Abstract: | Life-cycle assessment concepts and methods are currently being applied to evaluate integrated municipal solid waste management
strategies throughout the world. The Research Triangle Institute and the U.S. Environmental Protection Agency are working
to develop a computer-based decision support tool to evaluate integrated municipal solid waste management strategies in the
United States. The waste management unit processes included in this tool are waste collection, transfer stations, recovery,
compost, combustion, and landfill. Additional unit processes included are electrical energy production, transportation, and
remanufacturing. The process models include methodologies for environmental and cost analysis. The environmental methodology
calculates life cycle inventory type data for the different unit processes. The cost methodology calculates annualized construction
and equipment capital costs and operating costs per ton processed at the facility. The resulting environmental and cost parameters
are allocated to individual components of the waste stream by process specific allocation methodologies. All of this information
is implemented into the decision support tool to provide a life-cycle management evaluation of integrated municipal solid
waste management strategies. |
