Innovative approach to use polyethylene terephthalate (PET) polymer to enhance sand bentonite mixture performance in landfills Chandra, Alok
Abstract
Landfilling is one of the major techniques for the safe disposal of hazardous and municipal waste worldwide. In landfills, a sand-bentonite mixture (SBM) is usually compacted as clay covers and liners. However, due to several unavoidable factors SBM often requires additives for the enhancement. This research focuses on the applicability of two types of polymers to SBM performance enhancement: (1) Polythene terephthalate (PET) based chemically recycled polymer, i.e., Bis (2-hydroxyl) terephthalate (BHET) and (2), Xanthan gum biopolymer. At first, the required BHET polymer content in SBM specimens was evaluated based on four criteria: low hydraulic conductivity, k (200 kPa), higher split tensile strength, STS and low volumetric shrinkage, VS
