Effective management of food waste (FW) is essential for achieving energy self-sufficiency and carbon neutrality in treatment plants (FWTPs). Developing a multitandem efficient FW process crucial performing more recovery at on-site plants. In this study, cascading was developed to treat from generation complete disposal. Compared with the unpretreated (UP-FW), enzymolysis exhibited higher hydrolysis efficiencies FW. Specifically, concentrations glucose, chemical oxygen demand, total organic increased by 259.42%, 49.31%, 33.08%, respectively. The pretreated considerable hydrogen yield 35.81 ± 1.47 mL/g-VS, roughly double that raw used as substrate, which also accompanied 26.52% 19.10% increases ethanol acetate production, recyclable catalyst (FRB800) pyrolyzed fermentation residue showed superior Orange G (OG) removal efficiency better anti-interference ability actual water body. OG could be completely removed within 30 min, dominated singlet oxygen, nonradical pathways, diverse active sites on FRB800. This synchronizes resources degradation pollutants. Overall, these findings indicate an alternative approach disposal possesses significant engineering value broad application prospects FWTPs.
