Abstract: The present invention relates to a time-, cost-, and energy-efficient process for concentrating saccharification hydrolysates during bio- refinery operations and a system for the same. The specific bio-refinery unit-operation for concentrating saccharification hydrolysates uses a packed-bed matrix derived from waste oyster shells. The matrix, partially bio-demineralized by endolithic fungi, is loaded into cartridges for simultaneous selective adsorption and evaporative concentration of saccharification hydrolysates. The process employs a mono-/multi-cartridge sugar-concentrator device operating at 76–90°C. Furthermore, the process helps in achieving ~2.5–3.9-fold increase in sugar concentration, and is capable of processing ~9 L of hydrolysate in ~2.5 hours. The method demonstrates a 14-fold reduced energy consumption and up to 25-fold reduced time compared to conventional techniques. The unit-operation-resultant sugar- shell cakes can be stored for 6months to 1 year under appropriate refrigeration, and when required, the monomeric sugars can be eluted with 96% efficiency to be directly used for ethanol fermentation. The selectively-sugar-adsorbing matrix is reusable for at least 10 cycles without a loss in its efficiency. This straight-forward and cost-effective process significantly reduces capital, operational, and labor expenditures incurred in bio-refinery operations.
