SwolfPy's Life-Cycle Process Models
The source code & input data of the life-cycle process models are available on SwolfPy Project's GitHub repository.
| Process Model | Description | Source | |
|---|---|---|---|
| 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. | Based on Wang et al. (2021). |
| 2 | Waste-to-Energy (WTE) | Calculates emissions, mass flows, and resource use and recovery for the mass burn WTE process. | Based on an updated version of Harrison et al. (2000) that includes aluminum recovery in the bottom ash and heat losses to moisture and ash. |
| 3 | Gasification & Syngas Combustion (GC) | Calculates emissions, mass flows, and resource use and recovery for gasification and syngas combustion process. | Based on Sardarmehni and Levis (2021). |
| 4 | Composting (Comp) | Calculates emissions, mass flows, and resource use and recovery for aerobic composting process and final use of compost. | Based on Levis and Barlaz (2013) & Hodge et al. (2016). |
| 5 | Anaerobic Digestion (AD) | Calculates emissions, mass flows, and resource use and recovery for anaerobic digestion process and final use of compost. | Based on Levis and Barlaz (2013) & Hodge et al. (2016). |
| 6 | Home composting (HC) | Calculates emissions, mass flows, and resource use and recovery for aerobic home composting process and final use of compost. | Developed using data from Colón et al. (2012) & Andersen et al. (2010). |
| 7 | Single-Stream material recovery facility (MRF) | Calculates cost, emissions, and energy use associated with material recovery facilities. | Based on Pressley et al. (2015). |
| 8 | Refused-derived fuel (RDF) | Calculates cost, emissions, and energy use associated with RDF production facilities. | It is based on Pressley et al. (2014) and updated in Sardarmehni and Levis (2021). |
| 9 | Single-family Collection (SF_Col) | Calculates cost, emissions, and fossil fuel use associated with MSW collection from single family sector. | Based on Jaunich et al. (2016). |
| 10 | Multi Family Collection (MF_Col) | Calculates cost, emissions, and fossil fuel use associated with MSW collection from multi-family sector. | Based on Jaunich et al. (2016). |
| 11 | Commercial Collection (COM_Col) | Calculates cost, emissions, and fossil fuel use associated with MSW collection from commercial sector. | Based on Jaunich et al. (2016). |
| 12 | Reprocessing (Reproc) | Calculates emissions, mass flows, and resource use and recovery associated with recycling materials. | Based on data from RTI International (2003). |
| 13 | Transfer Station (TS) | Calculates cost, emissions, and energy use associated with transfer stations. | - |
| 14 | Animal Feed (AF) | Calculates cost, emissions, and energy use associated with conversion of food waste to animal feed and final use of produced feed. | Developed using data from Kim et al. (2011) & Kim and Kim (2010). |
