Anaerobic digestion of biomass to biogas, commonly occurring in natural anoxic ecosystems, is an excellent method for utilizing wastes and producing green energy. This book presents examples of local installations of AD, or their proposals, located at small factories, workplaces, and in rural areas and housing complexes. The facilities consider the specific nature of the region, site conditions, and specificity of the utilized wastes. They protect the environment and ensure dispersed energy production. The latter is of great economic significance due to its closeness to end customers. Small local installations expand the pool of renewable energy on a global scale.

Small-scale Rural Biogas Programmes provides a comprehensive overview of the existing knowledge covering: the history of biogas programmes, the technology behind them, the value of biogas effluent as compost, details of the main domestic biogas plant designs, how biogas extension programmes work, and how they could be replicated.

Waste generation from industrial and domestic sectors is imposing a very challenging environment and the intervention of biotechnology offers a viable solution for their effective management. This book deals with the employment of biotechnological aspects for waste treatment including the basic concepts, biochemical processes, and various technologies for pollutant reduction and production of value-added products for a cleaner environment. It covers different aspects of biotechnology in the conservation of environment dealing with the sustainable management of waste through the concept of waste-to-economy along with the management of environmental pollutants and natural resource conservation. Focuses on ecological approaches i.e., the use of biocatalysts and biotechnological approaches for waste management Explores the different biotechnology-based solutions for the removal of environmental pollutants Covers various microbiological routes, technological options for waste to energy, removal of contaminants, and the production of value-added products Reviews the bioremediation potential of microbial strains and enzymes Explores the significant routes of biotechnological means of obtaining eco-friendly products substituting the hazardous chemical-based products This volume is aimed at researchers and professionals in environmental, biotechnology, and chemical engineering.

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.

With increasing pressures to utilize wastes effectively and sustainably, biogas production represents one of the most important routes towards reaching renewable energy targets. This comprehensive reference on the development and deployment of biogas supply chains and technology reviews the role of biogas in the energy mix and outlines the range of biomass and waste resources for biogas production. Contributors provide detailed coverage of anaerobic digestion for the production of biogas and review the utilization of biogas for various applications. They consider all aspects in the biogas production chain from the origin of the biomass feedstocks, feedstock selection and preparation, the anaerobic digestion process, biogas plant equipment design and operation, through to utilization of the biogas for energy production and the residue, the digestate, which can be used as a biofertilizer. The book also addresses biogas utilization, and explores environmental impacts and commercial market applications.

This edited volume looks at energy poverty, an issue whose pivotal role in the fight for human development is only now being recognised by policymakers. Nearly one quarter of humanity still lacks access to electricity. Close to one third rely on traditional fuels like firewood and cow dung for cooking, at great cost to their health and welfare. While most prevalent in parts of Africa and Asia, energy poverty is a global problem which concerns us all. This book, which brings together economists, policymakers, entrepreneurs, and other practitioners from all over the world, is dedicated to a single goal: finding a solution to this haunting problem. It is part history, part economics, part political analysis, part business case review, and part field handbook. Part One focuses on defining and measuring the problem and benchmarking progress in solving it, an obvious prerequisite to any successful energy-access policy. Part Two reviews past and current energy access programs, with an eye towards finding out what worked and what didn't and what can be replicated elsewhere. These case reviews are told as seen on the ground - China's experience by top Chinese officials and Africa's by African regulators and scholars. Based in part on those cases, the book's last, more forward-looking section aims to present practitioners with a tool kit, a menu of options to speed up their efforts. The energy access agenda is gaining traction at a time of rising concerns about climate change and resource constraints. This book shows that bringing modern energy to those who lack it not just a moral imperative, but will likely benefit the world as a whole without harming the environment or unduly stretching finite resources.

Intended to assist engineers, government officials and funding agencies to meet present and future challenges and make decisions on the promotion of anaerobic digestion as an alternative source of energy.
