This Excel-based life cycle inventory (LCI) model develops LCI data for management of wasted food via anaerobic digestion (AD), windrow and aerated static pile (ASP) composting, landfilling and incineration. The inventory model is run for the following scenario options: >AD biogas fate: flare, combined heat and power (CHP) and renewable natural gas (RNG) >Landfill gas fate: flare, electric engine, and RNG >Compost method: windrow and ASP >Incineration technology: Grate furnace - mass burn >Digestate management: compost + land application, land application of whole digestate and digestate landfilling >Land application modeling is limited to avoided fertilizer credits and carbon sequestration benefit. Estimating emissions associated with land application is beyond the scope of this model. Implicitly, emissions associated with compost and digestate are assumed to be equivalent to those from avoided synthetic fertilizer, leading to a net zero change in impact when changing nutrient sources.

The output is stored in the 'LCI' tab which can be exported into a csv or other text-based file. Definitions for the field names in the LCI sheet is included in the 'LCI Key' tab.
