100% of OMC. The box shear tests showed considerable increase in cohesion with the addition of leachate whereas the value of internal friction was found to decrease with increase in the leachate quantity. The value of compression ratio also was observed to reduce with the addition of leachate. Enhancement of cohesion of MSW is studied by further adding chemical admixture into leachate.
