Whey is the co-product of making Greek-style yogurt and is packed with probiotics, vitamins and minerals. Who would want to waste that?

We craft our products with unused ingredients and unparalleled sustainability, finding more ways to use more of what the world already produces. We’re building a movement to make our food system less wasteful, more equitable and more resilient.
