Seville-based Catalyxx has announced plans to construct a €120 million commercial-scale production facility in Sines, Portugal. This significant investment aims to transform bioethanol into renewable alternatives for fossil-derived industrial chemicals. The new plant, Catalyxx Ibérica, marks a pivotal step in advancing Europe's circular bio-based economy and reducing industrial carbon emissions.


Strategic Location and Investment

The selection of Sines is strategic, leveraging one of Europe's premier industrial and logistics hubs. The site offers world-class infrastructure, a deep-water port, and crucial access to renewable energy sources. These advantages will bolster Catalyxx's mission to enhance supply chain security and promote decarbonization within the European chemical sector.

The project's development is backed by a blend of private investment and substantial public funding. A key component of this financing is a recent €20 million award from the Circular Bio-based Europe Joint Undertaking. This grant underscores the project's strategic importance in strengthening Europe's industrial sustainability and competitiveness on a global scale.

Innovative Technology and Products

Catalyxx utilizes a proprietary catalytic process to convert bioethanol into butanol, hexanol, and octanol. These products are designed as "drop-in" chemicals, meaning they are chemically identical to their petrochemical counterparts. This allows industrial customers to adopt these sustainable materials without modifying their existing equipment or production processes.

The bio-based chemicals produced will serve diverse industries, including coatings, adhesives, plastics, and personal care products. By offering a lower-carbon alternative, the Sines facility is projected to prevent approximately 105,000 tonnes of CO₂ emissions annually. This contributes significantly to the climate goals of its industrial partners and the region.

Project Development and Government Support

The project is currently in its final development phase, with construction scheduled to commence by the fourth quarter of 2026. Engineering activities are being managed by global experts Worley and leading consultancy Quadrante, ensuring industrial readiness. This commercial scale-up builds upon extensive validation and data collection at the company's demonstration plant in Seville.

Recognizing its strategic value, the Portuguese Government has designated the facility a Project of National Interest (PIN). This status provides an accelerated regulatory approval process, streamlining the path to construction. The project has already secured its main environmental approvals, marking another critical milestone toward its realization.

A Step Towards a Greener Chemical Industry

According to CEO Joaquín Alarcón, the facility embodies the company's mission to replace fossil-based chemicals with renewable, low-carbon alternatives. He expressed gratitude for the support from Portuguese authorities, highlighting the project's dual role in defossilizing the industry. The initiative is also set to position Portugal as a European leader in sustainable industrial innovation.

Founded in 2017, Catalyxx has focused its research and development activities at its technology center in Seville, Spain. The company has successfully proven its technology under continuous operating conditions at its demonstration plant. The Sines facility represents the crucial transition from successful validation to full-scale commercial manufacturing and global expansion.


The establishment of the Catalyxx Ibérica plant in Sines is a landmark achievement for the bio-based chemical industry. This €120 million facility will not only reduce industrial reliance on fossil fuels but also enhance European supply chain resilience. Ultimately, the project serves as a powerful model for scaling sustainable manufacturing and driving the transition toward a circular economy.
