title: Electrochemical ammonia recovery and co-production of chemicals from manure wastewater

description: Livestock manure wastewater, containing high level of ammonia, is a major
 source of water contamination, posing serious threats to aquatic
 ecosystems. Because ammonia is an important nitrogen fertilizer,
 efficiently recovering ammonia from manure wastewater would have multiple
 sustainability gains from both the pollution control and the resource
 recovery perspectives. Here, we develop an electrochemical strategy to
 achieve this goal by using an ion-selective potassium nickel
 hexacyanoferrate (KNiHCF) electrode as a mediator. The KNiHCF electrode
 spontaneously oxidizes organic matter and uptakes ammonium ions (NH₄⁺) and
 potassium ions (K⁺) in manure wastewater with a nutrient selectivity of
 ~100%. Subsequently, nitrogen- and potassium-rich fertilizers are produced
 alongside the electrosynthesis of H₂ (green fuel) or H₂O₂ (disinfectant)
 while regenerating the KNiHCF electrode. The preliminary techno-economic
 analysis indicates that the proposed strategy has notable economic
 potential and environmental benefits. This work provides a powerful
 strategy for efficient nutrient (NH₄⁺ and K⁺) recovery and decentralized
 fertilizer and chemical production from manure wastewater, paving the way
 to sustainable agriculture.
