Biogas, a renewable energy source, presents a potential alternative to meet global energy demands while simultaneously managing waste and reducing greenhouse gas emissions. It is considered carbon neutral as the carbon in biogas originates from organic matter, also known as feedstock, which absorbed CO2 from the atmosphere over a relatively brief period of time.

This book has been meticulously curated to provide the latest information on biogas technology. Comprised of fourteen chapters, the content is primarily divided into three key sections: 01. The first section delves into the fundamental aspects of the biomethanation process, including its ecology, microbiology, biochemistry, and molecular biology. 02. The second section offers insights into the evolution of the technology in both the Indian and global contexts, tracing its development from the laboratory to large-scale implementation. 03. The final section focuses on the economics of the technology. Renowned experts in the field have contributed their expertise to ensure the accuracy and relevance of the content.

The book's usefulness is further enhanced by the inclusion of annexes, which provide additional resources such as a model bankable scheme for biogas commercialization, frequently asked questions about adopting biogas technology, a list of common terminologies in biogas research, a glossary of abbreviations and symbols commonly used in biogas research, and an overview of prominent global entities involved in biogas research and development.
