The National Science Foundation Engineering Research Center for Advancing Sustainable and Distributed Fertilizer Production (CASFER) is a partnership among five US-based universities that are developing low-energy technologies to convert organic waste into decarbonised fertiliser products. The technology utilises electrolysis to valorise sludge, enabling the capture of nutrient-rich organic biosolids together with nitrogen- and phosphorus-based fertilisers in circular economies. Further trials have demonstrated the potential for electrolysis to augment digestion. A New Zealand based start-up is working with CASFER to rapidly commercialise the technology and has identified opportunities for world-first implementation. This presentaiton will demonstrate the use of electrolysis as a low energy technology to maximise the nutrient, organic carbon and energy value of wastewater sludges, while addressing emerging contaminants and maximising existing infrastructure. The presentation will highlight the power of collaboration between research institutions and industrial and engineering partners to fast-track real-world solutions.
