Whey Ethanol

Whey is a by-product of the cheese production process and contains protein, fat, lactose sugar, and salt. Whey is processed to recover the fat, protein, and sugars, which creates a low-value and high BOD whey permeate stream . Whey permeate contains lactose which can be fermented to produce ethanol, but it is not an ideal substrate due to:

  • low sugar concentration

  • high salt content

  • susceptibility to bacterial infection

Bio-Process has designed process systems and developed technologies for the efficient and economical production of ethanol and co-products from whey, whey permeate, permeate mother liquor, and lactose streams. 

Bio-Process Whey Technologies:

  • Improved Salt Tolerant Organisms

  • Reactor / Separator Systems

  • Bacterial Resistant System Design

  • High Ethanol Percentage Beer Production

  • Low Energy Ethanol Product Recovery

  • Versatile Production of Co-Products
