Abstract

AbstractThe main aim of the present study is to focus on the generation and optimization of methane gas from organic waste by using anaerobic digestion (AD) technique. Anaerobic digestion is a traditional method that is in use for decades. It is the biggest source of renewable energy. It gives an optimal solution to the treatment of organic waste by giving useful byproducts. The byproducts of AD, mainly biogas, are directly used as an energy resource. It can be transformed into any form of energy. The efficiency of the AD process and the amount of gas production fully depend on parameters such as pH, temperature, holding time and recirculation of leachate (Gopal in J King Saud Univ Sci 33, 2021). Recently, a concept of co-digestion came into focus in which two organic wastes are digested together to enhance the efficiency of the digestion process. The results obtained by different researchers proved that co-digestion of two substrates produces a large quantity of biogas than a single substrate. Results obtained by experimental analysis can be optimized by using different types of software like MATLAB, RSM, i.e. Response Surface Methodology and ANN, i.e. Artificial Neural Network.KeywordsAnaerobic digestion (AD)Co-digestionBiogas
