Synthesis of Bi-Functional Biochar Utilizing Incinerated Sewage Sludge Ash and Biomass: Improved Nutrient Release and Heavy Metal Adsorption Efficiency

Опубликована: Янв. 1, 2025

Phosphorus (P) is vital for plant growth and abundantly found in incinerated sewage sludge ash (ISSA). However, utilizing this P-rich ISSA efficiently as fertilizer remains a key challenge. This study first successfully synthesized bi-functional biochar-based using acid-extracted shrimp shell through pyrolysis. We systematically examined how impregnation methods, pyrolysis temperatures, biomass types influenced available phosphorus (AP) release, with further optimization Cu(II) adsorption performance mechanism. AP release results indicated that the pre-pyrolysis impregnated biochar prepared at 350 °C (Im-SS350-pre) had maximum (51.68 mg P/g). demonstrated Im-SS350-pre achieved capacity of 66.86 mg/g, due to its highly effective reactive sites. was three times high produced without (25.08 mg/g). For XRD analysis confirmed acid leaching broke metal-P bonds, releasing Ca‒P Mg‒P, while promoted formation phosphate concentration. adsorption, FTIR, XRD, XPS analyses identified mechanisms such coordination, co-precipitation, functional group complexation, Cu‒π interactions. highlights dual functionality providing promising approach recovery copper remediation biomass.

Enhancing phosphorus recovery from poultry litter ash through microwave-assisted thermochemical treatment for improving its solubility

Journal of Environmental Management, Год журнала: 2025, Номер 379, С. 124802 - 124802

Опубликована: Март 9, 2025

This study explores for the first time P recovery from poultry litter ash (PLA) using microwave-assisted thermochemical treatment, aiming to improve its bioavailability utilization as a fertilizer. PLA samples, originating laying hens' manure incineration, were subjected microwave treatment with addition of sodium bicarbonate, and their physical-chemical characteristics analyzed X-ray fluorescence (XRF), diffraction (XRD), scanning electron microscopy energy dispersive spectroscopy (SEM-EDS). The results indicate that led formation NaCaPO4 crystals, significant increase in solubility post-treatment, which is crucial plant uptake. Moreover, increasing amorphous content decrease because atoms tend diffuse within silica network. However, this case, interesting glass materials promising optical properties may be obtained. provides novel approach valorizing biowaste contributes sustainable phosphorus management practices.
