ZestBio Orange Bottles (UC Berkeley)

Team Members: Ryan Protzko, Luke Latimer

School: UC Berkeley

Each year, over 4 billion pounds of citrus pulp waste are produced by the juicing industry in the USA and Brazil. This waste has caused significant disposal problems, but could be repurposed as a polymer to account for all the plastic bottles required by the orange juicing industry. The ZestBio Orange Bottle project is a synthetic biology effort that aims to convert citrus pulps and peels into plastics using eco-friendly conversion technologies. This project aims to give familiar wastes new life by fermenting them with highly engineered microbes that can produce chemicals normally produced from oil. Put your orange juice back in the peel with ZestBio plastics.
