Abstract
This work will provide the lifetime of High-Density Polyethylene (HDPE) geomembranes in contact with leachate and stillage (residues typical of environmental works). The samples are exposed to the waste in the laboratory by periods (1, 2, 3, 4, 6, 8, 10, and 12 months) at elevated temperatures of 85, 75, 65, and 55 degrees. The physical and tensile properties and oxidation time (OIT) of m…
