A Comprehensive Review on the Advancement of Biogas Production Using Leftover Food and Kitchen Waste

Abstract

This review aims to get detailed information about biological reactions in biogas production and the Pressure Swing Adsorption (PSA) approach for biogas upgrading system based on biogas system installed at Rewa Engineering College, Rewa, Madhya Pradesh. The first part of this paper is the pretreatment of microbes, fungal reactions, enzymatic reactions, and metabolic engineering methods. The second part of this paper presents the up-gradation of biogas and their reaction with the PSA technique. The impacts of advancement of biogas production and their potential in advance improving the biogas industry are widely scrutinized. Methane (CH4) (50–65%) in biogas obtained from biogas digester also consists of ammonia (NH3), hydrogen (H2), hydrogen sulfide (H2S) (1–2%), nitrogen (N2) and oxygen (O2) (1–2%), and carbon dioxide (CO2) (25–40%).
