San Diego Business Journal reported on Cyclopure Inc., a San Diego-based water purification company that developed cyclodextrin technology licensed from Cornell University. The technology helps to filter out nanoscale levels of hazardous per- and polyfluorinated alkyl substances and other micropollutants from drinking water.
The four-year old company connects beta-cyclodextrins from WACKER with rigid crosslinking monomers to produce a powerful water-purifying and health-saving adsor-bent that removes micropollutants. Tackling a global health problem per- and polyfluorinated alkyl substances (PFAS), highly toxic type of micropollutants, have emerged as an urgent global health concern. Composed of thousands of compounds, the chemicals have made their way into groundwater from a wide range of industry applications such as firefighting foam, packaging, textiles and non-stick pans. Moreover, the chemicals have been detected in the air, soil, plants, humans, wildlife and aquatic environments.
The team aims to take their technology into several markets. There is the consumer point-of-use market (think of home systems that use carbon to purify water). The company plans to sell branded products through its e-commerce website. In parallel with commercialization of the first generation of water treatment products, the company continues to invest heavily in research and development to improve the performance and value of its cyclodextrin adsorbents. Cyclopure’s scientists have modified their cyclodextrin adsorbents to target specific contaminants. After targeting pharmaceuticals and pesticides with its technology, the company’s chemists designed a second adsorbent named, DEXSORB+ and will be used for municipal applications. Today, its pilot scale production at the lab is producing 60 kilograms per month, enabling them to push out its commercial products, analytical and home activities. Next month in July, the company is launching its second home water test kit for pharmaceuticals and pesticides.
Cyclopure is working with several partners in the U.S. and Europe both in drinking water and wastewater treatment projects. Notable municipal partners include Orange County Water District, Rahway Water (NJ), and Aqua America (PA) among others. In total, Cyclopure has raised $10 million in funding, including a $3.5 million Series A round and Small Business Innovation Research grants from the National Science Foundation and National Institute of Environmental Health Sciences. The company was founded in 2016 by Cassou and Will Dichtel, a chemistry professor with Northwestern University. Headquartered in Encinitas, the startup now employs 15 after recently adding five additional staffers to its team.
