Description
Zepeng Wang and seven co-authors present a 2026 paper on recovering phosphorus from wastewater by growing a fertilizer mineral in place. The element is both a pollutant in waterways and a finite farm resource. Struvite crystallization captures it, but standard recipes need bought magnesium salts and alkaline chemicals. The team instead dissolved natural magnesite rock with electric current: the current freed magnesium ions while the cathode made its surroundings alkaline, so the mineral could form.
Under tuned settings, about fifty-eight percent of the phosphorus was recovered and the solid reached roughly sixty-three percent purity by their estimate. They note some nitrogen loss may be ammonia escaping near the cathode rather than entering the mineral. Imaging and diffraction confirmed struvite in the product. The authors pitch the reagent-saving route for greener recycling of the element.
