Phosphorous recovery from laundry effluents as Struvite and Struvite-K: A batch crystallization study based on a three-factor central composite design

open access: yesNext Materials
The recovery of phosphate resources from laundry wastewater and the production process in the forms of Struvite and Struvite-K were investigated through a batch crystallization experiment using a magnetic stirrer at stirring rates ranging from 100 to 250

Milky urine and struvite crystals [PDF]

open access: yesKidney International, 2015
A 66-year-old man was referred to the nephrologist because of recurrent episodes of afebrile low back pain, voiding-associated pain, and milky urine. Past history was positive for urolithiasis due to calcium oxalate stones, managed with hydrochlorothiazide 12.5 mg/day for the last 3 years.

Molecular structure and nickel‐binding capacity of Proteus mirabilis UreE

open access: yesActa Crystallographica Section D, Volume 82, Issue 4, Page 348-357, April 2026.
This study presents a 2.0 Å resolution crystal structure and determined the nickel‐binding capacity of the P. mirabilis nickel chaperone UreE. UreE is essential for the delivery of nickel to the metalloenzyme urease, which is key for the ability of P. mirabilis to cause urinary‐tract infections.UreE is a nickel chaperone that is required for the safe ...

Differences in Recycled Amendment Phosphorus Solubility and Transport When Interfaced to Soils of Dissimilar Characteristics

open access: yesSoil Use and Management, Volume 42, Issue 2, April‐June 2026.
ABSTRACT Increasing phosphorus (P) fertilizer use efficiency from bio‐based waste products (i.e., recycled amendments) requires promoting a larger proportion of bioavailable P in soil for plant uptake. Therefore, this study aimed to elucidate how recycled amendment P solubility and movement vary when interfaced with soils of contrasting characteristics.

ZeroWasteWater: short-cycling of wastewater resources for sustainable cities of the future [PDF]

open access: yes, 2010
Sewage treatment relies mainly on conventional activated sludge (CAS) systems, reaching sufficiently low pollutant effluent levels. Yet, CAS has a low cost-effectiveness and recovery potential and a high electricity demand and environmental footprint. By

Rice response as affected by various fertilizer‐P sources under contrasting irrigation methods

open access: yesAgrosystems, Geosciences &Environment, Volume 9, Issue 1, March 2026.
Abstract Alternative fertilizer‐phosphorus (P) sources created by recycling excess nutrients from waste sources, such as struvite (MgNH4PO4·6H2O), require further research to determine their niche in agriculture and potential environmental implications.
