Carbios Under Pressure: Financing Struggles, China Expansion, and a Growing Legal Dispute

Why It Matters

The outcome will shape the viability of enzymatic plastic recycling and determine whether Europe or Asia becomes the launchpad for Carbios’ commercial scale‑up, influencing the broader circular‑economy market.

Key Takeaways

• Longlaville plant delayed due to financing shortfall
• Cash fell to €72 million by mid‑2025
• China JV gives Wankai 70% ownership, guarantees €115 m debt
• Shareholder group ADISECT challenges governance and tech transfer
• Leadership reshuffle replaces founder with new CEO

Pulse Analysis

Carbios has been the poster child of France’s push toward industrial biotechnology, leveraging engineered cutinases to depolymerise PET into its constituent monomers. By converting waste bottles and fabrics back into virgin‑grade polymer, the technology promises a true closed‑loop alternative to mechanical recycling, which degrades material quality over successive cycles. Major consumer brands such as L’Oréal and PepsiCo have already backed pilot programmes, and the company’s 2021 prototype bottles demonstrated food‑grade compliance, positioning Carbios at the forefront of advanced plastic‑recycling innovation.

Despite the scientific promise, Carbios has struggled to translate its lab successes into a commercial reality. The flagship Longlaville plant, designed for 50,000 tons of PET per year, was postponed in December 2024 after the firm failed to secure non‑dilutive financing, and cash reserves slipped to €72 million by mid‑2025. A restructuring announced in early 2025 targeted a 40 % reduction in cash burn, triggering layoffs that could affect up to 40 % of staff. Governance changes followed, with founder Philippe Pouletty exiting and a new CEO, Vincent Kamel, taking the helm.

The December 2025 joint‑venture with China’s Wankai New Materials reshapes Carbios’ growth trajectory, granting the partner 70 % ownership and a €115 million debt guarantee for a 50,000‑ton facility in Zhejiang. While the deal secures near‑term funding and a ready‑made industrial site, it also raises questions about technology sovereignty, as shareholder activist ADISECT argues the partnership jeopardises a strategic French asset. Legal filings from both sides have turned the dispute into a public arena, potentially influencing future financing and licensing arrangements. The outcome will determine whether Carbios can anchor its commercial rollout in Europe or pivot to an Asia‑first model.
