Abstract

This study introduces an innovative approach, addressing dual environmental challenges of water treatment and sustainable bioenergy generation. We have synthesized a sustainable biogenic agal-bivalve shells-based composite (CAL-GRABC) for phosphate recovery from aqueous solutions and subsequent biogas production. The findings revealed that the sorption process of PO₄³⁻ onto CAL-GRABC was pH-dependent with 94.12% removal efficiency under optimized pH ∼4.1. Meanwhile, kinetic studies indicated that the adsorption process conformed closely to PSORE model, while isotherm data were well-correlated with the Langmuir assumption, demonstrating a maximum loading capacity of 333.33 mg g⁻¹. Furthermore, the PO₄³⁻ adsorption process was endothermic. Interestingly, the used sorbent was managed particularly for biogas production resulting in a measured yields of 267 mL-CH₄ gVS^-1, which is 2.2 times the control. To sum up, this research highlights the dual functionality of the developed material, as a promising candidate for wastewater remediation and renewable energy production.

期刊介绍： Biomass & Bioenergy is an international journal publishing original research papers and short communications, review articles and case studies on biological resources, chemical and biological processes, and biomass products for new renewable sources of energy and materials. The scope of the journal extends to the environmental, management and economic aspects of biomass and bioenergy. Key areas covered by the journal: • Biomass: sources, energy crop production processes, genetic improvements, composition. Please note that research on these biomass subjects must be linked directly to bioenergy generation. • Biological Residues: residues/rests from agricultural production, forestry and plantations (palm, sugar etc), processing industries, and municipal sources (MSW). Papers on the use of biomass residues through innovative processes/technological novelty and/or consideration of feedstock/system sustainability (or unsustainability) are welcomed. However waste treatment processes and pollution control or mitigation which are only tangentially related to bioenergy are not in the scope of the journal, as they are more suited to publications in the environmental arena. Papers that describe conventional waste streams (ie well described in existing literature) that do not empirically address ''new'' added value from the process are not suitable for submission to the journal. • Bioenergy Processes: fermentations, thermochemical conversions, liquid and gaseous fuels, and petrochemical substitutes • Bioenergy Utilization: direct combustion, gasification, electricity production, chemical processes, and by-product remediation • Biomass and the Environment: carbon cycle, the net energy efficiency of bioenergy systems, assessment of sustainability, and biodiversity issues.
