A Final Step to Renewably Sourced Products

Depending on the desired end product, the renewably sourced chemical building blocks may undergo further value-adding processes where materials science and chemistry are applied to create either high-performance materials or advanced biofuels. For example, DuPont Tate & Lyle Susterra™ renewably sourced™ propanediol (PDO) is polymerized with the monomer terephthalic acid (TPA) to create the high-performance polymer DuPont™ Sorona® — a material used in many forms such as fibers and molded parts across many applications.

Complete Compatibility

Inherent in any DuPont bio-based substitute for petroleum-derived building blocks or products, is the objective of making them as compatible as possible with existing assets. DuPont strives in many cases for "drop-in" compatibility — the ability to substitute a renewably sourced ingredient or product into existing systems, equipment and products, with little or no retrofitting.
