DuPont Tate & Lyle Bio Products, a joint venture between chemical giant DuPont and ingredients maker Tate & Lyle to replace petrochemicals in the making of apparel and textile fibres, is expanding its Tennessee manufacturing facility to increase production of bio-based 1,3-propanediol.

The Loudon-based facility will be expanded to increase production by 35m pounds. Engineering and construction is scheduled to start immediately and the project is expected to be complete by mid-2019.

Formed in 2004, DuPont Tate & Lyle utilizes a proprietary process that uses plant-based feedstocks to produce bio-based 1,3-propanediol. Today, the joint venture provides solutions for a variety of markets and applications through its bio-based performance brands Susterra and Zemea propanediol in addition to Bio-PDO, the key ingredient for DuPont Sorona high-performance polymers.

"Our continued growth is a testament to our ability to meet the performance requirements of demanding applications with our plant-based ingredients," explains Todd Sutton, president, DuPont Tate & Lyle Bio Products. "The versatility of the product has powered the Sorona fibre business growth as well as fuelled the expansion for Zemea and Susterra propanediol. The benefits of creating high-performing solutions in combination with renewability provides opportunities for us to continue to expand our market reach in the cosmetics, personal care, flavours, fibres and polyurethanes markets as well as other applications."

Sorona is a polymer that brings unique performance-based benefits to fibres used in apparel and carpet markets, while Zemea propanediol is a multifunctional, preservative-boosting humectant and ingredient that delivers high performance in a variety of consumer applications from personal care, flavours and pharmaceuticals to laundry and household cleaning. Susterra propanediol delivers high performance in polyurethanes, fluids and other industrial applications.
