SYNOPSIS: Currently, there are more than three thousand landfills in the United States in which approximately 55% of the municipal solid waste (MSW) generated is being disposed. The majority of these landfills are designed on the premise that liquid generation should be minimized through the design of liner, leachate collection and removal, and final cover systems. Recently, “bioreactor” landfills are being designed on the contrasting premise that leachate recycling, water addition, and other operating strategies should induce an enhanced environment for biochemical degradation of MSW.  Bioreactor landfills are receiving a great deal of attention from environmental professionals because they offer a sustainable way to achieve increased waste degradation along with benefits such as reduction in leachate pollution potential and rapid increase in landfill volumetric capacity.  They also offer significant reductions in post-closure management as a result of a reduced period for landfill leachate and gas generation and improved potential for more rapid land reuse for a recreational facility or industrial park. The design of bioreactor landfills requires a careful assessment of several engineering aspects such as leachate/moisture distribution, waste degradation and properties, waste settlement, and stability of waste slopes.  These issues will be presented and discussed in light of several on-going projects involving field monitoring, laboratory testing and mathematical modeling at the University of Illinois at Chicago.

BIOGRAPHICAL SKETCH: Dr. Krishna Reddy is a Professor of Civil and Environmental Engineering at the University of Illinois at Chicago (UIC). Dr. Reddy received his Ph.D. from the Illinois Institute of Technology, Chicago. He received gold medals for being first in his class of B.S. (Civil) in Osmania University and M.S. (Geotech) in Indian Institute of Technology, Roorkee. Dr. Reddy is a professional engineer in the State of Illinois and he worked as civil engineer and project manager in consulting engineering companies for several years prior to joining the UIC. Dr. Reddy's consulting and research expertise includes geotechnical engineering, remediation of contaminated sites, waste containment systems, and waste material characterization and reuse. Dr. Reddy has published over 150 technical papers on various topics in geotechnical and geoenvironmental engineering. He is also the co-author of the book "Geoenvironmental Engineering: Site Remediation, Waste Containment, and Emerging Waste Management Technologies" published by John Wiley in 2004. Dr. Reddy is the Editor of Land Contamination & Reclamation journal, and he serves on the editorial boards of the Journal of Soil and Sediment Contamination, Journal of Geotechnical and Geoenvironmental Engineering, and Journal of Hazardous Materials. He has received several awards and honors for excellence in teaching, research, and professional service. See www.uic.edu/~kreddy for more information.
