Title : Role of additional nutrients and intermediate temperature on methane generation from anaerobic digestion of agricultural waste: Feasibility & Fertilizer recovery
Abstract:
The rise in demand for organisms pulled in by anaerobic digestion could be due to the simultaneous digestion of many substrates. The impact of supplements on the co-digestion of growth substrates was investigated in this study. In three phases, 37 °C, 40 °C, and 50 °C, an extra improvement plan that anticipates a critical occupancy in anaerobic digestion was used. As a result of the changes, biogas output climbed to 1.38 times that of the control at 37 °C. Furthermore, as a result of 40 °C without additives, the excellent usage of this newly discovered mid-temperature considerably influenced an innovative philosophy (56 percent of VS end and 8.4 L-biogas). Biogas output surpassed 11.3 L with supplements during anaerobic co-digestion at 50 °C, and mL-CH4/g-VS was 1.24 times that of the system without any extra improvement. The results reveal that at each temperature, the improved course of action promotes co-digestion. The most generally utilized temperature on the advanced scale was 37 °C, which had the biggest influence on the utilization of improvements during the anaerobic process. Sludge was recovered at a rate of 0.09 m3 sludge/m3 substrate from the digester, while water was recovered at a rate of 0.86 m3 sludge/m3 substrate from the digester. The processed sludge may be utilized as compost, and the water can be used to water plants. The time it took to recoup the investment was found to be 3.77 years. As a result, it may be inferred that the current research might soon be recognized as a potential green solution for trash management across the world.
