摘要

The research on innovative and efficient barrier materials for landfills continues to drive for its essential role in environmental protection. This study introduces a novel approach by examining plastic pyrolyzed char (PPC) as a sustainable additive in landfill liner systems through various geotechnical laboratory investigations like Atterberg limits, hydraulic conductivity, unconfined compressive strength, and vertical swelling test using various PPC-to-bentonite ratios to develop an optimal composite liner material. The binding mechanism between bentonite and PPC is discussed in detail based on Fourier transform infrared (FTIR) spectroscopic analysis. The findings of this study reveal that a 15% PPC addition to bentonite yields outstanding results that meet all the regulatory standards for a landfill liner. One of the significant features of this optimized mix is its improved shrinkage limit, effectively eliminating a critical issue of crack formation and propagation in traditional liner materials. This enhanced resistance to cracking results in greater durability and reliability in practical applications. Beyond its technical merits, this approach offers a sustainable solution for managing plastic waste by transforming harmful waste into valuable resources for environmental conservation. The study concludes that PPC-bentonite composite liner shows superior performance and efficient waste valorization making it a promising alternative to conventional liner materials.
