CJ Biomaterials ferments sugar to make plant-based polymers that microbes will consume. They can also be both, like the polymers made by CJ Biomaterials. A container made of pellets from CJ Biomaterials with food scraps could be sent to a composter, unlike a traditional plastic container. CJ Biomaterials feeds sugar to microbes that convert it to PHA for energy. CJ Biomaterials is part of the $32 billion South Korean conglomerate CJ Group.
