A cutting-edge, energy-efficient wastewater treatment solution seeks to promote sustainability within the seafood sector
WALLA WALLA, Wash. , Dec. 11, 2025 — Perca, Inc. has initiated a pioneering trial employing vermifiltration technology to process wastewater from seafood operations—particularly shrimp production. This initiative showcases a novel, nature-inspired method for wastewater management that supports the seafood industry’s increasing emphasis on sustainability, energy conservation, and prudent resource stewardship.
The initiative receives partial grant funding and unites a partnership of industry and environmental experts, such as Angee Hunt from the Oregon State University Seafood Research and Education Center, Lori Steele from the West Coast Seafood Processors Association, Tim Greseth from the Oregon Wildlife Foundation, Russ Davis from Perca, Inc., and Andrew Bornstein from Bornstein Seafoods.
Leveraging Natural Processes for Purified Water
Vermifiltration employs earthworms and advantageous microorganisms to organically decompose waste materials in wastewater. In contrast to traditional mechanical or chemical treatment systems, vermifiltration demands minimal energy consumption and generates few to no chemical residues. This method converts waste into recyclable water and nutrient-dense secondary products, providing an eco-friendly answer that serves both processing facilities and local ecosystems.
“This innovation replicates nature’s most effective processes,” stated Russ Davis, CEO of Perca, Inc. “Utilizing worms and microorganisms to purify seafood wastewater enables us to cut energy use, lessen environmental effects, and develop a circular system that fosters improved coastal ecosystems.”
A Partnership-Driven Strategy for Progress
The pilot study is being carried out in collaboration with Bornstein Seafoods in Astoria, where scientists and industry collaborators are evaluating how well vermifiltration handles shrimp processing effluent—a demanding, nutrient-dense wastewater flow. The findings will assist in assessing the technology’s potential for broader application across various seafood processing activities.
“Teamwork is central to this endeavor,” remarked Angee Hunt of the OSU Seafood Research and Education Center. “By merging scientific investigation with practical industry knowledge, we’re discovering fresh approaches to render seafood processing more hygienic, sustainable, and robust.”
Lori Steele, Executive Director of the West Coast Seafoods Processors Association, added, “This initiative demonstrates the sector’s dedication to funding advancements that serve both commercial interests and ecological well-being.”
Advancing Toward an Eco-Friendly Seafood Industry
Vermifiltration shows potential beyond shrimp processing, extending to numerous seafood industry uses. Its minimal operating expenses, reduced energy requirements, and biological treatment approach establish it as a feasible framework for coastal facilities pursuing both ecologically sound and financially sensible wastewater management options.
“Safeguarding Oregon’s water resources and wildlife begins with forward-looking ideas,” noted Tim Greseth, Executive Director of the Oregon Wildlife Foundation. “Initiatives such as this illustrate how cooperative efforts among scientific, industrial, and conservation communities can produce significant ecological advancements.”
