With a substantial strategic investment, Haltermann Carless aimed to become the first company to produce Sustainable Aviation Fuels in Germany. The chemical company is now postponing the project for the time being – though its commitment to SAF remains unchanged.

Frankfurt a.M., Germany, 16 April 2025 – Haltermann Carless has been deeply engaged in the development and promotion of Sustainable Aviation Fuels (SAF) in recent years. Central to this commitment was an investment project to produce 60,000 tonnes of SAF annually using the Alcohol-to-Jet (AtJ) process at the company’s production site in Speyer, Germany. The project had progressed to the conceptual design phase.
Despite comprehensive efforts and ongoing dialogue with a broad range of stakeholders from both industry and government in Germany and across Europe, the essential framework conditions and reliable commitments required to advance the project further are insufficient.
“We regret that, under the present circumstances, we are unable to move our SAF-AtJ investment project into the next phase and must therefore place it on hold for the time being,” said Peter Friesenhahn, Chief Executive Officer at Haltermann Carless. He continued: “We remain firmly convinced that Sustainable Aviation Fuels will play a crucial role in shaping a more environmentally responsible future for aviation. That is why we will continue to focus our efforts on developing viable solutions in this important area, close to our company‘s DNA and heritage.”
