The aim of this study was to evaluate the performance of the swine waste anaerobic co-digestion - specifically swine hydrolyzate and swine slurry - combined with fruit and vegetable waste for biogas production, and to assess the potential use of the resulting digestate as biofertilizer. In batch tests, methane production was 518.10 \u00b1 7.10 mL g VS-1. According to the modified Gompertz model, the methane production rate was 89.51 \u00b1 1.30 mL g VS-1 day-1, achieving 90 % of the production potential within a digestion time of 9.47 \u00b1 0.12 days. At a constant hydraulic retention time of 20 days, the anaerobic co-digestion semi-continuous test achieved an average biogas composition of 73.22 \u00b1 1.36 % (v\/v) methane and 25.41 \u00b1 0.78 % (v\/v) carbon dioxide. Anaerobic process stability was observed, indicating the potential for the future integration of these wastes into industrial technologies for renewable energy production. Additionally, it complied with legal requirements regarding the agronomic valorization of the digestate.<\/jats:p>","DOI":"10.2139\/ssrn.6223716","type":"posted-content","created":{"date-parts":[[2026,2,12]],"date-time":"2026-02-12T07:39:29Z","timestamp":1770881969000},"source":"Crossref","is-referenced-by-count":0,"title":["Biogas
