Safety and Effectiveness of Struvite from Black Water and Urine as a Phosphorus Fertilizer [PDF]
, 2011 To ensure food supply, phosphorus must be recycled, for which an appealing method is using struvite fertilizer from human excreta. One struvite from black water and another from urine were assessed for safety under Dutch regulations, and for ...

Phosphorus retention and agronomic efficiency of refined manure-based digestate—A review
Frontiers in Sustainable Food Systems, 2022 Digestate, a by-product from anaerobic digestion of organic materials such as animal manure, is considered a suitable plant fertilizer. However, due to its bulkiness and low economic value, it is costly to transport over long distances and store for long

Struvite Precipitation and Phosphorous Removal from Urine Synthetic Solution: Reaction Kinetic Study
Bulletin of Chemical Reaction Engineering & Catalysis, 2015 Phosphorus, like oil, is a non-renewable resource that must be harvested from finite resources in the earth’s crust. An essential element for life, phosphorus is becoming increasingly scarce, contaminated, and difficult to extract.

Morphogenesis and evolution mechanisms of bacterially-induced struvite
Scientific Reports, 2021 Bacteria are able to induce struvite precipitation, and modify struvite morphology, leading to the mineral with various growth habits. However, the relevant work involving the morphogenesis is limited, thereby obstructing our understanding of bacterially
