Mesophilic anaerobic co-digestion of sunflower oilseed processing waste with yeast residues inoculum
Year: 2025
Type: article
Abstract: ABSTRACT This study investigates the lab-scale mesophilic anaerobic digestion of sunflower oilseed processing waste (SOPW) with yeast residue inoculum (YRI) in batch mode, focusing on the impact of mixture composition and inoculum-to-substrate ratio (ISR) on process efficiency. Sample, containing 43.7 g VS ·L –1 with ISR of 0.276, achieved the highest specific methane yield of 102.9 mL CH4 ·g VS −1 , representing 81.6% of the YRI-control. Thermogravimetric analysis demonstrated that anaerobically digested samples contained less thermally stable components compared to raw substrates. Results highlight the critical role of SOPW composition in optimizing biomethane production and underscore the importance of managing ISR for the effective AD of SOPW.
