Designed as a practical introduction to biogas plant design and operation, the author covers both the biological and technical aspects of biogas generation. The full range of biogas substrates and processing modes is explained, from agricultural and industrial waste to marine algae and sediment. On-site use of biogas for conversion into electricity, fuel and heat is also discussed, as are safety and regulatory issues. Dozens of real-life examples of European biogas plants already in operation illustrate the contents, as do numerous schemes and diagrams, many of them in full color. Appendices contain key data as well as practical guides for the planning and building of tailor-made biogas plants.
