Biogas residue biochar integrated with phosphate from its ash for the effective recovery of nutrients from piggery biogas slurry
| • | For the first time, phosphorus in BRC was used as the phosphorus source for MAP treatment of biogas slurry. |
| • | Nitrogen and phosphorus were mainly recovered by MAP precipitation and functional group bonding of functionalized BRC. |
| • | N-rich biogas slurry was treated with P-rich biogas residue to produce biochar-based slow-release N-P fertilizer. |
