Biobutanol has been emerging as a sustainable biofuel due to its superior form of heat content, sustainable volatility, better anti corrosive nature and more importantly low moisture content. The waste resources utilization for biobutanol production has sustainability and economic feasibility due to their easier availability and landfilling nature. The foremost limitations in the biobutanol development are lower yield rate, unavailability of feedstock and inhibitor formation. These obstacles are easily exterminated by the appropriate selection of waste biomass resources, few advanced metabolic engineering techniques and recent developments on integrated bioprocessing strategies with effective solvent recovery and purification methods. This review has been made to elaborate the various production techniques that have been enriched on biobutanol production from all the existing waste resources in last one decade and the highlights the research progress on biobutanol suitability in automotive applications. An elaborative discussion are undertaken on selection of waste feedstocks, superior pretreatment processes, selection of optimum strain, metabolic pathways of various microbes and separation techniques to enhance the economical biobutanol fermentation process. In a second phase of the review, the properties assessment of biobutanol and its technical suitability in spark ignition and compression engine are discussed in terms of performance, combustion and emission aspects. In the end, techno-economic analysis on biobutanol production is also provided to improve the commercial eminence on developing advanced techniques. Finally, the review report provided the route map towards the importance of developing efficacy integrated production techniques, research emphasis on flex fuel operation of biobutanol in hybrid configuration vehicles to meet the global demand in future.

生物丁醇由于其优异的热量含量，可持续的挥发性，更好的抗腐蚀性能以及更重要的是较低的水分含量，已成为一种可持续的生物燃料。用于生物丁醇生产的废物资源具有可持续性和经济可行性，因为它们更容易获得和填埋。生物丁醇开发中的最主要限制是较低的产率，原料的缺乏和抑制剂的形成。These obstacles are easily exterminated by the appropriate selection of waste biomass resources, few advanced metabolic engineering techniques and recent developments on integrated bioprocessing strategies with effective solvent recovery and purification methods. 进行了这次审查，以详细说明过去十年来从所有现有废物资源中丰富了生物丁醇生产的各种生产技术，并着重介绍了生物丁醇在汽车应用中的适用性研究进展。对废物原料的选择，优良的预处理工艺，最佳菌株的选择，各种微生物的代谢途径和分离技术进行了详尽的讨论，以增强经济的生物丁醇发酵工艺。在审查的第二阶段，从性能，燃烧和排放方面讨论了生物丁醇的性能评估及其在火花点火和压缩发动机中的技术适用性。到底，还提供了有关生物丁醇生产的技术经济分析，以提高开发先进技术的商业知名度。最后，审查报告提供了发展功效综合生产技术的重要性的路线图，研究重点是混合动力配置车辆中生物丁醇的灵活燃料操作，以满足未来的全球需求。
