AB This work is focused on the development of a sustainable process for the valorisation of the main by-productgenerated in the brewing industry, the brewer’s spent grain (BSG). A two-step process combining subcriticalwater treatment and pervaporation (PV) was proposed to hydrolyse the hemicelluloses fraction of this lignocellulosic biomass and further removal/recovery of some of the degradation products of sugars by using twodifferent organophilic membranes, polydimethylsiloxane (PDMS) and polyoctilmethylsiloxane (POMS) membranes. Specifically, furfural is the dehydration product of pentoses and it is one of the top biomass-basedchemicals being an important platform chemical. For synthetic binary mixtures, lower total permeation fluxbut higher enrichment factors for furfural were determined for POMS. When dealing with subW hydrolysates,POMS membranes yielded the highest furfural recovery, 94.1 %, with permeate concentrations as high as 40 g⋅L1. Furthermore, it was assessed that PV is a suitable detoxification method that yielded a retentate nearly free offurfural allowing its use as growth media in the opposite to the subW hydrolysate with inhibitory furfuralconcentrations for microbial bioprocesses.
