ZestBio is a startup spun out of UC Berkeley that is harnessing the power of biology to convert low value, abundant fruit and vegetable byproducts like citrus peels and sugar beet pulp into high performing plastic bottles and ingredients for dishwasher detergents. This proposal aims to build off recent business and technical advances to scale the improved fermentation technology from bench to pilot scale. At scale, ZestBio aims to make products with superior performance and dramatically reduced environmental footprint compared to existing solutions.
