TNT Eco Materials has developed Fiber Grow™, a patented calcium-carbonate mineralization process that transforms renewable hemp, seaweed, and polymer fibers into high-performance, sustainable materials.
Fiber Grow™ strengthens and enhances the thermal efficiency of concrete while providing lightweight, fire-resistant alternatives for drywall, insulation, and composite panels.
TNT Eco Materials is an additive manufacturing solutions company advancing sustainable innovation in the construction materials sector through its patented Fiber Grow™ technology. Developed in collaboration with NC State University, Ohio State University, and Virginia Tech, Fiber Grow™ mineralizes renewable fibers to create high-performance additives that enhance durability, tensile strength, and insulation capacity while reducing embodied carbon.
The Problem
The global construction industry faces mounting challenges from natural disasters, structural fire damage, rising material costs, declining product quality, and growing environmental pressure. Conventional materials—particularly concrete—are responsible for nearly 8% of global CO₂ emissions. Builders and manufacturers face supply chain instability, unsustainable sourcing, and limited access to scalable, eco-efficient alternatives—impacting housing affordability and the longevity of built environments.
Our Solution
Fiber Grow™ offers a transformative approach by using a patented calcium-carbonate mineralization process that enhances the performance and sustainability of concrete and composite materials. Independent testing at NC State University and Ohio State University verified that at an optimal dosage of 0.135%, Fiber Grow™:
- Reduces cracking
- Increases concrete compressive strength by 1,000 psi (20% improvement)
- Accelerates set time by 40 minutes
- Improves bulk resistivity
- Reduces embodied CO₂ emissions
The material meets ASTM C1157 and NC DOT Class AA standards—proving its readiness for infrastructure and high-performance applications.
TNT Eco Materials’ team combines scientific innovation, engineering execution, and commercialization expertise to deliver sustainable materials at scale.

TNT Eco Materials’ go-to-market strategy focuses on technology licensing, validation partnerships, and strategic acquisitions to achieve global reach without establishing redundant manufacturing operations.
Key Strategies
- Licensing & Integration
License the patented Fiber Grow™ technology to leading producers of concrete, drywall, stucco, and insulation materials for integration into existing production lines. - Validation Partnerships
Collaborate with national and international manufacturers to conduct pilot-scale testing, data collection, and performance validation. - Strategic Acquisition Pathway
Maintain readiness for a buy-out or equity partnership with a major materials supplier seeking exclusive or global rights to Fiber Grow™ technology.
This commercialization-first approach enables TNT Eco Materials to remain lean, agile, and IP-focused while leveraging the infrastructure of established producers to achieve global adoption. Fiber Grow™’s integration across cementitious and non-cementitious applications—including 3D-printed housing—supports the creation of net-zero, energy-efficient homes and infrastructure.
TNT Eco Materials’ revenue model is built around intellectual property monetization through partnerships and licensing rather than in-house manufacturing.
Key Revenue Channels
- Licensing Fees & Royalties
Generated from long-term agreements with domestic and international suppliers integrating Fiber Grow™ into their product lines. - Validation & Data Contracts
Paid collaborations with manufacturers seeking third-party performance data and technical integration support. - Joint Development Agreements (JDAs)
Partnerships that co-develop and brand Fiber Grow™-enhanced products across construction sectors. - Strategic Buy-Out or Acquisition
Partial or complete sale of the Fiber Grow™ intellectual property portfolio to a global materials corporation.
This model supports scaling sustainable innovation through collaboration, accelerating the transition to low-carbon, high-performance materials while ensuring profitability for TNT and its partners. In a housing market defined by escalating costs and environmental strain, Fiber Grow™ provides a bridge between science and construction—creating net-zero, affordable, and durable solutions.
Investment Opportunity
TNT Eco Materials is seeking $1.5 million in seed capital to advance the commercialization and market readiness of its patented Fiber Grow™ additive technology.
The core objective is to secure licensing, validation partnerships, or a strategic acquisition—providing investors with a faster, high-margin return through IP monetization rather than manufacturing scale-up.
Use of Funds
| Allocation | Amount | Purpose |
|---|---|---|
| Validation, Testing & Certification | $500,000 | Complete ASTM/UL and ISO compliance, performance verification, and field trials with NC State, Ohio State, and Virginia Tech to strengthen data integrity and licensing value. |
| Market Development & Licensing | $400,000 | Pursue domestic and international licensing agreements, pilot projects, and acquisition negotiations with major concrete, drywall, stucco, and composite producers. |
| Pilot Optimization & Automation | $300,000 | Enhance pilot-scale production systems at the Zebulon facility to support partner sampling, proof-of-concept batches, and controlled demonstrations. |
| Business Development & Workforce | $200,000 | Add key personnel for business development, QA/QC, and IP management to accelerate partnership execution and deal structuring. |
| Working Capital / IP Protection | $100,000 | Sustain ongoing patent filings, compliance, and pilot operations supporting continued valuation growth. |
This investment will enable TNT Eco Materials to transition Fiber Grow™ from pilot validation to commercial licensing readiness within 12 months, positioning the company for rapid ROI via license agreements or strategic buy-out while expanding sustainable, high-performance building materials globally.
TNT Eco Materials has transitioned from academic research to validated pilot-scale development supported by independent testing and data from NC State University, Ohio State University, and Virginia Tech.
Results confirm Fiber Grow™’s ability to enhance compressive strength by 20%, accelerate curing, and reduce CO₂ intensity while meeting ASTM C1157 and NC DOT Class AA performance standards.
The company operates out of a 25,000 sq. ft. Manufacturing and Research Facility in Zebulon, NC, where additive formulation, mix optimization, and 3D printing trials are conducted. This facility supports industry testing partnerships across cementitious and non-cementitious systems.
Over the next 12 months, TNT Eco Materials will:
- Complete field validation trials and long-term performance studies with academic and industrial partners.
- Finalize product validation agreements with national and global suppliers.
- Advance discussions for licensing and acquisition with material producers seeking high-performance, low-carbon technology integration.
By coupling lab data with real-world application testing, Fiber Grow™ is positioned for commercial deployment across infrastructure, housing, and additive manufacturing markets—serving as a catalyst for sustainable transformation in global construction.
Supported by NC State innovation programs, internal R&D investment, and strategic capital from owner investments and TNT’s development and general contracting division.
The company is currently preparing a $2.5 million seed round to scale pilot manufacturing and commercialization. No prior external equity rounds detailed.
