Materials from a Recovered Feedstock.
DURTEQ™ is building a diversified product portfolio from recovered sargassum and complementary circular feedstocks. Our platform is designed to separate, refine, formulate, and manufacture materials for markets that need more resilient supply chains and more productive uses for recovered resources.

Explore Modular Pool ShellsThe Material Platform
One circular matrix, pressed and molded into the products above
DURTEQ’s building products come from one bio-composite matrix: invasive pelagic sargassum, MYCOSARG™ mycelium, recycled HDPE and PET, and geopolymer chemistry, including fly ash and slag. Sheets are hot-pressed. Profiles, shells, and furniture are molded. The matrix is specified without added formaldehyde, and interior faces are developed for low-VOC rooms.
These figures are the platform characteristics DURTEQ publishes for that matrix. They are not a building-code approval for every molded part. A wall, a tank, a pallet, or a house still takes the specification and the testing its jurisdiction requires. A limited lifetime warranty is offered with a supply agreement.
| Characteristic | Published figure |
|---|---|
| Standard sheet | 4 ft × 8 ft |
| Custom sheet | Up to 10 ft |
| Density | 700–850 kg/m³ |
| Water absorption | < 0.5% |
| Flexural strength | > 8.5 MPa |
| Screw pull-out | ≥ 150 N |
| Process | Hot press and injection mold, 130–175°C, 1–6 MPa |
| Fire | Specified to Class A, ASTM E84, with borate minerals in the matrix |
Lines on this platform
- Interior wall and partition boards
- Exterior facades for coastal weather, UV, and driving rain
- DURTEQ™ ThermoShield, the waterproof thermal-insulation line
- DURTEQ™ QuietCore / ArtSound™, the acoustic line, specified toward an NRC of 0.85
Finishes
Stone, wood, and architectural color collections. Faces are raw matte, paint-ready, laminated stone, woodgrain, acoustic relief, or a custom molded form.
Where the matrix is aimed
Marine edges, coastal construction, high humidity, hurricane zones, commercial buildings, and agricultural operations.
One Integrated Resource-Recovery Platform
The value of the DURTEQ™ platform is not limited to one finished product. Recovered biomass can be directed into different commercial pathways according to composition, market requirements, processing economics, and verified product suitability.
From building materials to specialty ingredients, energy products to climate infrastructure, every product line leverages the same biological engine and traceability infrastructure. This diversification creates resilience and flexibility across markets and geographies.
Platform Architecture
- Feedstock separation and preprocessing
- Biological metal capture and refinement
- Multiple formulation pathways
- AXERP registry and traceability
- Scalable manufacturing
