Résumé
Separate collection of urine to recover nitrogen and phosphorus has been advocated to
enhance the sustainability of water management and food production. Urine could provide a
renewable source of nitrogen and phosphorus, which are currently extracted from nonrenewable
resources. Urine diversion also has the potential to prevent nutrients from entering water bodies
and to reduce the amount of energy and chemicals needed to treat wastewater. However, urine
diversion would require systems to collect urine, produce urine-derived fertilizers, and to ship
them, all of which have their own environmental impacts. This thesis explores the greenhouse
gas emissions, cumulative energy demand, freshwater use, eutrophication potential, and
acidification potential of systems that recover urine compared to those that do not. It evaluates
the importance of location-specific factors by focusing on three locations, and then by
conducting further sensitivity analysis. This work has been submitted to the journal
Environmental Science & Technology (currently in review).
