AB Discarded red beetroot (DRB) is an organic waste produced in the food processing industry, rich in phytochemicals andsugars. This study compares biorefinery schemes for the valorisation of DRB. Two different alternatives were compared toselect the most favourable considering global yields and production costs. In scenario 1 (multi-product biorefinery), 0.9 g ofphenolics and 0.8 g of betalains were recovered from 100 g of DRB (on dry basis). After extraction, the solid fraction wasfed to enzymatic hydrolysis and fermentation to obtain 2,3-butanediol (2,3-BDO) with Paenibacillus polymyxa, achieving aglobal yield of 9.3 g/100 g DRB. In scenario 2, all the DRB was subjected to enzymatic hydrolysis and subsequent fermenta-tion with P. polymyxa, obtaining a 2,3-BDO global yield of 25.5 g from 100 g DRB. The economic evaluation indicated thata multi-product biorefinery could be the most cost-effective alternative for DRB valorisation, leading to minimum sellingprices competitive with the petrochemical route. Thus, the potential for the efficient use of DRB in an integrated biorefineryfor the production of high value-added products was demonstrated.
