Studies on Improving Biogas Production Rate and Methane using silk worm larval litter and agricultural wastes

Abstract

newline The use of agricultural, dairy waste, food, and animal waste to generate biogas, which is used as newlinean alternative energy source. Crop cultivation is the primary occupation of the people in most newlinedeveloping countries such as India and China, and crop residues left after harvesting are posing a newlinebig problem to the environment. Since the agricultural wastes have lignin hemicellulose, and newlinecellulose, these biomasses are not economically utilized and are either disposed of in the open newlineareas or burned, creating significant health problems and environmental contamination. newlineIn the current research, lignocellulosic biomasses are evaluated by sub kecking to anaerobic newlinedigestion to produce biogas and conducted kinetic studies on processed biogas. Silkworm larval newlinelitter, cow dung, cattle urine, cashew fruit, and Cyperus rotundus waste are becoming more newlinecompatible with energy production. Its abundant and low cost make it ideal for biogas processing. newlineThe Characterization of selected substrates is done and noticed that the selected biomass is rich in newlinecarbon and lignin content. The effect of silkworm larval litter, cow dung, cattle urine, cashew fruit, newlineand Cyperus rotundus screening on biogas yield was studied under mesophilic (35°C) conditions. newlineFurthermore, the research looked at the biogas yield and methane production of various blends of newlinesilkworm larval litter, cattle urine, cashew fruit, and Cyperus rotundus. From the different samples, newlinethe biogas has been obtained and biogas properties are evaluated. Based on the thermal properties newlinethe best sample of biogas has been implemented in the diesel engine to check the engine newlineperformance The anaerobic co-digestion of 45% Silkworm larval litter + 15% cashew nut fruit newline+10% dairy waste+30% water produced a high biogas production (9.21m3) and methane yield of newline74.58 percent. The higher methane content of the above-mentioned sample greatly enhances and newlinemakes it more competitive than other blends. The higher methane content influences the higher newlinecalorific value (37.98Mj/kg) of bio
