Using Research and Development to Advance Taraxacum Kok-Saghyz (BUCKEYE GOLD) As a Viable Source of Ohio Natural Rubber

For buckeye gold to become a viable source of natural rubber of the United States, and especially Ohio, progress must be made along the entire production chain from plant to product. Planting density trials indicate that commercially viable rubber yields may be achievable without overwintering the crop.  Cold-storage of fall-harvested roots triggers immediate catabolism of the storage carbohydrate inulin and delayed synthesis of new rubber.  Rubber quality evaluation indicates that buckeye gold rubber is very similar to Hevea brasiliensis rubber, including proteins that cross-react with human Type I latex allergy, high molecular weight and insoluble gel.  Roots from eight acres of buckeye gold will be harvested this year and processed using a modern pilot plant constructed based on the Eskew design of the 1940’s. Modification and additions to the process have been made to improve rubber purity and yield.
