**Danimer Scientific,** formerly known as **Meredian Holdings Group Inc.** and **MHG**, is a [biopolymer](/source/Biopolymer) manufacturer headquartered in [Bainbridge, Georgia](/source/Bainbridge,_Georgia).

Danimer Scientific owns the patent for Nodax medium-chain-length branched [polyhydroxyalkanoates](/source/Polyhydroxyalkanoates), mcl-PHA. The company uses PHA and other biopolymers to create a range of applications such as [additives](/source/Polymer_additive), aqueous coatings, extrusion coating, extrusion [lamination](/source/Lamination), [fibers](/source/Fibers), film resins, hot melt adhesives, [injection molding](/source/Injection_molding), [thermoforming](/source/Thermoforming) and wax replacement [polymers](/source/Polymers).[1] In addition, Danimer Scientific offers research and development in the formulation of biopolymers. Danimer Scientific also provides toll manufacturing and [compounding](/source/Compounding) services, allowing partners to use the Bainbridge facility to manufacture products.[2]

## History

### Danimer Scientific

Danimer Scientific was founded in 2004 to create biodegradable and [sustainable](/source/Sustainability) solutions to the global dependency on traditional plastics, by using biopolymer materials such as [polylactic acid](/source/Polylactic_acid) (PLA). Danimer Scientific specializes in customizing biopolymer formulations.

In 2006, the [Small Business Innovation Research](/source/Small_Business_Innovation_Research) (SBIR) program awarded Danimer with a Phase 1 monetary grant of $80,000 for the "Creation of Cost Competitive Biodegradable Films from Renewable Resources for Agriculture". The following year the SBIR awarded the company with a Phase 2 monetary grant of $346,000 for the same title, stating that the project's objective was to use renewable materials to develop agricultural mulch films that could adequately degrade before the next growing season[3]

The company received the Sustainability Award from the [Specialty Coffee Association of America](/source/Specialty_Coffee_Association_of_America) (SCAA) in 2007 for the Ecotainer coffee cup, which used a plastic biopolymer derived from corn for the inner lining.[4]

In 2010, Danimer Scientific received a contract for $846,828 from the organization, Research Partnership to Secure Energy for America (RPSEA) to develop an environmentally friendly [fracturing](/source/Fracturing) treatment for [hydrocarbon](/source/Hydrocarbon) production, now known as SqueezeFrac.[5]

In September 2011, Danimer Scientific and minority business enterprise, Sijo Global Partners, formed a strategic affiliation where Sijo would offer Danimer’s bioplastic products to market leaders and brand owners.[6]

In January 2013, Danimer and Henkel formed a partnership to further develop bio-based hot melt adhesives for [polyethylene terephthalate](/source/Polyethylene_terephthalate) (PET) container packaging that are made with 50% renewable content or higher.[7]

### Meredian Inc.

Originally formed in 2004, Meredian Inc. manufactured PHA for Danimer Scientific.[8][9]

Danimer and Meredian purchased [Procter & Gamble](/source/Procter_%26_Gamble)’s intellectual property on PHA technology in 2007.[9][10]

In February 2014, Danimer Scientific and Meredian Inc. merged into MHG.[1][11] In March 2014, the company received a Food and Substance Contact Notification approval from the United States Food and Drug Association (FDA).[12] The sole-verification guarantees that the biopolymers are safe to use for food contact and are classified as non-hazardous waste after disposal.[13]

Stephen Croskrey was announced as [chief executive officer](/source/Chief_executive_officer) of MHG in May 2016.[14] The company's name changed to Danimer Scientific was officially announced in October 2016.[15]

In March 2025, Danimer Scientific filed for [Chapter 11 bankruptcy](/source/Chapter_11_bankruptcy) protection after a series of layoffs.[16][17][18] In June 2025, Teknor Apex acquired Danimer Scientific for $19 million.[19][20][21]

## PHA Patents

Main article: [Polyhydroxyalkanoates](/source/Polyhydroxyalkanoates)

Danimer Scientific's PHA has received several certifications for [biodegradability](/source/Biodegradability) including: anaerobic and aerobic digestion in soil, freshwater, marine, industrial and home composting.[22][23][24][25] The patented version of Danimer Scientific's mcl-PHA is known as Nodax and is the primary product developed for commercial manufacturing.[26] Danimer Scientific's Nodax PHA is a class of bioplastics produced from bacterial microorganisms that store PHA [polyesters](/source/Polyesters) for energy in their cell walls. These microbes feed upon plant-based oils procured from non-food sources.[10] Plant based oils are transferred to Danimer Scientific’s [proprietary](/source/Trade_secret) bio-reactors and fed to naturally regenerating, soil-borne [bacteria](/source/Bacteria) who produce PHA through [biosynthesis](/source/Biosynthesis).[27][28] The reactive extrusion process mixes and compounds the bioplastic materials in a unique proprietary procedure that creates a customized biopolymer [resin](/source/Resin) pellet.[10][29]
