Beyond unit costs and GHG intensity of grid electricity across countries, assumptions about diet (consumption of vegetal protein, animal protein, total caloric intake) and caloric intake also influenced the performance of both configurations due to changes in influent COD and nutrients and subsequent changes in O&M (Figures and). Given the differences in costs and GHG emissions between the general case and country-specific scenarios (Figure ), it is clear contextual parameters can influence the economic and environmental sustainability of the NEWgenerator. Locality-specific manufacturing assumptions could be revisited in future work to support more in-depth, community-specific evaluations. For example, if it is known the photovoltaic panels will be sourced from China (which accounts for 62% of total photovoltaic panel production worldwide ), global average emissions factors could be replaced with values representative of typical production practices in China. Similarly, community-specific diets, material pricing, consumables pricing (and their associated uncertainties) can be considered when known. Ultimately, the inclusion of more detailed contextual parameters can provide more accurate results in a given deployment context and should be pursued when performing community-specific evaluations.
