The influence of soft plastic in shear strength analysis of municipal solid waste

ABSTRACT

This thesis presents an analysis of the shear strength of municipal solid waste with reduced thermoplastic in landfills. Through laboratory testing was performed a comparative analysis between the two main thermoplastics (high and low density polyethylene) present in Brazilians landfills. It investigates the variation of the strength parameters of MSW if plastic bags are removed from supermarkets from tensile tests of plastics and direct shear tests of samples prepared with different percentages of mixed plastics to a granular material simulating solid waste stabilized,. The results confirm the importance of plastics, because they are responsible for the high values of strength parameters due to tensile forces caused by these fibers.
