Table shows the reduction in GWP based on incremental renewable energy share. It was found that on incrementing the renewable energy share by 25%, 50%, 75%, 100% for all the five scenarios, the GWP reduced by 23%, 47%, 71%, and 94 -95%, respectively. Usage of renewable energy not only aids in enhancing the environmental performance of the nutrient recovery, but also helps in achieving self-sustainability in agriculture sector. The conventional STP process energized by 75% renewable energy could reduce 71% in GWP. The highest reduction in GWP (96%) was seen for MFC when 100% renewable energy was used to drive it.
