About

Founded by Amelia Thomas and WPI Professor Michael Timko, River Otter Renewables’ ECLIPSE system uses radical hydrothermal liquefaction to break down PFAS—the toxic “forever chemicals” found in firefighting foams—converting waste into reusable water and renewable oil.

Proven to remove 99.9% of PFAS within minutes, the technology is attracting government and industry contracts. River Otter is redefining waste management as a clean-energy opportunity.
