From waste to catalyst: A “waste−treats−waste” strategy using vivianite for simultaneous phosphorus recovery and sulfadiazine degradation

Key Points

• Enhanced phosphorus recovery observed alongside significant sulfadiazine degradation, showcasing a dual benefit.
• The analysis revealed a phosphorus recovery rate exceeding 90% under optimal conditions.
• Employing vivianite as a catalyst provided effective waste treatment methods for both phosphorus and sulfadiazine.
• These findings support a sustainable, circular economy model for waste management practices.
