Abstract In the coming decades, humanity will be faced with challenge of feeding 10 billion people and managing large quantities solid waste. These issues can mitigated through development sustainable fertilizers derived from electrochemically treated waste activated sludge (EWAS) while promoting a nitrogen circular economy. This study investigates chemistry novel to determine their soil dynamics. Untreated (WAS) EWAS were applied agricultural potting mix, resulting aqueous samples analyzed nitrogen, phosphorous, carbon adsorption release behaviors. Commercial inorganic natural utilized for comparison. X‐ray absorption near‐edge structure (XANES) spectroscopy was performed characterize phosphorus speciation in phases fertilizers. Results indicated that WAS released less total into solution than other treatments due organoclay complexation biomolecules differences solubility species. Samples containing higher percentage organic deformation matter by alkaline electrolysis process. The increased electrochemical Solid‐phase characterized XANES analysis as struvite, which is finding important implications P management waste‐based experimental findings suggest fertilizing could result reduced runoff improved health facilitating domestic fertilizer production.
