PolyGone Systems partners with Enduring Planet to remove microplastics from sensitive water systems

74% Removal rate
3 Ongoing pilot projects
250K+ Residents benefitted

PolyGone Systems is a Princeton University spinout cleantech company with a mission to remove the trillions of potentially harmful microplastics entering the world's oceans and drinking water. Microplastics are now considered an emerging aquatic pollutant, yet no systems can affordably and systematically remove them before they enter broader aquatic environments and drinking water sources. Polygone has developed a biomimetic filtration system, the Artificial Root, which is designed to remove microplastics from wastewater treatment effluent channels, drinking water treatment channels, open streams, river mouths, marinas and lake outflows.

Polygone's products include a modular filtration system and a floating supporting pontoon, which can be easily accumulated to adapt to a wide range of water channels. They also provide microplastic monitoring report services to help water system managers find the best-suited remediation options for targeted waterways.

The Polygone filter removes 74% of microplastic particles introduced to a controlled flow tank. Currently, they are building the world's first microplastic removal pilot project at the Atlantic County Utility Authority, which serves 200k residents.

Polygone contributes to SDG 12 (Responsible Consumption and Production) and SDG 14 (Life on Water).

PolyGone Systems partnered with Enduring Planet to:

  • Alleviate cash flow stress
  • Support on-going design development for the pilot project

Maintaining momentum without cash flow stress

The protracted process of initiating grant awards often leaves many small businesses grappling with insufficient cash flow to sustain ongoing innovation while awaiting funding disbursement. The Enduring Planet Grant Advance enabled Polygone to maintain momentum without the burden of cash flow concerns during the Grant pre-funding period.

The team at Enduring Planet is efficient, diligent and capable.
