Our process
How it’s made
Most everyday consumer and industrial products are made using non-renewable resources, such as petrochemicals. The overuse of these finite resources is not sustainable.
Bio-based 1,3-propanediol (PDO) is manufactured through a proprietary fermentation processing using plant-derived glucose instead of petroleum feedstocks.
Harvest
Renewably sourced feedstocks are harvested, dried and then wet-milled to create a range of carbohydrate-rich feedstocks such as glucose.
Fermentation
Glucose is converted into 1,3-propanediol using a patented microorganism under exact temperature and conditions.
Refining
The 1,3-propanediol is refined to a final purity of 99.7% by deactivating and removing the microorganism, water and other byproducts.
Production from the ground up
The manufacturing plant in Loudon, TN, is located adjacent to DuPont Tate & Lyle’s corn wet mill that supplies glucose from corn starch. The glucose is converted to 1,3-propanediol through a fermentation process that uses a patented microorganism under exact temperatures and conditions.
