NatureWorks (Minnetonka, Minn.; www.natureworksllc.com) announced that it has signed a contract to license Plaxica’s Optipure chemical processing technology for the production of D-lactic acid. The license provides NatureWorks with a low-cost route to produce D-lactic acid, a building block for a further range of performance Ingeo polylactic acid (PLA) grades. This investment is part of NatureWorks’ longterm strategy for leading the market with cost effective, functional biopolymers.
Commenting upon the license investment, Bill Suehr, NatureWorks Chief Operating Officer, said, “After investigating multiple sourcing strategies for D-lactic acid, we are pleased to be licensing the Plaxica Optipure process. Access to competitively priced D-lactic acid is fundamental to NatureWorks’ strategy to broaden our Ingeo product offering.”
Suehr explained that while small volumes of D-lactic acid have previously been available from producers in Europe and Asia, they have until now been at a substantive price premium to the L-lactic acid which NatureWorks uses today. “D” and “L” lactic acid monomers are essentially identical yet “mirror images” of one another. In combination, the two can produce polymers that offer unique features such as higher melt point and melt strength. NatureWorks expects to begin sampling new Ingeo grades to customers in the second half of 2017.
Phil Goodier, Plaxica’s CEO, said, “We are delighted to be working with NatureWorks, one of the world’s leading biopolymer companies, and proud that the acknowledged brand leader in PLA has selected Plaxica’s technology. This is an important milestone in Plaxica’s development as a global technology licensing business.”
