| Summary: | The demand uses of plastic are increasing day by day leading to the various outsized amount of plastic waste producees across the world. Therefore, a proper discarding of the plastic wastes without causing any environmental risk has become a real challenge. The reuse of plastic to a beneficial product is one of the sustainable options which can secure the environment and prevent the plastic discarded to the landfill or incinerated. In this study, laboratory test was conducted to analyse the potential of recycle plastic waste as liner material in engineering application. The plastic waste was fabricated as 2mm plastic sheet liner and the geotechnical behaviors namely shear strength was analysed and compared with the commercialized liner which known as the geomembrane. Results of shear analysis showed the cohesion between the fabricated plastic waste liner (FPWL) meet the reference value for cohesion ranging 10-24 kPa. However, for internal friction most of the FPWL samples did not meet the reference value for internal friction ranging between 25-35o. This shows that plastic waste has a good shear strength and meet with global factor which feasible as alternative liner material in engineering application. © Published under licence by IOP Publishing Ltd.
