The PLA polymer used for the production of CornLeaf yarn is not made from oil derivatives but is obtained from renewable agricultural resources.
Ingeo PLA polymer is produced from dextrose (sugar) obtained from the processing of corn grown for other industrial applications. The quantity used is 0.0005% of total world corn production, and thus there is no impact on food prices or food availability. Ingeo PLA polymer production technology does not necessarily require the use of corn. What is needed is any product that contains sugar. Sugar beets, wheat or sugar cane can also be used (source: www.natureworksllc.com).
