A DIVISION OF TGI GROUP · CRITICAL RESOURCE RECOVERY
Trash to Cash.
Liability to Sovereign Asset.
DURTEQ converts the Caribbean’s Sargassum crisis into a verified industrial supply chain — harvesting invasive seaweed offshore, detoxifying it through cold-chemistry biorefining, and issuing blue carbon credits on the AXERP registry.
Six Stages, Ocean to Ledger
Maritime Shield
AI-Guardian™ sensor fusion and autonomous drone patrols detect and intercept Sargassum mats offshore — before landfall, before beach decomposition releases hydrogen sulphide and methane.
Harvest & Dewater
V-Hull Harvester Barges collect at sea with certified zero bycatch and dewater on board, cutting transported mass by 40% before the biomass ever reaches shore.
DRYBOX™ & PAMPER
Solar thermal drying paired with PAMPER filtration strips heavy metals from the feedstock — arsenic falls from 62–89 mg/kg to 0.8–2.6 mg/kg, clearing the threshold for commercial materials.
Mycorefinery Protocol
Cold-chemistry fermentation with Aspergillus oryzae replaces energy-intensive thermal cracking, unlocking alginates, fucoidan, and structural fibre without high-temperature processing.
Energy Self-Sufficiency
Onboard pyrolysis converts residual biomass into process heat and power, so the harvesting and refining chain runs without drawing on host-nation grid capacity.
Valorize & Verify
Every tonne harvested, processed, and sequestered is recorded on the AXERP carbon registry — auditable provenance from GPS harvest coordinates through to issued credit.
Registry Infrastructure →Six Revenue Lines From One Feedstock
A single harvest yields construction materials, nutraceuticals, fuel, agricultural inputs, composites, and tradeable carbon.
Low-carbon cementitious blends that substitute processed biomass ash for Portland clinker in structural and non-structural applications.
High-value alginates and fucoidan extracts for the nutraceutical, cosmetic, and pharmaceutical supply chains.
Densified briquettes for industrial thermal load, displacing imported coal and fuel oil in island economies.
Detoxified soil amendments and foliar bio-stimulants for regional agriculture, closing the nutrient loop on land.
Fibre-reinforced composites and 3D-printing filament for modular construction and infrastructure components.
Sequestration credits issued as ERC-3643 permissioned security tokens — compliance-native, transferable, and auditable on-chain.
Carbon Infrastructure
as a Service.
DURTEQ does not sell equipment and leave. Host nations receive the full stack — harvesting fleet, refining capacity, and the AXERP registry that makes their carbon inventory legible to international buyers — aligned to Article 6.4 of the Paris Agreement.
The sovereign retains ownership of its carbon asset. DURTEQ operates the infrastructure that proves it exists.
