Abstract: Biomass pretreatment is a highly expensive process used in bioethanol production from lignocellulosic feedstocks. The existing pretreatment methods are not commercialized due to two significant bottlenecks faced by the bioethanol industry such as higher operating cost and capital investment. Hydrodynamic cavitation technology is successfully demonstrated in the diversified fields. Hydrodynamic cavitation or its combinations is a viable technology for biomass pretreatment. This technology requires lesser energy inputs in terms of thermal or electrical energy as compared with other energy-intensive pretreatment methods. Other advantages of this technology are simple in reactor construction and easy to upscale. The combined hydrodynamic cavitation with alkali or biocatalyst showed positive results for different lignocellulosic biomass feedstocks. There is more scope for this technology to adopt in commercialization scale in both bioethanol and biorefinery industries.
