Abstract
The Corinth landfill closure project was the first in New York State to use paper sludge as alternative barrier layer material in a landfill cap. The use of paper mill sludge in the cap reduced cost relative to a conventional clay or geomembrane cap system. The beneficial reuse of the paper sludge also saved landfill space. To demonstrate the feasibility of using paper sludge as barrier layer material, extensive research was conducted to evaluate the physical properties of the sludge, primarily hydraulic conductivity. Centrifuge model tests were conducted to simulate infiltration through the cap over a 30 year period. Centrifuge modeling was used in lieu of field test sections, at significant saving in time and cost. Paper sludge behaves similar to a highly organic peat soil. It has high water content, is highly compressible, and its hydraulic conductivity is a function of the organic content of the material. These characteristics impacted cap design and construction methods. This paper summarizes the research performed for this project, including centrifuge testing. Cap design is discussed, taking into consideration the properties of the sludge. Construction of the landfill cap is described, including construction techniques and QA/QC protocol. Barrier layer QA/QC data are summarized. Physical properties of the paper sludge are emphasized herein; analytical data are not included.
