[VIDEO] Transforming industrial side streams with tangential ultrafiltration.

In the shift towards a circular bioeconomy, valorizing industrial side streams is key to reducing waste and unlocking new resources. At CIRCALGAE, we are exploring tangential ultrafiltration (TUF) as a powerful tool to selectively eliminate salts and concentrate high-value compounds, particularly from algae-based industrial processes.  

But, why Tangential Ultrafiltration?  

• Selective Separation: TUF removes unwanted salts while preserving bioactive compounds.  

• Sustainable processing: enhances resource recovery and minimizes waste discharge. 

• New market opportunities: TUF enables the extraction of proteins, pigments and other bioactive compounds from underutilized streams.  

• Scalable for industry: TUF can be implemented from pilot to full-scale production, adapting to different process needs.  

At CIRCALGAE, we are applying this technology to harness the full potential of algae-derived compounds, paving the way for innovative applications in food, cosmetics, and nutraceuticals. The future of industrial processing is smarter, cleaner, and circular—and membrane technologies like TUF are helping us get there.
