NatureWorks Ingeo biopolymer — made from plants, not oil — is the first polymer to earn a four-star “OK biobased” rating from the European certification organization Vinçotte of Vilvoorde, Belgium.
The Vinçotte OK biobased certification, which was introduced in September 2009, quantifies for consumers the amount of renewable carbon content in packaging materials and fibers, as well as in personal care, electronic, and other manufactured products. The Vinçotte OK biobased certification meets the ASTM D6866 standard for determining the renewable/biobased carbon content of products.
The certification recognizes four levels of renewable carbon content: one star for content comprised of between 20 to 40 percent biobased carbon, two stars for 40 to 60 percent, three stars for 60 to 80 percent, and four stars awarded for more than 80 percent biobased carbon content.
According to the test, NatureWorks Ingeo plastic resin is made from 99 percent renewable plant sugars — that is, renewable carbon. (In actuality, all of the carbon is biobased, but 99% reflects the accuracy of the test.)Every grade of Ingeo™ resin — 40 in all — received the four-star certification.
“We are proud to announce the first OK biobased certificates, and we congratulate NatureWorks on its across-the-board four-star rating,” said Petra Michiels, contract manager for OK biobased.“With the Ingeo resins now certified, the four-star rating can be used as the foundation for downstream products, earning them an OK biobased rating.”
“The OK biobased star rating serves as a sustainability indicator for consumers by identifying materials and products that are helping to alleviate the environmental problems associated with fossil fuels and greenhouse gases,” said Steve Davies, director of corporate communications and public affairs, NatureWorks.“Symbols on packages and products relating to the environment, such as the OK biobased stars, inform and influence consumer buying decisions.NatureWorks is proud to have the highest OK biobased certification ranking for the entire family of NatureWorks resins ranking supplied to the fibers and plastics markets."
