Sustainable Solution

  • Production cycles are short, highly efficient, and not influenced by climate or environment which makes the supply more reliable
  • Lower carbon emissions, water consumption, and land use in compared to soy and beef

Circular Economy Model for
Yeast Protein Production

The sugar cane and beet molasses are the nutrient sources of yeast, and the wastewater of the production is the source of organic fertilizer for crop production. This allows you to use a high quality and sustainable vegan protein for your products.
