Formation of struvite crystals in a simulated food waste aerobic composting process

Bench-scale treatments with three mixtures of Mg and P salts, including K3PO4+MgSO4, K2HPO4+MgSO4, and KH2PO4+MgSO4 as additives in a simulated food waste aerobic composting process, were conducted to test the magnesium ammonium phosphate(MAP) formation, and the compost products were analyzed by X-ray diffraction(XRD), Scanning electron microscopy(SEM), and Energy dispersive X-ray spectroscopy(EDS) analyses. The comparison results between XRD, …
