Cascadia Seaweed has opened an advanced seaweed processing facility in Port Edward, British Columbia (Canada), completing a multi-year expansion that positions the company as a fully integrated producer of kelp-based crop inputs for North American agriculture.

The new biorefinery will process hundreds of wet tonnes of brown seaweed annually to produce liquid kelp extracts used as biostimulants in crop production. The facility uses chemical-free extraction technology designed to preserve naturally occurring compounds that support plant growth and health.

“This facility represents a significant milestone in building a fully integrated seaweed-based agricultural inputs company in Canada,” says Michael Williamson, CEO and co-founder of Cascadia Seaweed. “We’ve built this business step by step from cultivation through to advanced processing, overcoming the challenges of scaling within this sector. With the facility now operational, our focus shifts toward expanding market adoption and growing our presence in agriculture markets, starting with North America.”

The Port Edward facility marks the completion of Cascadia Seaweed’s Northern Hub, bringing together the company’s operations from kelp farming through final product manufacturing. Founded in 2019, Cascadia Seaweed has developed farming partnerships with Coastal First Nations and built processing infrastructure to maintain control over product quality and bioactivity.

The project was developed in partnership with Metlakatla Development Corporation and received support from NorthX, the National Research Council of Canada, Agriculture and Agri-Food Canada, the Province of British Columbia, and private equity partners.

With its production infrastructure now established, Cascadia Seaweed plans to focus on commercial expansion across North America, targeting growers looking to optimize crop production inputs.
