Phosphogypsum (PG) is the largest by-product of phosphate industry. Nearly 300 M tons PG are annually discarded, which 58% dry stacked. The exposure stacks to rainwater and processed waters moisture creates hydraulic pressure, generating acidic leachates into nearby aquifer systems. Because its elevated levels sulfates, phosphorus (P) heavy metals, water leachate can negatively affect surrounding environments. This work investigates effect activity on leaching, by studying different PG:Water ratios leaching process, followed anaerobic bioremediation through biological sulfate removal (BSRA). later involves using sulfate-reducing bacteria consortium within an bioreactor, allowing a simultaneous monitoring leachate's biochemical changes, impurities removal, microbial community dynamics results determined highest sulfates from with ratio 1:200 (w:v). Subsequently, treatment exhibited efficient (79%), P (99%) chemical oxygen demand (93%), substantial decline in metal concentrations (Cd, As Al 99%, Zn 70%) leachate. Moreover, acidity was also neutralized SRA process increasing pH 4 7.52. Furthermore, unveiled significant correlation between changes co-existence specific phyla, including Desulfobacterota, Firmicutes, Proteobacteria, eco-friendly

Abstract While it remains debated if mineral deposits mined for phosphorus fertilizer are running out, insecurity is an emerging global issue. We explore how linked to the current linear economy (LPE) and historic implications. The problems multifold: there geopolitical concerns over held only by a few nations, sharply rising costs of fertilizers, heavy metal contaminants affecting soil food, problematic mining wastes, environmental degradation caused inefficiencies. Here we argue that new can resolve these problems. Transitioning sustainable use demands circular (CPE). A CPE supports several Sustainable Development Goals enables greater autonomy. illustrate with case studies outline opportunities change. will feature recovery facilities, waste valorisation technologies, improved formulations customized target crops crop systems. highlight examples rapidly advancing essential agriculture.
