| Περίληψη: | The accumulation of heavy metals restricts the safe agricultural utilization of pig manure. Co-pyrolysis with organic additives offers a promising strategy to overcome the physicochemical defects of manure-derived biochar and enhance metal sequestration. This study investigated the co-pyrolysis of pig manure with distinct solid wastes including food residue, tea stems, and spent coffee grounds at 450-750 °C to elucidate heavy metal transformation mechanisms. Results demonstrated highly efficient immobilization for Cu, Cr, and Ni; specifically, in the tea stem co-pyrolysis biochar at 750 °C, the residual fractions of Cr and Ni reached 87.15% and 80.55%, respectively. Supported by X-ray diffraction (XRD) and Fourier transform infrared (FTIR) spectroscopy, this stabilization is driven by a dual pathway: direct precipitation into stable mineral phases such as Cu (Copyright © 2026 Elsevier B.V.
