BASF and ANDRITZ Sign License Agreement For OASE® Technology
24 October 2025, Germany: BASF SE (BASF) and ANDRITZ Group have signed a license agreement for the use of BASF’s proprietary gas treatment technology, OASE® blue, in a carbon capture project planned to be implemented in the city of Aarhus, Denmark. The project aims to capture approximately 435,000[1] tons of CO2 annually from the flue gases of a waste-to-energy plant for sequestration; the city of Aarhus has set itself the goal of becoming CO2-neutral by 2030. ANDRITZ, the selected supplier for the carbon capture plant, is currently conducting pre-engineering. The project’s implementation is contingent upon the customer receiving funding from the Danish CCS fund.
As a supplier of complete carbon capture plants, ANDRITZ selected the proven OASE blue technology based on BASF’s extensive track record and deep chemical expertise. This expertise is needed because of the increasing focus on emission limits for post-combustion carbon capture units, where evolving regulations and complex flue gas compositions pose significant challenges.
“We are excited to partner with BASF on this important carbon capture project in Aarhus. This collaboration reflects our commitment to providing innovative carbon capture solutions tailored to customers’ needs. By combining our plant engineering know-how with BASF’s chemical expertise, we are well-positioned to support sustainability in waste management,” said Klaus Bärnthaler, Vice President at ANDRITZ Clean Air Technologies.
“From the very beginning, our collaboration with ANDRITZ has been marked by a strong partnership between engineering and chemical expertise. Together, we identified effective solutions to address the project’s complex emission challenges. This project underscores the strength of our continued engagement in the waste-to-energy sector, highlights the versatility of OASE blue, and reinforces our commitment to delivering sustainable gas treatment solutions,” added Vasilios Galanos, Senior Vice President Europe, Intermediates division, BASF.
With the OASE portfolio, BASF is a leader in gas treatment technology, which is used in over 500 reference plants worldwide. OASE blue, one of BASF’s gas treatment technologies, is designed to support customers in achieving lower energy consumption, reduced solvent losses, high flexibility and minimized impurities in both the treated gas and the CO2 product. This technology is particularly suitable for the special challenges posed by impurities in flue gases from fossil power plants, steam reformers, boilers, waste incineration plants and in the cement industry.
