Sorona®
Polyester made from a genetically modified microorganism that produces 1,3-propanediol (PDO) from cornstarch. Derived from cornstarch, making it partially plant based. Fermentation of genetically modified cornstarch replaces chemical synthesis, and PDO is naturally produced (Bio-PDO). Less energy compared to petroleum-based traditional processes.
