Basics, Planning, and Construction. This book, written by experienced scientists and practitioners, conveys the fundamentals of biogas production and covers the technology of biogas plants in detail and with practical relevance (containers, stirrers, gas storage, and associated operating facilities) including all important components and constructions. The authors also discuss the planning of biogas plants, address costs and economic viability, and present example plants with operational results from Germany and other European countries. A dedicated chapter focuses on the co-fermentation of organic residues (e.g., from food processing), which can often significantly improve the economic viability of biogas plants. This book is intended for farmers, agricultural consultants, and anyone looking to design or build biogas plants.
