Federal Resource Conservation and Recovery Act (RCRA) (1976) mandated a total confinement landfill liner system coupled with a leachate treatment facility. As a result, geomembrane made of high density polyethylene (HDPE) is commonly installed along with compacted clay liner (CCL). However, due to inherent defects and difficulties during installation, detailed procedure is required for geomembrane. In addition, there is a serious problem stemming from the breakthrough of hazardous organic compounds (HOCs) via the seemingly impermeable geomembrane. It has been found that through diffusion non-polar chemical compounds could penetrate geomembrane in a matter of days. To mitigate this problem, an alternative composite artificial liner (CAL) made from recycled materials and other necessary components was developed. Crumb rubber (CR), silica fume (SF), organoclay, and epoxy binder were the main components. An environmental-friendly low volatility solvent, dimethyl sulfoxide (DMSO) was used as a plasticizer. The combination of these components makes the designed CAL not only reactive to HOCs but also pliable so that it can conform to heavy waste loading at the top and uneven settlement at the bottom.Subjects--Topical Terms:

520 $a Federal Resource Conservation and Recovery Act (RCRA) (1976) mandated a total confinement landfill liner system coupled with a leachate treatment facility. As a result, geomembrane made of high density polyethylene (HDPE) is commonly installed along with compacted clay liner (CCL). However, due to inherent defects and difficulties during installation, detailed procedure is required for geomembrane. In addition, there is a serious problem stemming from the breakthrough of hazardous organic compounds (HOCs) via the seemingly impermeable geomembrane. It has been found that through diffusion non-polar chemical compounds could penetrate geomembrane in a matter of days. To mitigate this problem, an alternative composite artificial liner (CAL) made from recycled materials and other necessary components was developed. Crumb rubber (CR), silica fume (SF), organoclay, and epoxy binder were the main components. An environmental-friendly low volatility solvent, dimethyl sulfoxide (DMSO) was used as a plasticizer. The combination of these components makes the designed CAL not only reactive to HOCs but also pliable so that it can conform to heavy waste loading at the top and uneven settlement at the bottom.
520 $a To expedite the CAL aging process, an oven was used to heat the specimens before tensile test. The United States Environmental Protection Agency (EPA) 9090 compatibility test was conducted to investigate the effect of leachate on the integrity of CAL. Diffusion experiments were performed to obtain the chemical transportation parameters. It was found that this new CAL could withstand high tensile stress (ten times larger than a typical 1.78-mm HDPE). The diffusion coefficient of the new CAL was approximately four orders of magnitude less than that of HDPE. The mass flux through the 2.5-cm thick CAL was at least three orders less than that of HDPE. The integrated Geomembrane/CAUCCL liner system could reduce the contaminant mass flux by 1.5 orders compared with the traditional composite liner. It could retard the movement of HOCs from 30 years to 280 years and allow for reuse of waste products. Other composite materials were also made, including rubber mulch and polyurethane-based mattress. From laboratory tests, these new products appeared to have excellent physical/chemical properties and commercial market potentials.
