WHEY2VALUE - Valorising waste whey into high value products

Whey2Value is a patented technology, which converts acid waste whey from dairy factories into high value animal feed products (vitamin B12) and clean water in the same process.


Acid waste whey is a major environmental issue for the world’s dairy industry and its disposal is very expensive.
Whey is a large volume by-product of cheese production, generating worldwide 190 million tons/year, of which only 50% is processed into food and feed products at high costs.
Approximately 50% of whey (mainly acid whey) is discarded and must be treated at wastewater stations or using other costly disposal technologies, presenting a huge economic and environmental burden to the industry.

Current waste whey generation process


  • unique and economic bioprocess to utilize whey as a primary substrate for microbial fermentation
  • sustainable production of high-value products from waste
  • complete conversion of acid whey into vitamin B12 contained in protein rich biomass, and purified water
  • B12-enriched biomass used as high quality animal feed
  • purified water can be recycled as technological water by dairy factories, further reducing their environmental footprint



  • patented technology
  • creating vitamin B12 from acid waste whey
    • lower production costs
    • lower investment costs
    • lower operational costs
    • better product quality for competitive price for premix industry
  • lower environmental footprint (clean water)
  • potential market leader in B12 animal feed application market in 2020
  • better quality of vitamin B12 (non-GMO, no cyanide, natural-organic form
