About
WANIRED is a membrane-free electrochemical reactor that reduces nitrates from wastewater into fertiliser-grade ammonia, helping to mitigate both eutrophication and the environmental toll of conventional ammonia production. Designed for decentralised deployment, including in remote or off-grid areas, it uses low-cost, precious-metal-free electrodes and integrates with renewable energy systems. Its continuous flow-through design enables scalable, carbon-free ammonia recovery while treating agricultural run-off, offering a dual solution for water pollution and sustainable fertiliser production

Maria Alvarado
Maria Isabel Alvarado is a PhD student in Applied Physics at KTH Royal Institute of Technology, with a background in materials engineering from Universidad de Concepción. Her research focuses on sustainable water treatment and resource recovery. She has contributed to the Mistra TerraClean project, addressing the removal of PFAS and active pharmaceutical ingredients from wastewater, and to the EU-funded INSPIRE project on microplastic degradation. Currently, she is developing methods to produce green ammonia from nitrate-containing wastewater, advancing circular and sustainable solutions that address both eutrophication and CO₂ contamination challenges.
