To remove 500,000 tonnes of CO₂ by 2030 by intercepting toxic sargassum seaweed and upcycling it with local biomass into biochar and compost that safeguard ecosystems, rejuvenate soils, and are used by their farm partners to grow abundant, chemical-free harvests—creating a regenerative loop from ocean to land to table.

The Sargassum Problem

Sargassum blooms crash onto tropical shores, where they decay and release methane, a greenhouse gas 80x more potent than CO₂. They also emit toxic hydrogen sulfide fumes, suffocate marine wildlife, contaminate freshwater supplies, and at peak bloom, cause 40% revenue loss for local coastal businesses.

These blooms have surged 600% over the past 10 years, reaching 37M tonnes in 2025 alone.

A Category-Defining Solution

Grogenics came up with a first-of-its-kind circular model that:

• Slashes methane emissions.
• Generates nutrient-rich compost via biochar and their unique bioremediation for community partners.
• Revives local reefs for artisanal fishers, tourism, wildlife, and biodiversity.

This model is already operational in the Caribbean and Mexico and has been engineered to scale.

How Grogenics’ Circular Model Works

Working with resorts, Grogenics intercepts sargassum before it even has a chance to decay, bringing it to their upcycling facility where it is composted, detoxified, and enriched with biochar to create a regenerative soil amendment that is 100% safe.

They then deliver it to 150+ women-led farms, helping them adopt sustainable practices like ditching chemicals and cutting water use — closing the loop.
