Recently, the production of bioethanol is shifted to secondary bioethanol which is produced from nonedible lignocellulosic feedstock to avoid the food versus fuel issue. Mango leaves, a kind of nonedible lignocellulosic material (LCM) that possess a relatively 80.7% of holocellulose (inclusive of cellulose and hemicellulose), appear to be potential candidate to serve as cheap substrate source for bioethanol production. Hence, the objective of this article is to present the current scenario and the potential of mango leaves as a substrate source for bioethanol production. This article also provides an overview on various process parameters such as temperature, pH, substrate concentration, and incubation time that required to be optimized for an efficient fermentation process in the bioethanol production from LCM. Apart from that, several integrated fermentation technologies in bioethanol production which include separate hydrolysis and fermentation, simultaneous saccharification and fermentation, simultaneous saccharification and co‐fermentation, and consolidated bioprocessing will also be discussed in this article. Based on the findings, it is clear that mango leaves have the potential to serve as feedstock for bioethanol production.
