Spanish startup Catalyxx, specialized in converting bioethanol into sustainable chemical products, has closed a €3 million funding round led by Axon Partners Group. The investment will be used to drive development of the company’s facility in La Rinconada (Seville), focused on producing renewable chemicals and sustainable aviation fuels (SAF).
The operation is part of the Axon Desarrollo Andalucía fund, managed by Axon with support from the European Investment Bank (EIB) and the Regional Government of Andalusia, reinforcing Catalyxx’s position as one of the most innovative industrial projects in the region.
“Catalyxx is a clear example of the kind of transformative company we aim to support through the Axon Desarrollo Andalucía fund,” said Macarena González, Investment Manager at Axon in Andalusia. “Its technology has the potential to position the region as a European benchmark in sustainable chemistry and the energy transition.”
Proprietary technology with global potential
Catalyxx has developed a patented, non-fermentative process capable of converting bioethanol into biobutanol, biohexanol, biooctanol, and biodecanol—renewable alternatives to fossil-derived products used in paints, adhesives, resins, and cosmetics.
Founded in 2017 by Joaquín Alarcón de la Lastra, a former executive at Abengoa, the company has raised over €18 million in the past year from investors including Aether Chemical Investments, the European Commission’s EIC Accelerator, and now Axon Partners Group.
“This new round allows us to strengthen and continue the development of our technology center in Seville and to consolidate an industrial base from which we can scale our technology globally,” said Joaquín Alarcón de la Lastra, CEO of Catalyxx.
In parallel to its progress in Andalusia, Catalyxx has received pre-approval from the European Investment Bank for a €37 million financing to build its first full-scale industrial plant in France. The FOAK (First-Of-A-Kind) facility will operate alongside a local partner and will use Catalyxx’s proprietary technology to produce renewable biobutanol.
Due diligence is expected to take place in July in Seville, with formal approval anticipated upon successful completion. According to the EIB, this type of technology is essential for advancing Europe’s decarbonization goals and strengthening the shift toward a circular, low-carbon chemical industry.
"This decision by the EIB is a key milestone for Catalyxx and validates our vision to transform the chemical industry through sustainability and efficiency," added Alarcón de la Lastra.
