Seaweed

A plastic cup can take minutes to use and centuries to disappear. Yet the material that makes it possible still comes largely from one of the world's most valuable finite resources: oil. The same dependence runs through countless products and supply chains, leaving businesses exposed whenever commodity prices surge, trade routes fracture, or access to a critical input tightens.

COVID-19 made that exposure impossible to ignore. Factories stalled, shipping networks buckled, and companies discovered how little control they had over inputs produced thousands of miles away. According to John Soukas, CEO and Co-Founder of Norfolk Green Ventures, the lesson points toward a resource that could give industry another feedstock: seaweed.

"We don't need to replace, we need to complement," Soukas says. "The world is heavily dependent on fossil fuels, and this is not meant to replace fossil fuels. It's meant to provide industry with an alternative. If we can open the door to other inputs, something like seaweed gives businesses another option and makes supply chains more resilient."

Calling seaweed a sustainable resource undersells the commercial proposition, with Soukas calling seaweed "nature's unicorn". Its potential reaches into bioplastics, textiles, inks, dyes, agricultural biostimulants and food. He explains how one crop could feed several markets, allowing demand in one sector to help build the infrastructure required by another.

Soukas likens the opportunity to soybeans decades ago, except with a far broader industrial canvas. "It's like soybeans 60 or 70 years ago, but on steroids," he says. "You have all these other applications, and they complement each other. The bigger those markets get, the greater the opportunity to scale and reduce costs."

That ability to serve several industries at once could be crucial. Soukas notes that a new industrial feedstock needs demand large enough to justify investment in processing, logistics, and production. Seaweed potentially arrives with several sources of demand already attached.

Its resource requirements sharpen the proposition. Seaweed does not need freshwater, agricultural land, or fertilizer to grow. At a time when droughts are putting pressure on farming communities and freshwater reserves, a feedstock that grows in the ocean carries an economic advantage that has little to do with its environmental credentials.

Soukas sees the same logic extending into energy. Oil remains extraordinarily useful, yet its use in short-lived products raises a basic economic question. "Oil is a valuable resource. So why are we using it to make a plastic cup or bottle that might be consumed in five minutes and discarded?" he asks.

The opportunity also has a manufacturing and jobs dimension. Soukas points to inks and dyes, where production is heavily concentrated in China, as one market where seaweed could support domestic alternatives. More broadly, building a seaweed supply chain could create an entirely new industry, the jobs, the businesses and manufacturing that come with it. Seaweed already grows along U.S. coastlines, including Alaska and Maine, while sargassum is abundant across parts of the Caribbean, Mexico and Florida. The question is whether that existing resource can become the foundation for a new domestic industrial ecosystem.

The resource isn't the risk. The economics are.

Processing, he posits, particularly conventional drying, remains one of the industry's biggest challenges. Drying can require substantial energy, potentially eroding some of seaweed's cost and sustainability advantages before the biomass reaches a manufacturer.

According to Soukas, new approaches that process wet seaweed could change that equation, while other research is opening potential uses in building materials and additional industrial products. Soukas explains. "The technology and applications are viable, but cost remains the barrier," Soukas says. "With sufficient scale, that equation could change."

Capital sits at the heart of that equation. Seaweed does not need another sustainability pitch as much as it needs the infrastructure capable of turning abundant biomass into reliable industrial feedstock. Processing technology, production capacity, and commercial demand all need to develop together.

The investment thesis ultimately rests on the question: can an organism growing abundantly in the ocean, wild or farmed, become a serious industrial commodity? If processing costs fall and demand continues expanding across multiple markets, Soukas believes that seaweed could give manufacturers a new source of materials while creating industries around a resource that has largely been underappreciated.
