• Optimization

  • Minimize environmental burdens or cost subject to a number of technical or policy-related constraints

Life-cycle process models

	Process model	Description
1	Landfill (LF)	Calculates emissions, material use, and energy use associated with construction, operations, closure and post-closure activities, landfill gas and leachate management, and carbon storage.
2	Waste-to-Energy (WTE)	Calculates emissions, mass flows, and resource use and recovery for the mass burn WTE process.
3	Gasification & Syngas Combustion (GC)	Calculates emissions, mass flows, and resource use and recovery for the GC process (Produced syngas from gasification is combusted to produce electricity by steam turbine).
4	Composting (Comp)	Calculates emissions, mass flows, and resource use and recovery for aerobic composting process and final use of compost.
5	Home Composting (HC)	Calculates emissions, mass flows, and resource use and recovery for home composting process and final use of compost.
6	Anaerobic Digestion (AD)	Calculates emissions, mass flows, and resource use and recovery for anaerobic digestion process and final use of compost.
7	Single-Stream Material Recovery facility (SS_MRF)	Calculates cost, emissions, and energy use associated with material recovery facilities.
8	Refuse-Derived Fuel (RDF)	Calculates cost, emissions, and energy use associated with RDF prodcution facilities.
9	Reprocessing (Reproc)	Calculates emissions, mass flows, and resource use and recovery associated with recycling materials.
10	Transfer Station (TS)	Calculates cost, emissions, and energy use associated with Transfer Stations.
11	Single Family Collection (SF_Col)	Calculates cost, emissions, and fossil fuel use associated with MSW collection.

Installation
