Solving the PFAS crisis at scale—without creating another environmental liability down the line.
We envision a future where all people have access to contamination-free water. Achieving that vision requires a fundamental departure from typical modern remediation methods. We refuse to exchange chemical water pollution for petroleum dependence or microplastic accumulation. Sequestro engineers advanced, bio-renewable adsorbents that deliver absolute environmental protection without compromise.

Doing the right thing, the right way.
We believe in combining rigorous material science with genuine human responsibility. These five core principles guide our company culture and our environmental
People

Integrity
Do the right thing, the right way—no shortcuts.
Sustainability
Strive to leave the planet a better place than we found it—we owe it to our children.
Philanthropy
Invest in the next generation through active mentorship and continuous R&D.
Products
Enable modern conveniences by designing premium-quality products that reliably solve real problems.
From fundamental chemistry to industrial scale-up.
ArborSORB™ is not a speculative startup concept. It is a highly validated technology built upon years of rigorous molecular innovation and institutional execution.
The Molecular Breakthrough
Foundational macromolecular research at the University of Michigan discovers that cellulose fibers functionalized with specific cationic amines could selectively bind anionic PFAS. The technology is rigorously peer-reviewed and published in ACS ES&T Water, demonstrating greater than 80–90% removal efficiencies of PFOA and PFOS within a 30-second contact time.
Corporate Spinout
Sequestro, Inc. is officially incorporated and established in Ann Arbor, Michigan, securing the exclusive global intellectual property rights to commercialize the platform out of the University of Michigan research ecosystem.
Market Validation & Optimization
Sequestro secures a $50K National Science Foundation (NSF) I-Corps grant, executing 150+ structured customer interviews with municipal operators and environmental firms to validate market fit. Simultaneously, a $40K U-M ADVANCE Proof-of-Concept grant, administered through Michigan State, enables the successful transition of the core synthetic chemistry from processed pulp to raw, upcycled forestry sawdust.
Infrastructure Scale-Up
Sequestro has secured $692,500 in pre-seed venture investment, with all participating investment firms and angel investors based in Michigan, reflecting strong support from the state’s innovation and entrepreneurial ecosystem. The company also secured a $250,000 NextCycle Michigan Circular Economy grant to support a pilot engagement in Michigan.
Operations have moved into an advanced laboratory space at 600 S. Wagner Road, where Sequestro is commissioning a 20L scale-up reactor facility to generate uniform media batches for independent column testing ahead of field pilot execution.
Driven by domain expertise.
Sequestro is built by pioneering environmental chemists and macromolecular engineers explicitly equipped to translate laboratory breakthroughs into industrial-scale solutions.
