In 2011, NatureWorks reported that it was working on process and capacity developments aimed at achieving the commercial production of the stereoisomer meso-lactide. The company confidently projected that by early 2013, it would be offering "thousands of tons of Ingeo M700 lactide." The big day finally arrived, as NatureWorks recently announced world scale availability of its new Ingeo M700, a high-purity, polymer-grade lactide rich in meso-lactide.
Ingeo M700 has been designed to "package and deliver performance and functionality all in one unique molecule," says the company. This is different than previous industry approaches, which have attempted to deliver the functionality requested by the market with mixtures of two different materials, L-lactide and D-lactide.
