In a significant step toward advancing carbon capture innovation, BASF SE and the ANDRITZ Group have signed a license agreement for the use of BASF’s proprietary OASE® blue gas treatment technology. ANDRITZ and BASF will apply the technology in a large-scale carbon capture project in Aarhus, Denmark. The project supports the city’s goal of becoming CO₂-neutral by 2030.
Capturing 4,35,000 Tons of CO₂ Annually
The project is designed to capture approximately 435,000 tons of CO₂ per year from the flue gases of a waste-to-energy plant. The captured emissions will then be stored through sequestration. ANDRITZ, the selected supplier for the carbon capture plant, is currently conducting pre-engineering work. The final implementation of the project depends on the customer securing funding. This funding must come from the Danish CCS (Carbon Capture and Storage) fund.
Leveraging Proven OASE® Blue Technology
As a supplier of complete carbon capture plants, ANDRITZ chose OASE® blue for its proven performance, reliability, and efficiency. The decision draws on BASF’s decades of chemical expertise and extensive track record in gas treatment applications. The project addresses one of the key challenges in carbon capture — meeting stricter emission limits for post-combustion capture units. As environmental regulations tighten, flue gas compositions are becoming increasingly complex. BASF’s technology provides the flexibility and robustness needed for these demanding applications.
Industry Leaders Highlight Collaborative Strength
“We are excited to partner with BASF on this important carbon capture project in Aarhus,” said Klaus Bärnthaler, Vice President at ANDRITZ Clean Air Technologies. “This collaboration reflects our commitment to offering innovative and tailored carbon capture solutions. By combining our plant engineering expertise with BASF’s deep chemical knowledge, we are well-positioned to support sustainable waste management and advance decarbonization efforts.”
Vasilios Galanos, Senior Vice President Europe, Intermediates division at BASF, noted, “From the outset, our collaboration with ANDRITZ has demonstrated the power of combining engineering precision with chemical innovation. Together, we have developed effective solutions to overcome complex emission challenges. This project underscores the versatility of OASE® blue and reaffirms our commitment to delivering sustainable gas treatment solutions for the waste-to-energy sector.”
OASE® Blue: Supporting Cleaner and More Efficient Operations
BASF’s OASE® technology portfolio has established itself as a global leader in gas treatment, operating in more than 500 reference plants worldwide. The OASE® blue system offers lower energy consumption, reduced solvent losses, and enhanced process flexibility. It also ensures minimal impurities in both the treated gas and the captured CO₂. Its robust design makes it particularly suited for tackling flue gas impurities from fossil power plants, steam reformers, and boilers. It is also effective for waste incineration units and the cement industry—sectors where decarbonization remains a critical challenge.
Driving the Path Toward Carbon Neutrality
Through this collaboration, BASF and ANDRITZ are not only pioneering next-generation carbon capture technologies but also supporting Denmark’s national climate goals. According to the company press release, the partnership combines engineering excellence and chemical innovation. It demonstrates how strategic technology alliances can accelerate the transition toward a low-carbon future. It also helps industries capture, reuse, and reduce CO₂ emissions at scale.
