Life Cycle Analysis

The sustainability story for Sorona® starts at the very beginning and continues through to the consumer and beyond. DuPont™ Sorona® contains 37% annually renewable plant based ingredients by weight. (28% biobased carbon). A breakthrough in integrated science, Sorona® combines the best of chemistry, biology and material science resulting in this innovative product. Sorona® is an advanced material that offers a unique combination of attributes and benefits throughout the value chain..

The Sorona® sustainability story begins with the reduction of oil and continues through the product life cycle providing energy and production savings for every step of the value chain. In addition to reducing dependency on oil, the production of Sorona® saves energy and reduced CO2 emissionsthat have been shown to contribute to climate change, over the production of an equal amount of nylon. Sorona® fiber extrusion occurs at lower temperatures than other synthetic fibers, thereby reducing energy needs and costs. Fiber and fabric production costs are lower since Sorona® can dye at the boiling point of water with no additional heat, pressure, or chemical carriers. Consumers benefit from the longevity of Sorona® due to its fade resistance, wrinkle resistance and faster drying benefits. The versatility and adaptability ofSorona® fiber, can impart these environmental benefits to many end uses and fabric types including, wovens, knits, circular knits, warp knits and more.

Producing DuPont™ Sorona® uses 30% less energy and reduces greenhouse gas emissions by 63% compared to the production of an equal amount of nylon 6. What's more, Sorona® doesn’t use or contain heavy metals and requires no additional chemical treatments for stain resistance. Less energy, lower emissions, no added chemical treatments. With Sorona®, Less really is More.


Sustainability with Sorona® starts at the beginning with the ingredients used to make the polymer, to lower processing temperatures to produce fiber, to lower dye temperatures used to dye fabric all the way to the consumer by offering the ability to wash garments with Sorona® in cold water.And, since Sorona® dries quicker than other fibers, dryer time is also reduced thereby saving energy.Durability and an extended useful life of apparel also contributes to the ‘end to end’ sustainability story.


As the face fiber in a carpet, Sorona® is able to berecycled. Research proves that carpet face fiber made with Sorona® can be shaved from the carpet backing, repellitized, and spun into new fiber to include in new carpets..The beauty and performance or useful life of a carpet with DuPont™ Sorona® is extended due to the many benefits that Sorona® provides including durability, wear resistance and permanent stain and bleach resistance. With both performance and measurable environmental benefits, it’s easy to understand why Sorona® is the most revolutionary material to hit the carpet industry in over 20 years.
