What's the endgame? The company's patented Algae Forest platform offers low-cost, low-carbon nutrient removal and recovery for smaller municipal and industrial treatment plants. The money will fund commercial deployments, building on its Kingsville demonstration project, which scaled from pilot to full scale.
Why now? More than 10,000 wastewater plants across North America and Europe need upgrades to meet tightening nutrient discharge limits. The US Environmental Protection Agency's 2022–2026 Lagoon Wastewater Treatment Action Plan targets small communities modernizing lagoon treatment, where cost and complexity are the main hurdles.
Nutrient pollution is the leading cause of water quality decline globally. Nitrogen and phosphorus in waterways drive algae blooms, hypoxia, and habitat loss, while both nutrients are increasingly scarce as agricultural inputs — creating demand for recovery and reuse.
AlgaFilm was founded by chief executive officer Ahren Britton, whose team previously helped create the membrane bioreactor category. "The completion of our funding round gives us the fiscal foundation and industry network to support our evolution from technology development to commercial adoption," Britton said.
Investors framed the round as a bet on overlooked infrastructure. "Wastewater infrastructure is one of the most overlooked yet essential opportunities for climate-aligned innovation," said Amy Duffuor, general partner at Azolla Ventures. Steve Kloos, partner at Burnt Island Ventures, said the team "knows how to invent and commercialize wastewater technologies."
The signal: Climate-focused capital is moving toward unglamorous but essential water infrastructure. AlgaFilm's pitch — affordable nutrient recovery for the thousands of lagoon-based plants that regulators are pushing to upgrade — sits squarely at the intersection of tightening rules and rising demand for reusable nutrients.
