In both energy source configurations, the GHG emissions were primarily driven by the sludge pasteurization, fugitive emissions from effluent, NCS, and the EC unit. The relative GHG contributions varied across units, but trends were relatively consistent between photovoltaic/gridtied configurations: median contributions to life cycle GHG emissions were highest for fugitive emissions from effluent (33%/23%), followed by NCS (31%/22%), sludge pasteurization (22%/32%), and EC (2%/11%; Figure ). Direct emissions can be attributed to fugitive methane leaving the system as dissolved methane in the effluent and residual methane from biogas combustion in the sludge pasteurization unit. The O&M emissions are primarily attributed to the production of the consumables in the sludge pasteurization (specifically, LPG) and the chemically driven NCS units (including zeolite, GAC, NaCl, and NaOH). In the grid-tied configuration, the emissions from electricity consumption are predominantly from the sludge pasteurization unit (13.4 [12.2 -14.6] kg CO2-eq•cap -1 •yr -1 ) and EC unit (7.5 [6.8 -8.1] kg CO2-eq•cap -1 •yr -1 ). When low GHG energy sources are used (including with the photovoltaic configuration), there are tangible emissions benefits from selecting electrically driven treatment processes in NSS technologies. Beyond disinfection, the electrification of nutrient removal also has the potential to reduce costs and GHG emissions. It is also important to note that the foundation, frontend, pretreatment, and foundation had negligible impact on the overall costs and emissions of the NEWgenerator. Sensitivity analysis was used to determine the Spearman's rank-order correlation coefficient of assumptions and parameters in the analysis to determine which had the greatest influence on the uncertainty in cost and GHG emissions of the NEWgenerator (Figures and). The per capita cost was highly sensitive to sludge moisture content with a Spearman's rank-order correlation coefficient of 0.58/0.58 for photovoltaic/grid-tied configurations, respectively. This was followed by urine excretion (0.37/0.36), fecal excretion (0.38/0.38), LPG price (0.33/0.33), and labor wages (0.15/0.14). The sludge moisture content directly relates to the amount of heat (and therefore volume and cost of fuel) needed to dry and pasteurize the sludge from its native water content.
