Biogas is a renewable energy source that can help meet global energy demands while also managing waste and reducing greenhouse gas emissions. It is considered carbon neutral because the carbon in biogas originates from organic matter (feedstock) that absorbed atmospheric CO2 over a relatively short period of time.

This book has been written and compiled to provide the latest information on biogas technology, with the goal of helping readers, researchers, and extension workers understand the processs benefits. It contains fourteen chapters, primarily divided into three major categories: 01. The first category covers the fundamental aspects of the biomethanation process, including ecology, microbiology, biochemistry, and molecular biology. 02. The second category discusses the evolution of the technology in the Indian and global context, from the laboratory to the field. 03. The final category examines the economics of the technology. Experts in the field have contributed to the books chapters.

The Annexures provide additional useful information, including a model bankable scheme for biogas commercialization, frequently asked questions about adopting biogas technology, common terminologies in biogas research, a glossary of abbreviations and symbols used in biogas research, and prominent global entities involved in biogas R&D and commercialization.
