Sequestro develops ArborSORB, a sawdust-based adsorbent intended to capture a range of PFAS molecules from drinking water and industrial water streams. The technology builds on research from University of Michigan professor Anne McNeil and was commercialized by founder Juergen Koller in July 2024. The company positions ArborSORB as a bio-renewable, lower-cost alternative to engineered filter media, sourcing sawdust as a waste-to-resource feedstock. Sequestro is targeting technical industrial customers with PFAS challenges and plans pilot programs to validate performance under real-world water chemistries. Its near-term financial plan relies on pre-seed commitments—over $700,000 total with a $150,000 investment from Ann Arbor SPARK—to fund those pilots. Management aims to complete customer testing and secure partnership opportunities that enable later commercialization and scale by the end of 2027.
