Catalyxx to build €120M renewable chemicals plant at ZILS, Sines
- €120 million investment to develop Catalyxx Iberia at ZILS in Sines.
- Facility will produce butanol, hexanol and octanol from bioethanol.
- Construction is expected to start in Q4 2026 after main environmental approvals were secured.
- Project received €20 million from the Circular Bio‑based Europe JU and is recognised as a Project of National Interest.
Project overview
Catalyxx will develop its first commercial‑scale renewable chemicals production facility, Catalyxx Iberia, at the ZILS – Sines Industrial and Logistics Zone with an investment of about €120 million. The initiative has been recognised by the Portuguese government as a Project of National Interest.
Products and feedstock
The plant will convert bioethanol into butanol, hexanol and octanol to supply low‑carbon alternatives to conventional petrochemical products.
Site selection and infrastructure
ZILS was chosen for its industrial infrastructure, proximity to the Port of Sines, logistics connectivity and access to renewable energy—factors cited as reinforcing Sines’ role for next‑generation industries and decarbonisation value chains.
Timeline, approvals and impact
Main environmental approvals have been secured and construction is expected to begin in the fourth quarter of 2026. The facility is expected to prevent approximately 105,000 tonnes of CO₂ emissions per year and to catalyse new sustainable value chains and further investment in Portugal.
Funding and strategic relevance
Development is supported by private and public funding, including a €20 million award from the Circular Bio‑based Europe Joint Undertaking, aligning the project with European industrial decarbonisation and supply‑chain security objectives.
