'This book provides an excellent practical overview of biogas extension programmes, discussing challenges faced in different parts of the world, and the initiation and management of implementation programmes. It provides a clear overview of how anaerobic digestion actually works, focusing on design aspects that will help the reader to select a digester design, set it up and keep it going. It deals with the equipment needed to use the gas, and the important issue of how to use the valuable bioslurry residue produced by the digestion process. The book is thorough and well written from a practical perspective. I highly recommend it to anyone interested in practical implementation of small-scale digesters in rural areas.' Jo Smith, Professor of soil organic matter and nutrient modelling, University of Aberdeen, UK 'David Fulford's extensive knowledge of biogas through decades of work in the UK and particularly overseas has been brought into this excellent and timely book which is concerned with technical aspects of biogas use in rural communities.' Maria M. Vahdati is a lecturer in Renewable Energy at the University of Reading, UK. 'Anyone involved in biogas work will treasure this book because it provides details of the science of biogas, implementation and management of biogas programmes. David Fulford once again helps us think more clearly about important issues in rural biogas implementation.' Vianney Tumwesige of Green Heat (U) Ltd, Kampala, Uganda 'Small-scale Rural Biogas Programmes is an excellent update in the field of biogas, which is a potential source of fuel around us. It is a useful reading material for Students of Environmental Science, and a reliable reference for those beginning and running biogas programmes.' Ainea Kimaro won the Ashden Awards 2005 and is the Managing Director for Biogas and Solar Co. Ltd, Bagamoyo Tanzania 'Every farm in the world should have an anaerobic digestion (AD) plant, converting human and animal waste and other organic matter into valuable fertiliser and energy. At a time when natural resources are being depleted at an ever-faster rate, we ignore the potential of recycling at our peril. And every farmer should have a copy of this invaluable handbook, into which David Fulford has packed the technical knowledge and wisdom he has acquired over many years of designing, installing and operating AD plants all over the world.' James Skinner, Trustee, Organic Research Centre; Trustee Emeritus, New Economics Foundation. 'This book, by a leading expert in biogas, will continue to encourage governments to be shining examples, promoting biogas as a truly safe, healthy and effective renewable energy in rural and urban areas.' Ken Afful Ph.D., Executive Chairman, Organisation Development Centre, Inc.
David J. Fulford is a founding trustee of SKG Sangha, with nearly 40 years of experience of working as an expert in the biogas industry. He was part of a team that started the national biogas programme in Nepal, and led evaluations of the programmes that succeeded it.
