Trash to Cash.
Liability to Sovereign Asset.
The Caribbean's record Sargassum crisis is now the world's largest untapped marine feedstock. DURTEQ intercepts it offshore, detoxifies it, and transforms it into high-value materials and verified carbon credits. One biological engine, two feedstocks — the same protocol recovers critical minerals and rare earths from the world's industrial waste.
A Biological Emergency
The Caribbean's coastlines, health, and economies are under siege
Unprecedented Volume
A record 37.5 million metric tons in 2025 — projected up to 40 million in 2026. The two species can double their biomass in just 11 days.
Economic Destabilization
Tourism is 16% of GDP and ~900,000 jobs in the Dominican Republic alone. Inundations cut affected-area tourism revenue 35–50%.
Public Health Crisis
Decomposition releases toxic hydrogen sulfide (H₂S). Over 11,400 acute exposure cases were reported in the French West Indies in a single year.
Escalating Costs
Cleanup runs ~$1.1M per kilometer of coastline annually in the hardest-hit regions — a recurring, non-discretionary public expense.
The DURTEQ Solution
We move mitigation from the shoreline to the open ocean — and capture the value
Maritime Shield
An autonomous hub-and-spoke fleet of satellite drones and interceptor catamarans, guided by our patent-pending AI-Guardian™ sensor fusion (RGB + Near-Infrared + Thermal), corrals Sargassum in open water under a certified Zero-Bycatch protocol — before it rots on the beach.
Harvest & Dewater
V-Hull Harvester Barges with a split-bow funnel and mesh-belt conveyors collect biomass without sand contamination. An onboard Water Squeeze instantly cuts raw mass up to 40%, so we transport valuable organic matter — not seawater.
DRYBOX™ Pre-Processing
Solar + photovoltaic thermal drying brings moisture to target, while the PAMPER filtration system washes out corrosive salt and soluble impurities — with responsible brine effluent management.
Mycorefinery Protocol
Our breakthrough: a low-temperature "Cold Chemistry" fermentation using Aspergillus oryzae. Fungal cell walls act as molecular magnets, locking arsenic and heavy metals into an inert matrix — solving the industry's Arsenic Barrier while preserving valuable polymers.
Energy Self-Sufficiency
Onboard pyrolysis converts a portion of dried biomass into syngas and bio-oil that power the fleet, drones, and dryers — a closed-loop system that is energy-independent and carbon-neutral.
Valorize & Verify
Clean feedstock becomes building materials, bio-stimulants, and marine extracts — while every ton of sequestration and avoided emissions is measured, reported, and verified on the AXERP registry.
One Biological Engine, Two Feedstocks
The same chemistry that detoxifies Sargassum recovers metals from industrial waste
Breaking the arsenic barrier was the hardest technical gate in the Sargassum business — and clearing it proved something larger. Stripping arsenic out of biomass is selective biological metal capture, and the same fungal and cold-chemistry mechanisms pull gold, silver, gallium and rare earths out of industrial waste.
The feedstock changes; the engine does not. That second feedstock — fly ash, red mud, tailings and e-waste — is a business in its own right.

Sovereign Carbon Infrastructure
Under Article 6.4 of the Paris Agreement, nations must operate national registries to verify and trade carbon credits. Through the AXERP platform, DURTEQ delivers Sovereign Carbon Infrastructure-as-a-Service.
- AI-driven MRV. Real-time Measurement, Reporting & Verification via satellite data — an institutional-grade defense against greenwashing.
- ERC-3643 tokenization. Compliant Blue Carbon security tokens nations actually own and control.
- National exclusivity. Once adopted as the national Article 6.4 registry, AXERP becomes the sovereign standard — a durable data moat.
"Sovereign-as-a-Service": recurring government tipping fees layered beneath scalable commercial revenue — with a defensible data moat.
AI measurement
Satellite, drone, and field data are turned into a carbon inventory. The workflows cover REDD+, IFM, ARR, and blue carbon, and they keep the model run with the credit.
One lifecycle
Registration, validation, issuance, transfer, and retirement. Serial numbers are there so the same ton cannot be issued twice.
Article 6 records
Authorization flags, reporting exports, and separate roles for the national authority, the project, and the verifier.
Sovereign hosting
The registry can run in a national data center or a sovereign cloud. The government keeps administrative ownership.
24-Month Execution Roadmap
