Book Description
The concern about using organic waste as a renewable energy source is a critical worldwide issue. In this area, anaerobic digestion (AD) seems to be a promising solution because of the significant reduction of waste quantity and generation of valuable products such as biogas, regarded as being a good energy carrier and digestate with high nutritional potential for agriculture. The current trends in AD focus on improving the efficiency of the process to make this a cost-effective treatment. Depending on the source (agricultural, municipal, or industrial), organic waste varies considering both its composition and structure, and thus the bioaccessibility and biodegradability. Accordingly, materials rich in carbohydrates, proteins, and fats require different operational conditions to overcome technological problems and minimize the risk of disruption or failure of the anaerobic systems. Different strategies can be used to enhance biogas production, including waste pretreatment (physical, chemical, physico-chemical, biological, and combined), two-stage AD (temperaturephased AD and two-phase AD), anaerobic co-digestion (two-substrate and multi-substrate systems), and bioaugmentation (with natural strains or specialized consortia of microorganisms and genetically modified microorganisms or their consortia). Some of them enhance its accessibility and digestibility, while others improve nutritional balance, metabolic properties, and operational factors, facilitating synergistic effect of microorganisms. This book covers the current developments in the area of enhancing biogas production.

Book Description
Biogas Production covers the most cutting-edge pretreatment processes being used and studied today for the production of biogas. As an increasingly important piece of the "energy pie," biogas and other biofuels are being used more and more around the world in every conceivable area of industry and could be a partial answer to the energy problem and the elimination of global warming. This book will highlight the recent advances in the pretreatment and value addition of lignocellulosic wastes (LCW) with the main focus on domestic and agro-industrial residues. Mechanical, physical, and biological treatment systems are brought into perspective. The main value-added products from lignocellulosic wastes are summarized in a manner that pinpoints the most recent trends and the future directions. Physico-chemical and biological treatment systems seem to be the most favored options while biofuels, biodegradable composites, and biosorbents production paint a bright picture of the current and future bio-based products. Engineered microbes seem to tackle the problem of bioconversion of substrates that are otherwise nonconvertible by conventional wild strains. Although the main challenge facing LCW utilization is the high costs involved in treatment and production processes, some recent affordable processes with promising results have been proposed. Future trends are being directed to nanobiotechnology and genetic engineering for improved processes and products.

Book Description
Pretreatment of Biomass provides general information, basic data, and knowledge on one of the most promising renewable energy sources—biomass for their pretreatment—which is one of the most essential and critical aspects of biomass-based processes development. The quest to make the environment greener, less polluted, and less hazardous has led to the concept of biorefineries for developing bio-based processes and products using biomass as a feedstock. Each kind of biomass requires some kind of pretreatment to make it suitable for bioprocess. This book provides state-of-art information on the methods currently available for this. This book provides data-based scientific information on the most advanced and innovative pretreatment of lignocellulosic and algal biomass for further processing. Pretreatment of biomass is considered one of the most expensive steps in the overall processing in a biomass-to-biofuel program. With the strong advancement in developing lignocellulose biomass- and algal biomass-based biorefineries, global focus has been on developing pretreatment methods and technologies that are technically and economically feasible. This book provides a comprehensive overview of the latest developments in methods used for the pretreatment of biomass. An entire section is devoted to the methods and technologies of algal biomass due to the increasing global attention of its use. - Provides information on the most advanced and innovative pretreatament processes and technologies for biomass - Covers information on lignocellulosic and algal biomass to work on the principles of biorefinery - Useful for researchers intending to study scale-up - Provides information on integration of processes and technologies for the pretreatment of biomass

Book Description
This book highlights the current limitations of biogas production and yield and new avenues to improving them. Biogas production and yield are among the most important renewable energy targets for our world. Pursuing an innovative and biotechnological approach, the book presents alternative sources for biogas production and explores a broad range of aspects, including: pre-treatment of substrates, accelerators (enzyme-mediated) and inhibitors involved in the process of obtaining biogas and its yield, design specifications for digesters/modified digesters, managing biogas plants, microbial risk and slurry management, energy balance and positive climatic impacts of the biogas production chain, and the impacts on Human, Animal and Environmental Health (“One Health” concept for the biogas chain).

Book Description
Written as a practical introduction to biogas plant design and operation, this book fills a huge gap by presenting a systematic guide to this emerging technology -- information otherwise only available in poorly intelligible reports by US governmental and other official agencies. The author draws on teaching material from a university course as well as a wide variety of industrial biogas projects he has been involved with, thus combining didactical skill with real-life examples. Alongside biological and technical aspects of biogas generation, this timely work also looks at safety and legal aspects as well as environmental considerations.
