Synovance: EIC Accelerator Bio-Dye Maker Ends in Liquidation
The blue of almost every pair of jeans comes from synthetic indigo, made from oil-derived chemicals. Synovance, founded in 2017 in Bry-sur-Marne east of Paris, set out to make the same molecule with engineered bacteria fed on sugar and waste biomass: identical dye, no oil, no toxic intermediates.
The European Innovation Council granted €1,947,888 towards a €2.78 million project to scale that production. According to the French court record, Synovance stopped being able to pay its debts on 1 August 2024, six months before the project ended. It entered receivership on 9 July 2025 and was placed in liquidation on 22 July 2025.

What Happened to Synovance
The registers Pappers and Societe.com record the sequence. The court opened receivership (redressement judiciaire) on 9 July 2025 and fixed the cessation of payments at 1 August 2024. Thirteen days later, on 22 July 2025, it converted the case into liquidation, the route French insolvency law reserves for cases where recovery is manifestly impossible. The liquidator's statement of creditors' claims was filed on 14 September 2026. Synovance's accounts had been filed confidentially, so the size of its debts is not public.
The Technology: Dyes From Microbes
Synovance's method, as described on CORDIS, was to use computational and genomic tools to engineer bacteria that turn sugar, salts and waste feedstocks into dye molecules, then purify them into products "aniline-free and environmentally friendly" with the same dyeing performance as synthetic dyes. Aniline, a toxic chemical, is a starting material in conventional synthetic indigo. The company's own materials, reported by the textile press, claimed its bio-based dyes emitted ten times less CO2 than conventional synthesis.
The approach is not unique: Sourcing Journal has covered several start-ups pursuing bio-based dyes. Synovance's distinctive claim was its "Synthetic Genomics Platform", which the project report says cut both the time and cost of developing production strains more than tenfold.
What the EIC Project Promised, and What CORDIS Shows
The EIC project
The EU paid 70% of a €2.78M dye project
NextGen Dyes ran from February 2022 to January 2025.
CORDIS project 190199874. Values in € millions.
NextGen Dyes ran from 1 February 2022 to 31 January 2025. The objective said the company would sell indigo blue first to dyeing houses and fabric makers, then a full range of colours, and claimed its "top-seller sustainable dye" already held a 50% market share, a figure given without any indication of which market. The final report, updated on 23 May 2025, describes an integrated pilot plant, then a larger demonstration facility for continuous operation, and the strain-engineering platform. It reports no sales, customers or production volumes, and it does not mention the insolvency, which the court only dated to August 2024 in July 2025, after the report.

The timing
Six months of the EIC project ran after insolvency began
Months between the court-fixed cessation of payments (1 August 2024) and each event. The project kept running until January 2025.

The Sequence
The record
Insolvent before the EIC project ended
The court set the cessation of payments six months before the project's end date. The EU's report on the project, updated in May 2025, does not mention it.

What the public cannot see
The court record, issued in July 2025, fixes Synovance's cessation of payments six months before the end of an EU-funded project; the report published in May 2025 describes the project as completed with positive results. Whether the final grant payment was made, and what the creditors, including any public ones, will recover, are not public. The liquidation file may answer some of that.
Why Europe Should Care
A European, bio-based source of the world's most used denim dye would reduce dependence on petrochemical supply chains. That makes Synovance's failure worth studying: the EIC backed a relevant technology, and the company still ran out of money before it could sell at scale.
What the project promised
Oil-free, non-toxic textile dyes made by microbes, starting with indigo and scaling to a full colour range.
What the record shows
A pilot and demonstration facility, no published sales, insolvency during the project and liquidation six months after it ended.
The Verdict
A technical project, a failed company
Synovance may well have made the technical progress its report describes. It did not survive to use it. The closing summary reads as a success. It was published in May 2025, before the court's July 2025 ruling, which fixed the start of the insolvency almost ten months earlier.
Synovance and its liquidator have not been asked for comment for this article. It is based entirely on public records and EU project data, linked throughout.
