We are a material sciences and technology company that develops High-Affinity Cyclodextrin Polymer (HACP) adsorbents that remove hazardous micropollutants from drinking water. 
Our High-Affinity Cyclodextrin Polymer (HACP) adsorbents are sustainably made from corn-based sugar molecules called “cyclodextrins,” and selectively target micropollutants at concentrations below one part per billion, resist fouling by inert materials in water, and offer instant uptake capability with low dosage requirements. These unique features make our HACPs ideally suited for use in industrial, municipal, and consumer flow-through water treatment systems that serve businesses, communities and households.
Derived from corn, our HACP adsorbents use a renewable resource to remove pollutants from the environment.
The novelty of our technology is to organize naturally “sticky” cyclodextrins into highly adsorbent networks, with porous, crosslinked pathways through which thousands of micropollutants are adsorbed within 0.78 nanometer cyclodextrin cups. The crosslinked pathways provide additional affinity for more rapid attraction of pollutants, and can be tuned to target specific contaminants through modification of the monomer to have greater association with the chemical properties of the contaminant.

Community water treatment facilities are ineffective against most micropollutants.


Because they exist at trace concentrations, micropollutants pass through the municipal water treatment plants that supply tap water to over 85% of the U.S. population. As a result, households are being exposed to these chemical contaminants through their drinking water.

Today, perfluorooctanesulfonic acid (PFOS), a micropollutant linked to cancer, endocrinological disorders, and developmental disorders, is already found in the blood serum of 97% of Americans. Responding to the threat of micropollutants presents a major challenge to municipalities responsible for providing safe drinking water to the communities they serve.
Clear water does not mean clean water. We can no longer take safe drinking water for granted.

Clean, safe drinking water is indispensable for healthy communities, economies, and ecosystems. Unfortunately, a new class of hazardous contaminants called micropollutants have been identified in drinking water systems in the U.S and around the world.

Classified as “micropollutants” because of their extremely low  concentrations in water (on billionth of a gram or less per liter of water), they include pesticides, pharmaceuticals, hormones, and industrial chemicals. A growing number, including perfluorinated compounds (PFOA, PFOS), are linked to various cancers, brain and nervous system damage, developmental defects, fertility problems and endocrine disorders.
