Abstract

In recent years, there has been considerable attention to renewable energy resources for environmental protection to handle and treat food wastes and organic wastes. Anaerobic digestion is a promising option to manage and treat food and organic wastes. Biogas plants will act as energy suppliers and fertilizers to protect our environment. This paper will give an overview of the research achievements and technologies of biogas plants in recent years. This article mainly focuses on characterization, fabrication, and factors that affect biogas production over the years. The major factors like temperature, hydraulic retention time, pH, and organic loading rate will play major roles in production efficiency. Pretreatment technologies and additives inhibition will promote biogas yield., This paper will review different pretreatments and additives followed. There are several microbes found in nature, and these microbes will directly stimulate the action of a particular enzyme to increase efficiency, which can easily reduce the hydraulic retention time. The presence of microbial cultures and bacterial species such as acetomycetes increased methane generation while lowering COD levels.
