clean renewable energy

Transform harmful Sargassum blooms into opportunity with Seaweed Greens’ innovative harvest boats and processing systems. Our technology removes toxins such as arsenic and unlocks the full potential of seaweed—converting it into clean biogas that produces up to 200 kilowatts of energy per ton, while also creating safe, nutrient-rich agricultural products. Share your location and the scale of your Sargassum challenge, and together we’ll build a tailored, sustainable solution.

“The Golf Club at The Boca Raton has nearly a century of history, with names like Donald Ross, William Flynn, Sam Snead, and Tommy Armour shaping its legacy. As we approach our centennial and prepare to reopen the course following a full redesign by Brian Silva, maintaining both playability and environmental responsibility remains central to our work.

As an Audubon Certified course, we’re always evaluating how our practices impact the landscape. We began applying Seaweed Greens extract to our greens weekly. While I’ve used other biostimulants in the past, I was drawn to the idea of using a product tied to local environmental challenges in a restorative way.

We manage our greens with low fertility inputs, so our focus is on plant resilience over visual response. Seaweed Greens has become a helpful addition by supporting turf health, especially under stress from drought, disease, or heavy play. It’s one more tool that helps us care for the course with intention and long-term stewardship in mind.”

-- Eric Harchuska, Superintendent, The Boca Raton.
