From Sargassum Crisis to Circular Industry

SargaBio’s biorefinery project transforms invasive sargassum into high-value biomaterials such as alginate, cellulose,biofertilizer, and inputs for sustainable packaging.

We are building the infrastructure needed to convert a costly coastal problem into a scalable materials platform forthe Caribbean and beyond.

El problema y la solución

Two environmental challenges. One industrial solution.

Every year, massive sargassum blooms impact coastlines, ecosystems, tourism, and local economies across theCaribbean. At the same time, industries still depend heavily on fossil-based materials with high environmentalfootprints.

SargaBio’s biorefinery project addresses both challenges at once: we recover value from problematic biomass andconvert it into industrial inputs that can replace more polluting materials.

Summary

What is the SargaBio biorefinery?

The SargaBio biorefinery is a vertically integrated processing project designed to use sargassum as feedstock for theproduction of multiple high-value outputs.

Instead of treating sargassum as waste, we process it as a strategic raw material. Through extraction andfractionation, the biorefinery is designed to produce:

Products and solutions

01
01

It unlocks local value from an urgent environmental problem

Sargassum imposes major environmental and economic costs on coastal communities. A biorefinery creates a
productive use for this biomass instead of leaving it to decompose onshore.

02
02

It reduces dependence on imported raw materials

By extracting key compounds locally, SargaBio can strengthen its supply chain and reduce exposure to international
raw material volatility.

03
03

It supports scalable sustainable manufacturing

Vertical integration enables SargaBio to improve cost structure, material consistency, and long-term competitiveness
in biomaterials.

04
04

It creates regional environmental and social impact

The project can generate jobs, support traceable collection systems, and create economic opportunities in coastal
regions affected by sargassum.

The process

How the system works

01

Collection and supply

We work to secure traceable sargassum supply from affected coastal regions.

02

Pre-processing and stabilization

Collected biomass is sorted, treated, and prepared for industrial transformation.

03

Extraction and fractionation

The biorefinery separates valuable compounds such as fucoidans, alginate, cellulose, and other usable fractions.

04

Manufacturing integration

These outputs can feed BioPlaster’s materials platform, including films, bags, and future biomaterial applications.

05

Circular valorization of residual streams

Residual biomass is directed toward additional products such as biofertilizer, maximizing resource efficiency.
