A Decision Support Model For Municipal Solid Waste Recycling At United States Air Force Installations, Gergory A. Williams
A Decision Support Model For Municipal Solid Waste Recycling At United States Air Force Installations, Gergory A. Williams
Theses and Dissertations
The United States Air Force requires each installation to operate a municipal solid waste recycling program. Two inherently conflicting objectives, waste material diversion and financial result, have been established for the program. Reducing landfill disposal is the primary objective, but the incentive for profit is strong because each installation can retain profits from the program. Installations can be divided into two distinct areas, commercial and residential, based on the waste stream composition and funding. Structuring of the recycling program is often done in an ad-hoc manner. A decision support model was developed to evaluate four methods for each area. The …
