Abstract

Graphical abstract: Highlights: Seawater can substitute freshwater at all stages of the biorefinery. Seawater can be a catalyst in lignocellulosic. biomass fractionation processes. Halophilic enzymes and yeasts perform an essential role in seawater-based biorefineries. State-of-art and main bottlenecks about seawater-based biorefineries are discussed. Seawater-based biorefineries contribute to the advancement of the circular economy. Abstract: Biorefineries are an essential step towards implementing a circular economy in the long term. They are based on renewable raw materials and must be designed holistically, recovering building blocks from being converted into several products. Lignocellulosic biomass is considered a critical pillar for a biologically based economy and a high value-added feedstock. The separation of the structural complexity that makes up the biomass allows the development of different product flows. Chemical, physical, and biological processes are evaluated for fractionation, hydrolysis, and fermentation processes in biorefineries; however, the volume of freshwater used affects water safety and increases the economic costs. Non-potable-resources-based technologies for biomass bioconversion are essential for biorefineries to become environmentally and economically sustainable systems. Studies are being carried out to substitute freshwater with seawater to reduce the water footprint. Accordingly, this review addresses a comprehensive discussion about seawater-based biorefineries focusing on lignocellulosic biomass conversion in biofuel and value-added products.
