PolyGone rolls out water analysis service, signs commercial customers, and prepares to deploy PolyPod™ systems able to treat 10 million gallons of water per day for microplastic pollutants

PolyGone Systems, a Princeton University spinout focused on microplastic monitoring and removal, announced today that it raised a $4 million Seed round led by FYRFLY Venture Partners, with participation from Tech Council Ventures, Interstate Fusion Ventures, Golden Seeds, and angels. The New Jersey Innovation Evergreen Fund matched $1.65 million of the raise. In parallel, PolyGone formally launched its microplastics analysis service, offering accurate and affordable water testing for the public, private companies, and government utilities, helping them better understand exposure risks and compliance needs.

Founded in 2021, PolyGone develops patented filtration systems that remove 98% of toxic microplastics from water at a 90% lower cost than alternative methods. The company operates a wastewater removal pilot for the Atlantic County Utilities Authority (ACUA) and has already signed three new commercial deployments in 2026 with plans to expand within the municipal treatment, industrial water, and food and beverage markets.

With the Seed funding, PolyGone will produce and deploy its first commercial municipal PolyPod™ systems, designed to treat up to 10 million gallons of water per day for microplastic pollutants. It will also launch a new inline PolyCartridge™ filtration system for industrial water streams.

“Microplastics are not only the most pervasive contaminant in our waters, but the most misunderstood,” said Nathaniel Banks, CEO of PolyGone Systems. “This funding allows us to build the infrastructure needed to monitor microplastics across industrial, municipal, and community settings while scaling an ecosystem of filtration technologies.”

“PolyGone is on the path to creating a proprietary data and intelligence source that becomes critical to solving the global microplastics crisis,” said Julie Maples, Co-Founder and General Partner at FYRFLY Venture Partners. “PolyGone will be a must-have partner for water authorities that protect public health and for industrial companies that face increasing public and regulatory pressure to rein in microplastics pollution.”
