Verdezyne Opens Pilot Plant to Produce Bio-Based Adipic Acid for Renewable ‘Green’ Nylon

Demonstrates Proprietary Method for Producing Adipic Acid at Lower Costs than Petroleum-Based Alternatives

Verdezyne, Inc. (“Verdezyne”), a privately held industrial biotechnology company focused on producing renewable chemicals and fuels from non-petroleum sources has opened its first pilot plant to produce adipic acid, a key component of nylon 6,6.

The new facility, located in Carlsbad, California will be used to accelerate the commercialization of Verdezyne’s bio-based adipic acid, which is one of two components used to manufacture ‘green’ nylon 6,6 and thermoplastic polyurethane resins from renewable sources, such as non-food based vegetable oils.

“We are excited to achieve this key milestone,” said Dr. E. William Radany, president and CEO of Verdezyne. “This is the first demonstration of the production of bio-based adipic acid at scale from a non-petroleum source. Our novel yeast platform enables production of adipic acid at a lower cost than current petrochemical manufacturing processes.”

In addition to lower production costs, Verdezyne’s method for producing adipic acid offers a number of advantages over petroleum-based methods. The company’s yeast fermentation process uses non-food, plant-based feedstocks to produce a variety of commercial diacids. Moreover, Verdezyne’s production methods are expected to generate less CO2 and other pollutants as compared with incumbent methods.

A variety of products are currently produced worldwide from petroleum-based nylon, including engineered plastics, carpets, clothing and other assorted textiles. Production of these types of products translates to an adipic acid market of more than $6 billion globally.
“We are thrilled about the opening of our pilot plant,” said Dr. Stephen Picataggio, chief scientific officer of Verdezyne. “This plant will allow us to demonstrate the scalability of our process, validate our cost projections and generate sufficient quantities of material for commercial market development.”
