Title : Bio-methane production from anaerobic digestion of agricultural waste with extra nutrients and intermediate temperature: Feasibility and Fertilizer recovery


The rise in demand for organisms pulled in by anaerobic digestion might be due to the simultaneous digestion of many substrates. Supplements' effects on the co-digestion of growth substrates were investigated in this study. In three phases, 37 °C, 40 °C, and 50 °C, an additional improvement plan was utilised, which anticipates a crucial occupancy in anaerobic digestion. As a result of the adjustments, biogas output at 37 °C increased to 1.38 times that of the control. Furthermore, as a result of 40 °C without additives, an innovative philosophy was profoundly influenced by the good utilisation of this newly discovered mid-temperature (56 percent of VS end and 8.4 L-biogas) mL-CH4/g-VS was 1.24 times that of the system without any further improvement during anaerobic co-digestion at 50 °C, and biogas production exceeded 11.3 L with supplements. The findings show that the modified course of action increases co-digestion at each temperature. On the advanced scale, the most commonly used temperature was 37 °C, which had the greatest impact on the use of improvements during the anaerobic process. Sludge was recovered from the digester at a rate of 0.09 m3 sludge/m3 substrate, whereas water was recovered at a rate of 0.86 m3 sludge/m3 substrate. The sludge that has been treated can be used as compost, and the water can be used to water plants. 3.77 years was discovered to be the time it took to repay the investment. As a consequence, it's possible that the present research may be acknowledged as a potential green option for waste management throughout the world in the near future.


Dr. Md Nurul Islam Siddique studied Civil Engineering at the Khulna University of Engineering & Technology, Bangladesh, and graduated as MS in 2012 from University Malaysia Pahang. He then joined the research group of Prof. Zularisam at the Institute of University Malaysia Pahang. He received her Ph.D. degree in 2015 at the same institution. After that, he obtained the position of Assistant Professor at the University Malaysia Pahang. She has published more than 40 research articles in ISI journals.
