Feasibility Study on the Application of Fabricated Multipurpose Food Packaging Plastic (MFPP) Liner as Alternative Landfill Liner Material in Sustainable Landfill Infrastructure Model

Abstract

Multipurpose Food Packaging Plastic (MFPP) is one of the largest residential and commercial solid waste all over the world. BWP is categorized under Non-Biodegradable Plastic Waste (N-BPW). Due to its inability to degrade, this abundance of N-BPW caused space decrement in landfill. Many methods have been proposed for recycling of N-BPW such as incorporating N-BPW into road construction and added material in concrete production. In the present study, the feasibility of using MFPP as landfill liner material is studied through a series of laboratory testing in terms of mechanical and chemical characteristics. The liner sample was prepared in terms of a fabricated layer (combination of 60 layers (Sample A) and 80 layers (Sample B) of a single plastic). The fabricated layers were prepared by applying hot-pressing technique to increase the strength of the surface attachment between each of the layers. The prepared fabricated MFPP liners were tested for Ultimate Tensile Strength Test (UTS), Scanning Electron Microscopy (SEM) and X-Ray Distraction (XRD). The tested samples were then compared with the Conventional Geomembranes (GMs). Obtained results indicated that proposed fabricated MFPP Liner had 70% similar characteristics to GMs. In addition, the fabricated MFPP Liners have an ability to sustain maximum loading higher than Conventional GMs. These desirable characteristics indicated that the fabricated MFPP Liners has potential to be used as landfill liner material.
