Highlights Co-pyrolysis of magnesite with food waste generated MgO hybrid biochar composite. MgO hybrid biochar showed a high phosphorus recovery capacity (523.9 mg/g). Phosphorus recovery was controlled by MgHPO4 formation and electrostatic attraction. MgO hybrid biochar recovered > 98% of P from solution and bio-liquid wastewater. Recovered phosphorus is a slow-release fertilizer available for agriculture use.
