This research book is mainly focused on giving a very critical insight towards solving the energy crisis and shortage that our world has been currently faced with and in the future as well.Finding a new source of energy is a very critical step for the replacement of fossil fuels with bio-fuels (which are renewable and pollution free). The major problems so far in this regard are a food vs fuel myth and the SCG which is investigated in this research book brings a very interesting idea of producing bio-fuel from a non edible and a potential waste from coffee brewing industries so this in turn will play a very great roles both in waste minimization and solving a food vs fuel myth as well. In closing, this research book will be a very fascinating tool for both academicians and researchers working on a bio-fuel processing stream and also it will serve as a very good information conveyor for anyone interested in science.
