Bio-hydrogen and bio-methane potential analysis for production of bio-hythane using various agricultural residues

The present study targeted towards the feasibility of various agricultural residues for bio-hythane production by anaerobic digestion (AD) process without pre-treatment. Biochemical methane potential (BMP) analysis was carried out for mixed fruit waste (MFW), mixed vegetable waste (MVW), sugarcane bagasse (SB), rice husk (RH), and wheat straw (WS). The analysis of gas was carried out in gas chromatography with a thermal conductivity detector (GC-TCD). The BMP test results in the study for SB, MFW, and MVW reveal that the average percentage value of bio-hythane production was 53.64%, 43.54%, and 40.92% and that of RH and WS was 16.74% and 29.75%, respectively. The result also shows that agricultural biomass, such as WS and RH produces less % of bio-hythane due to the presence of lignocellulosic components. The main contribution of this study is to highlight the bio-hythane potential with reference to the bio-methane and bio-hydrogen productions from the agricultural residues.
