Notably, although the NEWgenerator has been designed for 100 users, it has been tested with an estimated 100-200 users in the South Africa field trial. Further, we simulated underutilization (down to 50 users; results in SI) and hypothetical increases in system loading in Scenario 1 to characterize the cost and GHG implications of these use cases. Additionally, nutrient recovery, sales, and emission offsets were not considered in the baseline scenario as the current design would require additional treatment units to achieve commercial quality nutrients. However, the potential of recovered nutrients to reduce cost and GHG emissions were evaluated in Scenario 5.
