Harnessing Ligno Cellulose and Cellulose Derivative Residues for Sustainable Biomethanation With Effect of Different Transformation in Rsm Optimization

Abstract

Abstract Biogas technology stands out as a viable energy alternative in rural areas, acclaimed for being an exemplary appropriate technology that addresses the fundamental need for fuel. By utilizing discarded and lingo cellulose derivatives such as potato peel waste sourced from vegetable markets, this technology harnesses energy in the form of biogas enriched with a high methane content. The anaerobic bacteria play a pivotal role in converting and peel wastes into biogas through a synergistic process. Crucial considerations for the biomethanation process encompass process parameters like substrate concentration, substrate and cell mass concentration. Simultaneously, kinetic parameters such as maximum specific growth rate, kinetic constant, and ultimate methane yield take precedence in the anaerobic digestion process for efficient biogas production. This study endeavors to explore the anaerobic reactions of potato and potato peel wastes within a semi-batch digester. Variations in substrate concentrations and different substrates significantly impact biogas production, leading to the development of a mathematical interpretation of the biomethanation process. Between 33.16 and 38.68 MJ/Nm3 of biogas is the energy yield obtained from this procedure. Through a meticulous mathematical analysis of experimental data, model equations correlating ultimate methane yield with diverse substrate concentrations and loading have been formulated.
