Published: March 16, 2025

The efficient resource utilization of livestock manure has received extensive attention worldwide at present, and the related technology been continuously improved, while potential for in terms fertilizer energy is not yet clear. In order to more accurately assess fertilizing energizing manure, this study took Liaoning Province, a large poultry farming province China, as an example. Based on statistical data field research, assessed based calculating amount resources Province 2023 by applying method excretion coefficients other methods. results show that (1) total was 104.41 × 106 t; (2) amounts organic matter (OM), nitrogen (N), phosphorus (P), potassium (K) could be converted into were 18.86 10⁶ t, 2.03 3.05 2.26 respectively, which sufficient replace chemical application Province; (3) energization 3826.73 104 t standard coal or 1950.61 107 m3 biogas, respectively. can provide reference basis preliminary estimation China even world, great significance global reduction dependence fertilizers, optimization structure, maintenance ecological balance. This also help promote improvement policies achieve high efficiency manure.

Advances in Hydrothermal Carbonization for Biomass Wastewater Valorization: Optimizing Nitrogen and Phosphorus Nutrient Management to Enhance Agricultural and Ecological Outcomes

Water, Journal Year: 2025, Volume and Issue: 17(6), P. 800 - 800

Published: March 11, 2025

This study presents a novel approach that integrates hydrothermal carbonization (HTC) technology with circular economy principles to optimize the management of nitrogen and phosphorus in agricultural wastewater. Given increasing global resource scarcity continuous ecological degradation, valorization biomass wastewater has become critical pathway for promotion sustainable development. Biomass wastewater, which contains crop residues, forestry leftovers, food processing byproducts, long been regarded as useless waste. However, this abundant organic matter possesses significant renewable energy potential. The can significantly reduce environmental pollution. Through optimization HTC process parameters, we achieved an improvement quality yield carbonized products, facilitating efficient recycling utilization resources. research demonstrates transform into valuable biofertilizers, energy, feed, while simultaneously reducing reliance on fossil fuels, decreasing greenhouse gas emissions, mitigating impact activities. paper provides comprehensive exploration application ecosystems, highlighting its beneficial role management, efficiency, pollution reduction. findings suggest holds potential optimizing treatment, promoting recycling, advancing Furthermore, offers theoretical support practical guidance implementation is paramount importance fostering economic development achieving agriculture.

From effluent to fertilizer: Phosphorus recovery and reuse using granulated iron-oxyhydroxide-montmorillonite composites

The Science of The Total Environment, Journal Year: 2025, Volume and Issue: 981, P. 179613 - 179613

Published: May 9, 2025

Recovering phosphorus (P) from wastewater offers a sustainable solution to managing the anthropogenic P cycle by reducing water pollution and enhancing its use efficiency in agriculture. This study developed recovery platform using montmorillonite‑iron-oxyhydroxide composites (FeOx-MMT) granulated with polycation. The adsorption properties of granules were compared commercially available ferric hydroxide (GFH) powdered FeOx-MMT. Then, spent material (P-loaded FeOx-MMT granules) was tested as P-fertilizer comparison triple-super-phosphate, commercial fertilizer. Batch tests showed that GFH had higher maximum capacity than (10 mg∙P∙g-1 vs 3.6 mg∙P∙g-1), yet this trend is reversed when normalized iron content (32.4 mg∙P∙g-Fe-1 61 mg∙P∙g-Fe-1). In addition, significantly faster GFH. terms desorption, ability Consequently, column experiments real secondary effluent these trends translated overall removal efficiencies granules: specifically adsorbed phosphate ions while leaving other anions like sulfate, nitrate, chloride solution. Positively charged such Ca2+, Mg2+ NH4+, also removed result high volumes concentrations below 0.1 ppm (regulation limit), loaded essential cations. bioavailability soil then funnel tomato-pot experiments. results suggest released manner can support growth agricultural crops. approach supports management, preserving resources, pollution, promoting food security ecological economic health.

Synthesis of Lanthanum-Modified Natural Magnetite: Characterization and Valorization for Phosphorus Recovery from Aqueous Solutions

Materials, Journal Year: 2025, Volume and Issue: 18(10), P. 2283 - 2283

Published: May 14, 2025

In this research work, a natural sample from an Omani magnetite (MG) deposit was used for the synthesis of decorated with ferrihydrite (MG-Fh), and two lanthanum (La)-modified materials at mass percentages 5% (MG-Fh-La-5) 15% (MG-Fh-La-15). These were first characterized using various analytical techniques. Then, their phosphorus (P) recovery efficacy aqueous solutions studied in batch mode under wide range experimental conditions. The characterization results show that compared to raw feedstock, MG-Fh, MG-Fh-La-5, especially MG-Fh-La-15 have improved structural, textural, surface chemistry properties. Adsorption tests indicate due deposition high contents oxides on its surface, MG-La-15 exhibited large P uptake capacity (34.5 mg g−1), which is significantly superior those determined MG-La-5 (24.3 MG-Fh (12.4 engineered published literature. Moreover, these retain interesting ability recover real wastewater highest adsorbed 27.3 g−1, observed MG-La-15. seems involve both physical chemical mechanisms, including electrostatic interactions complexation. This work shows La-modified can be considered promising eco-friendly material liquid effluents.
