Sustainability of Biorefineries: Challenges Associated with Hydrolysis Methods for Biomass Valorization

Biorefineries are mechanisms for adapting modern technologies toward the goals of recovery and aggregation of biomass value by creating processes that are renewable and environmentally friendly. The transformation of biorefineries to industrial realities is an area of intense study worldwide. Creation of more efficient systems requires hydrolysis processes that maximize the fractionation of biomass structure to produce high yields of several products. Scientific studies search to fill gaps in previously developed hydrolysis methods that may be coupled to biorefinery processes. There is great interest in advances in biomass enzymatic hydrolysis technologies that aim to convert complex compounds efficiently in innovative clean technology. This review will explore current scientific works that search integration of multiple processes through efficient hydrolysis methods for converting biomass, finally realizing the biorefinery concepts.
