Dionymer

What Dionymer does

Dionymer is a French deeptech startup founded in 2020 and headquartered in Pessac, near Bordeaux, that is developing a proprietary biotechnological process to convert organic waste (biodéchets) into biodegradable polymers called PHA (polyhydroxyalkanoates). The company serves industrial customers seeking sustainable, circular-economy-based polymer alternatives to conventional plastics, positioning PHA as a drop-in biodegradable substitute across industrial applications. The underlying technology leverages microorganisms to ferment organic waste streams into PHA, addressing both plastic pollution and organic waste disposal in a single value chain.

The company is currently at a pre-industrialization stage, with no named commercial products, no disclosed pricing, and no reported revenue. Its 2024 operational milestones include reaching pre-industrialization scale, continuing client testing, and initiating pre-orders. The business model is not explicitly disclosed but appears to be a direct B2B model targeting industrial polymer buyers in France and Europe, with a stated ambition to become a leader in circular economy-based polymers in Europe by 2030.

Dionymer raised €1.5 million in seed funding in December 2023 at a €7.5 million post-money valuation from a four-investor French syndicate led by AQUITI Gestion, alongside IRDI Capital Investissement, AFI Ventures, and RESILIANCE. The company operates with a small team of 1-10 employees and has not disclosed management team composition, patents, certifications, or distribution partnerships in the available sources. Information gaps include revenue, named customers, IP filings, leadership profiles, and specifics of the biotechnological process architecture.

Direct peers

• RWDC Industries: Singapore/US PHA producer (Solon) using fermentation of plant oils and sugars. Direct competitor in PHA-based biopolymers, focused on packaging and consumer goods applications.
• Danimer Scientific: US-listed PHA (Nodax PHA) producer and a direct competitor in the biodegradable polymer space. Most directly comparable PHA manufacturer at industrial scale, with established customers in foodservice and packaging.
• CJ CheilJedang (PHACT): South Korean bio-fermentation giant producing amorphous PHA under the PHACT brand. Direct competitor leveraging large-scale fermentation infrastructure, comparable process technology to Dionymer.
• Kaneka Corporation: Japanese chemical company producing PHBH (a PHA copolymer) at commercial scale under the Kaneka Biodegradable Polymer brand. Directly competes in the same PHA chemistry category with global distribution.

Broad incumbents

• NatureWorks: Global leader in PLA (polylactic acid) biopolymers, a major competing biodegradable plastic chemistry. Broad incumbent in bioplastics competing for the same end-use applications (packaging, food service) as PHA.
• TotalEnergies Corbion: Joint venture between TotalEnergies and Corbion producing Luminy PLA bioplastics. Large incumbent producing competing biodegradable polymers, serving the same European customer base as Dionymer's target market.
• BASF (Ecovio / Biopolymers): Global chemical major with Ecovio (PLA/PBAT blend) and other certified-compostable biopolymer offerings. Broad incumbent competing in biodegradable plastics and a potential acquirer/partner for smaller players like Dionymer.

Regional players

• Carbios: French biotech company using enzymatic recycling to depolymerize PET, with broader circular-economy positioning. Comparable as a French deeptech/industrial biotech working on circular polymer solutions, though focused on enzymatic recycling rather than PHA production.

Emerging players

• Newlight Technologies: US-based company producing AirCarbon PHA from greenhouse gases via microbial conversion. Comparable biotech approach to producing PHA from waste streams with circular-economy positioning.
• Mango Materials: US-based startup producing PHA from methane (a waste gas). Comparable emerging biotechnological process converting a waste feedstock into PHA, though using a different waste stream than Dionymer.
