Bioenergy Production By Anaerobic Digestion

Interest in anaerobic digestion (AD), the process of energy production through the production of biogas, has increased rapidly in recent years. Agricultural and other organic waste are important substrates that can be treated by AD. This book is one of the first to provide a broad introduction to anaerobic digestion and its potential to turn agricultural crops or crop residues, animal and other organic waste, into biomethane. The substrates used can include any non-woody materials, including grass and maize silage, seaweeds, municipal and industrial wastes. These are all systematically reviewed in terms of their suitability from a biological, technical and economic perspective. In the past the technical competence and high capital investment required for industrial-scale anaerobic digesters has limited their uptake, but the authors show that recent advances have made smaller-scale systems more viable through a greater understanding of optimising bacterial metabolism and productivity. Broader issues such as life cycle assessment and energy policies to promote AD are also discussed.

Anaerobic biotechnology is a cost-effective and sustainable means of treating waste and wastewaters that couples treatment processes with the reclamation of useful by-products and renewable biofuels. This means of treating municipal, agricultural, and industrial wastes allows waste products to be converted to value-added products such as biofuels, biofertilizers, and other chemicals. Anaerobic Biotechnology for Bioenergy Production: Principles and Applications provides the reader with basic principles of anaerobic processes alongside practical uses of anaerobic biotechnology options. This book will be a valuable reference to any professional currently considering or working with anaerobic biotechnology options.

This book focuses on biogas production by anaerobic digestion, which is the most popular bioenergy technology of today. Using anaerobic digestion for the production of biogas is a sustainable approach that simultaneously also allows the treatment of organic waste. The energy contained in the substrate is released in the form of biogas, which can be employed as a renewable fuel in diverse industrial sectors. Although biogas generation is considered an established process, it continues to evolve, e.g. by incorporating modifications and improvements to increase its efficiency and its downstream applications. The chapters of this book review the progress made related to feedstock, system configuration and operational conditions. It also addresses microbial pathways utilized, as well as storage, transportation and usage of biogas. This book is an up-to-date resource for scientists and students working on improving biogas production.

This open access book presents papers displayed in the 2nd International Conference on Energy and Sustainable Futures (ICESF 2020), co-organised by the University of Hertfordshire and the University Alliance DTA in Energy. The research included in this book covers a wide range of topics in the areas of energy and sustainability including: • ICT and control of energy;• conventional energy sources;• energy governance;• materials in energy research;• renewable energy; and• energy storage. The book offers a holistic view of topics related to energy and sustainability, making it of interest to experts in the field, from industry and academia.

Recent advances in technology to recover bioenergy from various feedstocks make them suitable alternatives to fossil fuel. This book contains several scientific discussions regarding microbes involved in biogas production, the anaerobic digestion process, their operation, and application for sustainable development. The book provides in-depth information about anaerobic digestion for researchers and graduate students. The editor sincerely thanks all the contributors, whose efforts have brought this book to fruition.

The bioenergy industry has grown rapidly since the turn of the century as politicians and energy producers have sought alternatives to fossil fuels. This has been driven by the growing consensus that carbon dioxide released during the burning of fossil fuels is causing global warming and climate change and the fact that fossil fuel reserves are finite and alternatives will have to be found. The expansion of the industry also came after a sustained period when farm prices were at historically low levels and the prospect of creating additional markets for agricultural produce was an attractive one. The bioenergy industry now represents a major market not only for established crops but also for novel crops and a variety of waste products. Its success, however, has led to a fierce 'food versus fuel' debate on the ethics of using food crops for energy production. This book provides a comprehensive introduction to bioenergy, covering liquid biofuels (bioethanol and biodiesel), biomass and biogas. It describes the feedstocks that are used, including established and potential crops as well as waste, the production processes, the products, the political interventions to support the industry and the impacts the industry has had on markets. It provides information on how this sector is developing and where it may be headed, and aims to give a balanced view on the arguments for and against the exploitation of different bioenergy sources. It would make an excellent entry-level textbook on this fascinating and rapidly changing topic, but is also accessible to the non-expert who wishes to have an overview of an industry that is already having profound effects on agricultural and energy markets around the world.

Scientific Essay from the year 2017 in the subject Energy Sciences, grade: N.A., Swedish University of Agricultural Sciences (SLU), course: Processing Biomass, language: English, abstract: The extensive use of fossil fuels has created a global problem of pollution and other environmental menace. Nevertheless, there is huge increase in the awareness and global involvement in the environmental conservation and sustainable ecosystem. This impetus in the natural conservation inspired to think for the alternative and renewable resources to meet the energy demand of the increasing population. The concept of bioenergy is one of the very important part and pivotal factor of the recent trends in the alternative energy regime. In this review, a brief introduction of the bioenergy and biomass processing is presented with the overall reconsideration and future overview of the bioenergy and society.
