Demirbas... distills material from some of the hundreds of papers he has contributed to the field into a detailed and useful reference guide... The book is amply and appropriately supplemented with clear figures, helpful flowcharts, chemical equations, and tabular data... Those seeking a thorough technical overview of the range of feedstocks and technologies available for biofuel production will find this book extremely useful... Highly recommended.
