This book is an invaluable souce of information on various biomass feedstocks and biofuel production methods, and their uses. The chapters in this book cater to the needs of researchesrs working in the areas of biohydrogen, bioethanol, biomethane and biorefineries. Biomass, as a renewable feedstock, can make a substantial contribution to meeting future energy demands in a sustainable way. However, conversion of biomass into liquied fuel involves complicated processes that are not well understood. This book discusses the processes involved in the biological conversion of biomass in detail and compares them in terms of selectivity and cost effectivness. Furthermore, the book includes comparisons to existing chemical conversion methods, enabling engineers and policymakers to make informed decisions.
