|Landfill Bioreactor Performance, Second Interim Report, Outer Loop Recycling and Disposal Facility, Louisville, Kentucky (240 pp, 4.53 MB) (EPA/600/R-07/060) September 2006
A bioreactor landfill is one that increases the rate and extent of waste decomposition, gas generation, and settlement compared to a traditional landfill. This report was prepared to provide an interpretation of field data collected as part of a multiyear Cooperative Research and Development Agreement (CRADA) between EPA and Waste Management, Inc. (WM). The CRADA was established to evaluate the performance of landfill bioreactor units at the WM Outer Loop Landfill in Louisville, Kentucky. This report follows the first interim report of September 2003, which presented a complete description of the landfill study sites and the data collection procedures.
This project considers solid waste decomposition, moisture balance, landfill gas generation, and leachate quality to evaluate the effect of bioreactor operations on municipal solid waste decomposition. Three types of landfill cells were evaluated in this study:
The monitoring data were sequentially evaluated to identify trends in solid waste decomposition, moisture retention, landfill gas quality and quantity, and leachate quality. The data presented in this report are limited in terms of establishing long-term trends in the operation of bioreactor landfills.
