How Perca’s vermifiltration trial could spark a sustainability revolution in seafood processing

Perca, Inc., a cleantech firm based in Walla Walla, Washington, is taking a page from nature’s playbook to tackle one of the seafood sector’s most persistent challenges: wastewater generated from shrimp processing. Announced on December 11, 2025, Perca’s new trial deploys earthworm-driven vermifiltration at a Bornstein Seafoods facility in Astoria, Oregon, aiming to convert high-strength organic waste into reusable water and nutrient-rich byproducts with minimal energy input.

The project brings together a coalition of environmental and industry leaders, including Angee Hunt of the Oregon State University Seafood Research and Education Center, Lori Steele of the West Coast Seafood Processors Association, Tim Greseth of the Oregon Wildlife Foundation, Russ Davis of Perca, Inc., and Andrew Bornstein of Bornstein Seafoods. The effort is partially grant funded, reflecting broad support from both the conservation and business communities.

How does vermifiltration technology work, and why is it different from traditional wastewater treatment in seafood processing?

Vermifiltration is built around a remarkably simple yet powerful idea: let earthworms and naturally occurring microbes do what they do best. By passing wastewater through specially engineered beds populated by worms and beneficial microorganisms, organic contaminants are rapidly broken down and digested. Unlike conventional mechanical or chemical treatments that rely on energy-hungry machines or complex chemical processes, vermifiltration is gravity-driven, requires little external energy, and eliminates most chemical byproducts.

Russ Davis, CEO of Perca, Inc., has attributed the innovation’s appeal to its ability to close the loop on seafood waste, reducing both energy consumption and environmental impact. He emphasized that the technology replicates nature’s innate filtration processes, allowing shrimp processing plants to transform their most problematic byproducts into valuable resources—clean water and nutrient-rich compost.

Not only does the process reduce operational costs, but it also supports broader sustainability targets for coastal industries under pressure to reduce their environmental footprints. With new ESG benchmarks and regulatory scrutiny rising for food processors, solutions like Perca’s DrilO2 system are drawing industry-wide interest.

Who are the key partners behind the Astoria pilot, and how are they shaping the future of sustainable seafood processing?

This trial is more than just a technology demo—it is a collaborative research effort involving some of the most respected names in Pacific Northwest seafood and conservation. Bornstein Seafoods is hosting the trial, providing a real-world testbed for vermifiltration under actual shrimp processing conditions. Oregon State University’s Seafood Research and Education Center brings scientific rigor and measurement to the project, while the West Coast Seafood Processors Association and the Oregon Wildlife Foundation offer industry and conservation perspectives.

Angee Hunt of Oregon State University has highlighted the importance of bridging academic research with practical industry challenges, arguing that partnerships like these can drive innovation that is both commercially viable and environmentally responsible. Lori Steele, representing the seafood processors, noted that the sector’s willingness to back such projects signals a broader shift toward innovation-first thinking in seafood supply chains.

Tim Greseth of the Oregon Wildlife Foundation has described the pilot as an example of how targeted partnerships between science, industry, and advocacy can translate into measurable environmental gains—especially in a state where water quality and wildlife are deeply connected to the health of local industries.

What makes Perca’s DrilO2 system a viable model for budget-stretched water utilities and seafood processors alike?

The DrilO2 system at the heart of the trial has already proven itself in other municipal and industrial settings. Unlike conventional wastewater plants, which often demand heavy capital investment and ongoing energy and chemical costs, DrilO2 uses earthworm-based biology to dramatically cut expenses and simplify operations.

According to Perca’s R&D manager Geraldine Case, the biggest advantage for utilities and food processors is the system’s low barrier to entry. With aging infrastructure and regulatory pressure mounting, communities and businesses are looking for upgrades that don’t break the bank. By offering a gravity-fed, modular approach, DrilO2 allows for incremental investment and lower maintenance, making it an attractive solution even for smaller processors or municipalities struggling with budget constraints.

The technology also reduces the need for constant operator oversight, chemical dosing, and frequent maintenance, providing more consistent performance with fewer headaches. This budget-friendly footprint makes advanced water treatment accessible to processors who previously found such investments financially prohibitive.

Dr. George Damoff, Perca’s Chief Science Officer, has explained that DrilO2 is engineered to harmonize with nature while delivering high-efficiency water purification. He pointed out that the result is not just cleaner water but also a significant reduction in carbon emissions and overall environmental impact—a key selling point for processors aiming to align with sustainability frameworks and secure future market access.

Why is the seafood sector betting on nature-based wastewater treatment—and what does it mean for broader industry sustainability?

Seafood processors have faced mounting scrutiny over wastewater management, especially as the environmental consequences of untreated organic waste become harder to ignore. With coastal ecosystems under pressure, regulators, customers, and advocacy groups have increasingly demanded that the sector find practical, scalable solutions.

By launching this trial, Perca and its partners are signaling a willingness to embrace nature-based innovation as a core part of their environmental and economic future. The low operational and energy costs of vermifiltration, combined with the potential for nutrient recovery and water reuse, offer an appealing path forward for seafood firms aiming to reduce both regulatory risk and real-world costs.

Analysts tracking sustainable infrastructure see projects like Perca’s as early markers of a larger trend, where circular economy principles and ecological engineering begin to outcompete purely mechanical or chemical alternatives. For seafood processors with shrinking margins and tightening compliance standards, the promise of a greener, cheaper, and more resilient solution is a powerful incentive.

What does the future hold for vermifiltration technology in seafood and beyond—and what are investors and industry leaders watching?

With the trial still underway, attention will focus on scalability, reliability, and the ability to adapt vermifiltration to different waste streams across the broader food sector. Should results meet expectations, Perca’s technology could see rapid adoption not just in shrimp processing but across a host of seafood and agricultural applications.

Investors and sustainability-focused funds are watching closely, as solutions like DrilO2 offer a rare convergence of cost reduction, regulatory compliance, and ESG credentials. The potential for wider industry adoption—especially in export-driven seafood regions facing stricter environmental oversight—means that a successful outcome in Astoria could set a template for replication globally.

In my view, the pilot’s most interesting angle is the realignment it represents: rather than fighting nature, food processors are leveraging its inherent strengths. If earthworms can deliver the goods at scale, we may soon see a new standard emerge for wastewater management—one where biological systems take the lead, and energy bills and environmental liabilities take a welcome dive.
