This volume is fifth part of the five-part set on bioenergy research. This edited volume provides sustainable solution for all existing roadblocks in commercial bioenergy production. The book focuses on different types of obstacles involved in various bioenergy operations with detail remedy of the issue in a sustainable way. In spite of having number of potential advantages, all available bioenergy options are still far from smooth practical applicability, due to which they are still in pipeline phase to replace the fossil fuels. This book brings together the integrative approach to the readers, to connect with more viable bioenergy type on commercial scale, the existing issues and the feasible approaches to eliminate the bottlenecks in the process. Further, the book also uncovers the untouched area of bioenergy production technology by bringing forth unconventional methods, processes and parameters, which have scope to enhance biofuel production technology by "Lab to Land" methods. The book highlights aspect which are less studied or are very new in their industrial application of bioenergy production. The book presents relevant reading material for global researchers, academic institutions, research students, teachers, scientist as well as industries. Other four volumes of this set explore basic concepts, latest progress, commercial opportunities and bio-waste to energy conversion.
