This study aimed to evaluate and optimize trickle bed reactor (TBR) performance for biological biogas upgrading at different gas loading rates (10-35 m3/m3d) by adjusting H2 flow (H2/CO2 ratio 4-3.7) and utilizing various packing materials. The three TBR reactors operated at thermophilic conditions (50○C) with different packing materials under same gas loading rate. Obtained results indicated that optimal performance was achieved at a gas loading rate of 14.3 m3/m3d and H2/CO2 ratio of 3.7, with average CH4 concentrations in the effluent gas from 90.8 % to 91.5 %, regardless of the packing material employed. Increasing the gas loading rate resulted in decreased CH4 content (<90 %), indicating limited treatment capacity at higher loading rates. The studied packing materials had a slight impact on reactor performance indicating that the shape of the making material has a greater influence of the reactor performance. Microbial communities analyses revealed dominance of hydrogenotrophic methanogens (Methanobacterium, Methanothermobacter, and Methanoculleus). This study highlights the importance of optimizing the H2/CO2 and considering packing materials for TBR performance.

Horticultural food waste can be recovered to produce high-value products. Appropriate green solvents and a selection of cleaner production could unlock waste into useful resources for human health. This will significantly reduce greenhouse gas emissions, and CO2 production, and create economic opportunities to contribute to food security.
