PacificNorthwestLaboratory Richland,Washington 99352 "* SUN4ARY This report describes a Macro Material Flow Modeling (MMFM) concept and approach that are being adopted to develop a predictive modeling capability that can be used as the basis for evaluating potential impacts from various solid waste management system configurations and operating scenarios, as well as the impacts of various policies on solid

This capability, as part of a broaderSolidWaste Initiative at Pacific NorthwestLaboratory, is intendedto providean increased understanding of solidwaste as a disposal,energy,and resourceproblemon a nationaland globalscale,particularly over the long term. The resultsof this increased understanding will eventually have an impacton a varietyof U.S. federal government activities, as well as on the activities of other entities. This increasedunderstanding will also help providethe basis for subsequent activities under the SolidWaste Initiative. The reportdescribescurrentsolidwastemanagementpracticesand their context,definesquestions of interestrelatingto these practices,and proposesan approachthat couldbe employedto analyzethese practicesand possiblealternatives to them. A preliminary review,analysis,and summaryof available data to support this approach are also provided. To include all of the relevant drivers that affect solid waste production, management,and disposition options, the proposed approach extends beyondthe solid waste management system to also encompassthe whole materials production and use cycle. This allows consideration of policies and approaches that directlyimpactmaterialand waste flows (e.g.,materialuse and/ortransportation bans and bottlebills)as well as thosethat indirectly impactmaterialand waste flows (e.g.,via economicand indirectregulatory drivers). Thus, the MMFM capabilityshouldproveusefulto a broad rangeof peoplewith interestsin solidwaste, including statesolidwaste planners, policymakers,regulators, engineers,and economists. The reportis intendedto providethe basisfor the development of a specificmodelingarchitecture, includinginput/output specifications, data flows,and code structures, to achievethe MMFM concept. A simpledemonstrationprototypeof the model Is also planned,simulating major portionsof the model functionality, to providea basis for presentingand refiningthe modelconcept,confirming the operability of the model and the usefulness of the results,and facilitating liaisonactivities with prospective clients. Subsequentreportsin this serieswill reporton the developmentand " application of the MMFM concept. iii ACKNOWLEDGHENTS Thts report and the modeltng concept described in tt could not have been developed without the contributions of a number o6 individuals. The authors are grateful for these numerouscontributions and wish to specifically acknowledgethe following. • Jack HcElroy and Gary HcNair of the PNLWaste Technology Center have consistently provided strong management support for the Solid Waste [nltlatlve. Without their support, the [nltlatlve would probably not have been undertaken. The Global Studies program at PNLprovided Important guidance and direction In the Inltial development of the Solid Waste Initiative. Within this group, the authors specifically wish to recognize the guidance and encouragementreceived from Gerry Stokes, John Clarke, and Brad Ashton. An internal PNLworkshopwas held during the development of this modeling concept to gather broader input from throughout the Laboratory. Participants tn thts workshopwere Htke White, Jtm Thomas,Hark Whiting, Joe Roop, Jtm Buelt, NancyHasstg, and John Ttxter. Besides participating in this workshop, Htke White served as a sounding board and critical reviewer for the authors throughout the development of the tdeas presented tn this report. The literature search and review support provided by Helissa Pellets and Hiche]e DeWeeseand the editorial support provided by Dave Payson are gratefully acknowledged.
