Review of Anaerobic Biotechnology for Bioenergy Production, November 30, 2010
This review is from: Anaerobic Biotechnology for Bioenergy Production: Principles and Applications (Hardcover)
Anaerobic biotechnology is emerging as one of the most important sources of renewable energy available. The basic technology, anaerobic digestion or AD, is well proven and produces methane gas as a clean energy source through the activity of a complex group of microorganisms in the absence of oxygen. It is an extraordinarily versatile technology, capable of producing energy from a broad combination of wet or dry organic materials including wastes such as sewage sludge, animal manures, and municipal solid wastes, as well as dedicated biomass crops. As an energy producing process, AD also makes a significant contribution to environmental protection by isolating and stabilizing polluting sources of organic wastes. In addition, by capturing otherwise uncontained sources of methane gas, which has a global warming potential 23 times greater than equivalent amounts of carbon dioxide, it also significantly reduces climate change effects. Anaerobic processes, by not requiring supplemental oxygen, also offer significant savings in energy and operational costs compared to the more commonly used aerobic systems.
Despite these overwhelming benefits, anaerobic digestion has to date remained a Cinderella in the renewable energy picture, taking a back seat in interest and investment to such widely touted (and often controversial) renewable energy sources as ethanol, biodiesel and algae. Perhaps it is because producing energy out of materials such as manures, sludges and garbage is unappetizing, even though it makes far more financial and environmental sense than growing foods such as corn to produce energy.
This excellent book by Dr. Samir Khanal -"Anaerobic Biotechnology for Bioenergy Production" should change these perceptions once economic interests with a focus on renewable energy begin to study it. It is an important and game-changing document in my opinion.
It strikes a useful balance, particularly in the overview chapters, between mind-numbing technical detail (which is available in the book for specialists), and technical oversimplification. A feature which also impressed me about this book is how clearly and concisely it is written. It will not put the beginning student, the experienced technical specialist or the non-technical overview seeker immediately to sleep as many books of this genre tend to do. It is obvious that Dr. Khanal made a concerted effort to teach and educate with a broad audience in mind. As such, it is an important reference work for anyone involved in renewable energy.
The use of the term "Anaerobic Biotechnology", rather the more restrictive term, "Anaerobic Digestion" is meaningful as one will see when examining the chapter headings. A perusal of the chapter heading will give an idea of the broad scope of this work:
1. OVERVIEW OF ANAEROBIC BIOTECHNOLOGY by S. Khanal
2. MICROBIOLOGY AND BIOCHEMISTRY OF ANAEROBIC BIOTECHNOLOGY by S. Khanal
3. ENVIRONMENTAL FACTORS by S. Khanal
4. KINETICS AND MODELING IN ANAEROBIC PROCESSES by K. Sharma
5. ANAEROBIC REACTOR CONFIGERATIONS FOR BIOENERGY PRODUCTION by S. Khanal
6. MOLECULAR TECHNIQUES IN ANAEROBIC BIOTECHNOLOGY: APPLICATION IN BIOENERGY GENERATION by S. Dhamwichukorn
7. BIOENERGY RECOVERY FROM SULFATE-RICH WASTE STREAMS AND STRATEGIES FOR SULFIDE REMOVAL by S. Khanal
8. BIOENERGY GENERATION FROM RESIDUES OF BIOFUEL INDUSTRIES by S. Khanal
9. BIOHYDROGEN PRODUCTION: FUNDAMENTALS, CHALLENGES, AND OPERATION STRATEGIES FOR ENHANCED YIELD by S. Khanal
10. MICROBIAL FUEL CELL: NOVEL ANAEROBIC BIOTECHNOLOGY FOR ENERGY GENERATION FROM WASTEWATER by H. Liu
11. PRETREATMENT OF HIGH SOLIDS WASTE/RESIDUES TO ENHANCE BIOENERGY RECOVERY by S. Harikishan
12. BIOGAS PROCESSING AND UTILIZATION AS AN ENERGY SOURCE by S. Harikishan
Developers of ethanol, biodiesel and algal renewable energy systems should particularly note Chapter 8 which describes how anaerobic digestion can clean up waste materials from their processes, producing additional energy and enhancing their financial return.
This is a reference book that belongs on the desk (not the bookshelf) of every serious practitioner and investor in the renewable energy field.
