Sargassum on beach

Measurable Impact.
Responsible Infrastructure.

Every ton of sargassum that arrives at our facility represents a measurable environmental outcome — greenhouse gas emissions prevented, contaminants removed, and material diverted from landfill. Impact is not a byproduct of what we do. It is the reason we exist.

EMISSIONS

Estimated 520 kg CO₂e avoided per ton processed.
Estimated 336 kg CO₂e methane avoided per ton.
Methane is 80x more potent than CO₂ over 20 years.

Controlled processing helps reduce unmanaged decomposition and associated emissions.

CONTAMINANTS

Seaweed Greens is an industry leader in arsenic removal from sargassum at scale, with laboratory-supported results demonstrating arsenic removal within five days.

Arsenic and other contaminants are addressed through controlled processing and treatment.

LANDFILL DIVERSION

Diverting sargassum from landfill helps reduce unmanaged decomposition, landfill pressure, and associated environmental risks. Material is directed into a controlled recovery system.
