AB  - There have been several studies showing that volatile organic compounds (VOCs) 
      can diffuse a geomembrane within days and migrate to groundwater and the 
      surrounding environment. To ease the concern of potential pollution of the 
      surrounding environment, an alternative artificial liner consisting of recycled 
      materials is proposed. This composite liner consisted of recycled crumb rubber, 
      organo-clay, silica fume, and epoxy binder. Dimethyl sulfoxide, an 
      environmentally-friendly solvent recycled from paper pulp, was used as a 
      plasticizer. The objective of this study was to determine the best combination of 
      ingredients used at the initial stage and to develop artificial liners suitable 
      for containing VOCs in leachate by comparing various physical properties. A 
      series of screening tests including bending, tearing and elongating was performed 
      to determine the most suitable mixture ratios. Then, more intensive tests were 
      performed with the specimens that had the best physical properties. The new 
      artificial liner demonstrated satisfactory mechanical properties with the minimum 
      elongation and maximum strength after 40 years. Both artificial liners and 
      high-density polyethylene (HDPE) specimens had ~136 kg cm(-2) after 4 months of 
      thermal stress while the artificial liner had 40% less elongation at break than 
      HDPE. The artificial liner's fully developed strength was about ten times 
      stronger than HDPE. This new type of composite material that can be applied on 
      site may provide a new perspective in liner design and alleviate the issue of 
      potential groundwater pollution caused by landfill leachate and highly mobile 
      VOCs which is a matter of much concern.
