POLYSORB® isosorbide USDA Certified Label

A U.S. Department of Agriculture Label

Lestrem, FR (Sept 28, 2021) — Roquette announced today that it has earned the U.S. Department of Agriculture (USDA) Certified Biobased Product label.

The following products are now able to display a unique USDA label that highlights its percentage of biobased content:

  • POLYSORB® PSA - isosorbide
  • POLYSORB® LP - isosorbide
  • POLYSORB® PA - isosorbide

The following Roquette products have also earned the USDA Certified Biobased Product Label:

  • BIOSUCCINIUM® with 100% biobased content.
  • BIOSUCCINIUM® S with 100% biobased content.

Third-party verification for a product's biobased content is administered through the USDA BioPreferred Program, an initiative created by the 2002 Farm Bill (and recently reauthorized by the 2018 Farm Bill). One of the goals of the BioPreferred Program is to increase the development, purchase and use of biobased products. The USDA Certified Biobased Product label displays a product's biobased content, which is the portion of a product that comes from a renewable source, such as plant, animal, marine, or forestry feedstocks. Utilizing renewable, biobased materials displaces the need for non-renewable petroleum-based chemicals. Biobased products, through petroleum displacement, have played an increasingly important role in reducing greenhouse gas (GHG) emissions that exacerbate global climate change.

Biobased products are cost-comparative, readily available, and perform as well as or better than their conventional counterparts.

“This makes our portfolio of performance materials more complete and attractive as alternative solutions for many industries like automotive, packaging and coatings. We receive a lot of requests from our customers and prospects for certifications like the USDA BioPreferred Program which appeals to consumers. We are proud of this achievement that will benefit our customers, consumers and the planet.” said Franck Thumerel, Head of Performance Materials at Roquette. 

"We applaud Roquette for earning the USDA Certified Biobased Product label," said Vernell Thompson, USDA BioPreferred Program. "Products from Roquette are contributing to an ever-expanding marketplace that adds value to renewable agriculture commodities, creates jobs in rural communities, and decreases our reliance on petroleum."

According to a report that USDA released in July 2019, biobased products contributed $459 billion to the U.S. economy in 2016 (a 17% increase from 2014) and support, directly and indirectly, 4.6 million jobs. The report's research team estimates the reduction of fossil fuels and associated GHG emissions from biobased products equivalent to approximately 12 million metric tons of carbon dioxide (CO2) prevented as of 2016.

The increased production of renewable chemicals and biobased products contributes to the development and expansion of the U.S. bioeconomy - where society looks to agriculture for sustainable sources of fuel, energy, chemicals, and products.

POLYSORB® isosorbide allows customers to choose a bio-based material with an improved environmental footprint to develop superior sustainable products such as polyesters, polycarbonates, polyurethanes, coatings, epoxy for the plastic packaging, automotive, opticals and C.A.S.E. markets. 

About the USDA BioPreferred Program and Certified Biobased Product label
The BioPreferred Program is a USDA-led initiative that assists the development and expansion of markets for biobased products. The BioPreferred Program is transforming the marketplace for biobased products through two initiatives: mandatory purchasing requirements for Federal Agencies and Federal contractors and voluntary product certification and labeling.
Biobased products span a diverse range of applications, such as lubricants, cleaning products, chemicals and bioplastics. The USDA Certified Biobased Product label communicates a product's biobased content. Expressed as a percentage, biobased content is the ratio of non-fossil organic carbon (new organic carbon) to total organic carbon in a product. New organic carbon is derived from recently-created materials. The total organic carbon in a product consists of new organic carbon and old organic carbon that originates from fossil carbon materials, such as petroleum, coal, or natural gas. More than 3,500 products have earned the USDA Certified Biobased Product label. To learn more about the USDA Certified Biobased Product label please visit, and follow on Twitter at
