Food waste that is generated is a major global problem, not only for economic but also for environmental reasons. An alternative for minimising the amount of waste sent to landfill is to use it as a raw material in transformation processes to obtain value-added products. Specifically, one of the possible options for the revaluation of organic waste containing carbohydrates is to use it as a substrate for obtaining biofuels such as bioethanol or biobutanol. These fuels represent a renewable alternative to the use of fossil fuels, it is of great interest the development of processes that allow them to be obtained from waste materials such as those proposed here.
