| Abstract |
Brewer's spent grain (BSG) is the major by-product of the brewing industry. BSG is principally composed of carbohydrates and proteins, with substantial amount of lipids. Presently, BSG usage is restricted to low-grade applications such as ruminant feed or landfills. The high volume, nutrient-rich composition, low cost (V35/ton), abundance, and around the year availability, makes it a promising and renewable feedstock for biorefinery development. The current review begins with beer production process, where BSG is produced. Further, it appraises emerging biotechnological advancements and green processes targeting BSG valorisation ensuring maximal resource recovery. Particularly, it illustrates diverse marketable products obtained by repurposing carbohy-drate and protein fraction of BSG using either isolated or cascading approach. We believe that this review will encourage more research groups to work on developing innovative technol-ogies for integrated and holistic valorisation of BSG. Inclusive efforts towards reduced water consumption and waste mini-misation is further advocated, which are presently primary chal-lenges associated with beer industry. It will leave a significant imprint on environmental sustainability and pave a way for developing circular bio-based economy. |
