Comparative Assessment of Biogas Production Potential of the Most Abundant Agro-residues in Turkey

Recent energy policies promote generations from green resources to meet sustainability criteria. Since Turkey is one of the largest agricultural producers globally, it has great biogas production potential. This study aims evaluate biomethane yields most abundant agro-residues in and assess their potentials for contribution production. Within this scope, sunflower heads, tea residues, cotton stalks, crop residues; wheat, rye, triticale straws were collected different regions Turkey. Anaerobic batch digesters conducted investigate selected feedstock operated 30 days at 37°C. Each setup was triplicates methane productions monitored online. The main route inoculum determined as acetoclastic methanogenesis while Cloacimonetes, Firmicutes, Bacteroidetes composed core bacterial phyla. greatest yield observed with wheat straw followed (164 NmL/gVSinfluent) by head. lowest calculated fed stalks (71 NmL/gVSinfluent). To increase potential anaerobic make more feasible, operational conditions should be optimized physico-chemical biological pre-treatment techniques and/or bioaugmentation applications integrated into systems.
