en.Wedoany.com Reported - Topsoe and Swedish refiner Preem have successfully completed a co-processing activity at Preem's Gothenburg refinery, producing renewable diesel and sustainable aviation fuel.

The trial utilized waste- and residue-based lipids blended with traditional refinery feedstocks, demonstrating the flexibility of existing hydrotreating units in large-scale production of low-carbon fuels. This co-processing run is part of Preem's long-term plan to increase renewable fuel output and reduce the carbon intensity of its overall product portfolio. Topsoe provided its HydroFlex technology, enabling the refinery to integrate bio-based feedstocks without extensive modifications to infrastructure. Both companies confirmed that the produced fuels meet specifications for road transport and aviation use.

Preem stated that the trial supports its strategic goal of becoming the leading renewable fuel producer in Scandinavia. The company, which aims to achieve net-zero emissions by 2035, is currently evaluating further upgrades to expand dedicated renewable fuel capacity. Topsoe noted that co-processing offers refineries a fast and capital-efficient pathway to scale up renewable fuel production, while long-term standalone biorefinery projects are also advancing. This achievement highlights the growing importance of refinery integration in accelerating Europe's supply of HVO and SAF.
