Fermentation: A Sustainable Solution

Fermentation offers numerous environmental benefits, such as reducing carbon footprints and conserving resources. For example, corn's fermentation-made protein has a 70% lower carbon footprint than chicken. Additionally, precision fermentation for whey protein emits 97% fewer greenhouse gas emissions compared to traditional methods. Furthermore, fermentation enables the upcycling of waste streams from other industries, such as using spent grain from breweries or corn husks as feedstock. These advancements in fermentation hold promise for a more sustainable future.
