Founded by Andras Forgacs, Modern Meadow is one of the first companies to use cellular agriculture to grow animal leather from cell cultures. Instead of creating animal skin cells for leather, Modern Meadow focuses on producing the skin protein collagen from yeast via fermentation. Collagen is the main material that makes up leather after every other component of the animal hide is discarded. By focussing on producing collagen directly, Modern Meadow offers a more sustainable way to produce leather that avoids the waste conventional leather production is associated with.
