Brewery's residual streams exploitation through anaerobic digestion and nanocellulose production

The aim of this work is to evaluate the feasibility of the implementation of a residual streams' treatment system, meant to exploit the potential of a brewery's waste production. Breweries main byproducts consist of barley's spent grain (BSG) and wastewater. Conveniently treated mixture of BSG and wasterwater was separated by phase: the liquid part was employed to feed an anaerobic digester, while the solid fraction was used to synthesize both cellulose nanofibers and nanocrystals
