A symbol of added value, the DuPont Renewably Sourced Materials icon represents the rigorous standards and uncompromising quality of our products.

The DuPont Renewably Sourced Materials icon was created to advocate bio-based technology and provide a compelling way for products to differentiate themselves in the marketplace.

Use of the DuPont Renewably Sourced Materials icon indicates that a product contains a minimum of 20% renewably sourced content by weight. Our products, Susterra^™ propanediol and Zemea^™ propanediol, are 100% renewably sourced.

The content of products bearing the DuPont Renewably Sourced Materials icon is determined by carbon dating, a well-accepted technique used by ASTM International and the USDA standard for its preferential procurement program.
