Electrochemically recovered struvite matches conventional fertilizers in soil nutrient supply

Agrosystems, Geosciences &Environment, Volume 9, Issue 1, March 2026.
Abstract Phosphorus (P) is an essential macronutrient for agriculture, yet global reliance on finite phosphorite reserves raises concerns about long‐term food and nutrient security. Struvite (MgNH4PO4·6H2O), a mineral recovered from municipal wastewater, represents a sustainable and circular source of P, but uncertainty remains regarding its nutrient ...

Integrating Anaerobic Digestion With Struvite Production for Enhanced Nutrient Recovery, Pathogen Reduction, and Circularity in Manure Management

Journal of Sustainable Agriculture and Environment
Introduction Anaerobic digestion (AD) is essential for manure management, generating biogas and nutrient‐rich digestate for organic fertilizer. However, improper digestate use can pose environmental risks.

Potential for potassium recovery as K-struvite

, 2016
Crystallization of NH₄-struvite (MgNH₄PO4:6H₂O) pellets has proven to be a successful method of recovering nitrogen and phosphorus from wastewaters. Thus far, little work has been done on potassium recovery since it is not considered a water pollutant, nor do we face potassium shortages. However, potassium is an essential plant macronutrient and we are

Plant and Soil Effects of Alternative Sources of Phosphorus over Three Years of Application

Agronomy
Plant growth and food security depend heavily on phosphorus (P). Recovering and recycling P from animal, municipal, and food waste streams can significantly reduce dependency on traditional mineral P. This is particularly pertinent in the EU regions with

Effects of the Optimised pH and Molar Ratio on Struvite Precipitation in Aqueous System

MATEC Web of Conferences, 2016
Struvite (MgNH4PO4.6H2O) is one of phosphate minerals, commonly forms into aqueous solutions. It can be precipitated as mineral deposits for optimization of phosphate recovery based on the pH optimum, molar ratio and temperature levels.
