The deployment of the NEWgenerator in other contexts was simulated by varying assumptions of influent composition, influent loading, electricity grid characteristics, and other contextual factors (e.g., LPG price), but other locality-specific factors (e.g., anal cleansing practices) will also be important to consider if more absolute costs and life cycle GHG emissions are required in specific deployment contexts. The sustainability indicators considered in this study were costs (economic) and life cycle GHG emissions (environmental), but future sustainability analyses may also consider the broader sanitation social-ecological system (S-SES) that define sanitation technology as one component of a larger human-environmental system; 64 additional studies on these aspects are critical for sustained use of NSS technologies. There are significant reductions in per capita cost which can be achieved by increasing the number of users without increasing the system's physical footprint, but the potential of this approach is heavily dependent on whether the system can maintain treatment performance at these higher loadings and would require further laboratory and field testing. Targeted improvements to components (lithium photovoltaic battery, lower cost housing), reduced sludge moisture content and frontend O&M ratio can provide significant cost rand GHG reduction when combined. Further exploration of these alternative components, a low-cost sludge drying method prior to sludge pasteurization, and reducing O&M costs are recommended. The alternative zeolite management scenarios (replacement only and increased zeolite capacity) were more expensive and incurred more life cycle GHG emissions than the baseline design due to increased zeolite consumption and are not recommended. The addition of a HFMC for dissolved methane recovery is theoretically promising, with potential to significantly reduce GHG emissions and increase energy recovery with a modest increase in cost. Thus, the use of a HFMC with the NEWgenerator may be worth exploring experimentally. Resource recovery of nutrients at the current scale of users only had minimal reduction to per capita costs and life cycle GHG impacts through fertilizer offsets, but future work should explore the detailed design of resource recovery systems and mechanisms to improve economic outcomes of recovery at a larger scale of users. Resource recovery systems may target commercial quality fertilizers to enter existing fertilizer markets, but it is also important to note that the recovered resources may provide intangible benefits to the local community such as proximity to and lower costs of locally sourced fertilizers (to replace or supplement synthetic fertilizer products).
