Agricultural dry residues management stretegies and its potential for Biogas Production

Anaerobic digestion reactions can be used to produce biogas from sources of agricultural waste. The ecology has been harmed by fossil fuels, while biogas solves environmental and climate change-related problems. The goals of biorefineries, global warming, nutrient recycling, and greenhouse gas reduction come after the techno-economic study of biogas production. Furthermore, various metabolic reactions, the use of various microbes, filtration, upgrading, and CO ₂ removal from the gas mixture procedures all play a role in the creation of biogas. Agricultural wastes are important sources for the production of biogas. Biogas or bio methane generation relieves the negative impact of fossil fuels and agro wastes. Biogas can be generated from agro-industrial wastes with lignin, cellulose and hemicellulose. An very promising method for handling agricultural waste that reduces pollution and produces energy effectively is anaerobic digestion. Therefore present study was conducted for screening of bio-waste for biogas generation. Resultants in all three digesters gas generation was found in sorghum than wheat straw while coconut shows the least gas generation. Study also found that higher gas production was seen at 21 DAD (day after digestion). The study concluded that agricultural wastes are important sources for the production of biogas. Therefore selection of most cellulosic agricultural plants will be helpful for biogas production and also relieve the negative impact of fossil fuels and agro wastes.
