AWMC Seminar Program: Microbial Electrochemical Systems for nutrient recovery from source-separated urine

Microbial Electrochemical Systems for nutrient recovery from source-separated urine - Juliette Monetti (PhD student, AWMC)

Current fertiliser production relies on the use of non-renewable energy and finite material resources. In addition, nutrients consumed by humans are all excreted via urine and faeces, which end up in wastewater streams. Most of the nutrients present in wastewater come from urine. Source-separation could allow for the recovery of these nutrients to be used as fertilisers. To date, the most promising nutrient recovery process from urine is struvite precipitation which only recovers phosphorus (P), leaving most of the nitrogen (N) in the liquid phase.

Recently, source-separated urine as a substrate for Microbial Electrochemical Technologies (METs) has gained interest due to urine’s promising properties. A novel MET for the recovery of macro- and micro-nutrients from source-separated urine will be described. This seminar will present the research objectives and plan aiming to bring this technology and its micropollutant-free concentrate fertiliser closer to implementation.
