Study of Electrohydrolytic Pretreatment on Lignocellulose Waste Material for Improved Production of Biomethane

Abstract

An anaerobic digestion is well developed technology widely applied for bioenergy production from the sewage sludge, animal manure, agricultural residue, industrial sludge etc. This substrate has high levels of biodegradable organics make it an ideal feedstock for anaerobic digestion. Due to the continuous production in the industrial level, there is a huge accumulation of waste especially in sugar mills; the huge quantity of bagasse as residue was produced. Due to the natural intractable structure of lignocellulose biomass towards microbial or enzymatic deconstruction, pre-treatment is necessary to make the celluloses open to enzymatic hydrolysis for fermentation and anaerobic digestions. In recent years, there has been improved concern in pretreatment of lignocellulose biomass and waste for anaerobic digestion. The several structural and compositional properties of lignocellulosic content render it resistant to biodegradation. Even though there has been an extensive research on the effect of pretreatment, the correlation between the degradability of lignocellulose material, the structural and compositional properties remains unclear and contradictory.
