Founded in 2021 out of Princeton University, PolyGone Systems develops patented filtration systems that remove 98% of toxic microplastics from water at 90% lower cost than existing alternatives. Its flagship PolyPod™ units are engineered to treat up to 10 million gallons of water per day, targeting municipal wastewater facilities. Complementing the hardware, the company has launched a microplastics analysis service that provides affordable testing for public agencies, private companies, and utilities to assess contamination and regulatory compliance. PolyGone is currently running a wastewater pilot with the Atlantic County Utilities Authority and has signed three additional commercial deployments slated for 2026 across municipal, industrial, and food-and-beverage customers. Near-term plans include mass production of the PolyPod™ systems and the release of an inline PolyCartridge™ filter for industrial water streams. Management positions the company as a future proprietary data and intelligence provider on microplastic pollution, aiming to become indispensable to water authorities and industrial operators.
