    This book provides comprehensive and simplified coverage of fundamentals of biogas such as production, purification, storage, methods of improving yield and utilization, types, construction, design and operation of biogas plants. It covers stepwise design and a manual for construction of biogas plants including a planning guide, profitability analysis and evaluation of biogas plants. The biogas energy profile in Nigeria is exclusively covered.


    • Explores planning for biogas plants as a pre-requisite to develop a functional plant balancing energy production and consumption.
    • Gives out detailed provision of the types of substances that are and can be used for biogas production covering animal, municipal, and industrial wastes.
    • Provides knowledge for aspiring biogas producers as well as decision makers, specifically in the context of Nigeria.
    • Covers use of digestrate for anaerobic digestion as a waste treatment method and on the input (feedstock) to the biogas plant.
    • Compares carbon dioxide emissions from biogas plants with fossil fuel plants.

    This book aims at Graduate Students and Researchers in Agricultural, Environmental, Chemical, Civil and Energy engineering and related professional audience.
