The Future of Fire Suppression Should Protect More Than Property.

Green Shield Fire was designed with a different goal in mind. While many commercial fire gels focus mainly on holding water, Green Shield Fire uses a bio-composite approach aimed at longer-lasting protection, environmental responsibility, and simplified deployment.

Unlike many conventional gels, Green Shield Fire Hydrogel Bio-Matrix is being developed around a multi-layered thermal defense concept that may include:

• Agricultural biofiber reinforcement
• Structural cellulose matrices
• Ionic cross-linking
• Biomass-derived thermal shielding
• Char-forming protective layers
• Moisture-retention scaffolding
• Thermally reactive bio-composite behavior

Green Shield Fire is being developed as a next-generation fire protection system designed to move beyond conventional water-gel technologies.

Green Shield Fire was selected as a Spring 2026 America's Startup winner , recognizing Trinity's entrepreneurial work developing a new approach to fire protection.

Many polymer-based and silica-enhanced fire gels can come with significant trade-offs.

• Environmental Concerns — Some formulations may contain persistent chemicals that raise environmental and health concerns.
• Difficult Cleanup — Certain gels can require expensive and time-consuming cleanup after deployment.
• Higher Costs — Complex manufacturing processes and specialty ingredients can increase costs.
• Supply Chain Limitations — Many systems depend on synthetic polymers or specialty chemical sourcing.

Green Shield Fire was specifically developed to explore a more sustainable and operationally practical alternative.

Green Shield Fire Bio-Matrix was developed to prioritize sustainability, deployability, and long-term environmental responsibility alongside fire protection performance.

• Easy-to-source renewable materials
• Strong biodegradability and sustainability focus
• Compatibility with standard firefighting equipment
• Minimal cleanup requirements
• Natural breakdown designed with soil and carbon cycling in mind
• Reduced long-term environmental persistence

The system is being developed as a practical field-ready alternative for wildfire response and broader fire protection applications.

Yes.

Green Shield Fire is being developed as a PFAS-free and biodegradable fire suppression alternative designed to avoid persistent synthetic chemicals associated with some legacy firefighting products.

Green Shield Fire is designed for straightforward deployment using existing firefighting infrastructure and equipment.

• Backpack sprayers
• Fire engines
• Helicopter deployment systems
• Drone delivery systems
• Standard high-pressure firefighting equipment

The dry concentrate is intended to mix with water and integrate into existing response workflows with minimal additional training requirements.

Green Shield Fire is being engineered for strong adhesion and reduced slumping on vertical and inclined surfaces.

This addresses a common limitation found in many traditional water-based gels where material runoff can reduce protective coverage during extreme heat exposure.

Comprehensive testing is planned across multiple high-intensity fire scenarios, including:

• Wildland and forest fires
• Lithium-ion battery fires
• Building siding material testing
• Fuel storage and gas container exposure
• Vehicle and engine compartment fires

The goal is to evaluate performance across both wildfire and structural fire protection applications.

Green Shield Fire is being developed with a focus on:

• Biodegradability
• Low aquatic toxicity potential
• Minimal long-term environmental persistence
• Reduced cleanup burden on waterways and soil

The system is intended to align with evolving environmental standards focused on safer firefighting materials and reduced ecological impact.

Final pricing is still being evaluated, but Green Shield Fire is being designed to reduce potential long-term operational costs through:

• Simpler material sourcing
• Reduced cleanup requirements
• Lower environmental remediation burden
• Compatibility with existing firefighting infrastructure

The long-term goal is to provide both environmental and operational cost advantages compared with many synthetic gel systems.

The Green Shield Fire dry concentrate formulation is being engineered for strong shelf stability and simplified storage.

This makes the system practical for:

• Fire departments
• Emergency response staging
• Disaster stockpiles
• Remote wildfire preparedness operations

Many conventional fire gels primarily focus on holding water but can involve higher costs, difficult cleanup, and environmental trade-offs.

Green Shield Fire focuses on combining effective fire protection with real-world operational practicality and environmental responsibility:

• Easier-to-source materials
• Simplified deployment
• Reduced cleanup burden
• Biodegradable design philosophy
• PFAS-free development pathway
• Long-term ecosystem compatibility

The goal is not simply to create another fire gel — but to develop a smarter and more sustainable fire protection platform.

Seaweed is one of the fastest-growing renewable biomaterials on Earth. It grows without freshwater, fertilizer, or agricultural land. Because Mother Nature already solved part of the problem.

More importantly, seaweed-derived polymers can naturally retain moisture. Green Shield Fire is exploring those properties to create a thermal moisture barrier that stays in place longer than plain water. Think of it as nature's fire blanket — only less itchy.

Potentially less expensive than you might expect.

Traditional fire retardants can depend on chemical manufacturing, specialized ingredients, supply chains, storage, and cleanup.

Green Shield Fire is being developed around sustainable, food-grade, and biodegradable materials. Production economics are still being evaluated as development progresses.

Translation: the goal is to spend less on hazardous chemistry and more on protecting firefighters, communities, and forests.

Green Shield Fire is a proprietary blend of sustainably sourced seaweed polymers and biodegradable stabilizers.

Because we are actively protecting our intellectual property, we do not disclose exact concentrations. But we can say this:

• Non-carcinogenic ingredient selection strategy
• Food-grade formulation strategy
• Biodegradable components
• Designed with firefighter safety in mind

Every ingredient is selected with human safety and environmental responsibility in mind.

Many people simply do not know about the environmental and health concerns associated with some modern firefighting materials.

PFAS have been used in a variety of firefighting applications and protective equipment. Even PFAS-free gear can be exposed to other chemical-based fire suppression agents.

Firefighters and agencies care deeply about protecting people, land, air, water, and wildlife. The first step toward safer solutions is awareness.

Firefighter health, PFAS contamination, and environmental exposure concerns are driving industry-wide discussions around safer fire suppression alternatives.

WHY NOW? Learn what the EPA is saying about PFAS.

Seaweed is among the scalable renewable biomaterials being considered for sustainable material development and can be cultivated while also contributing to carbon sequestration.

That's one of the reasons seaweed is so exciting.

Unlike mined chemical ingredients, seaweed cultivation can potentially expand while continuing to capture carbon during growth.

In other words: the raw material grows itself. Nature really overachieved on this one.

That's exactly what the hydrogel is being engineered to do. Unlike plain water, which evaporates rapidly, Green Shield Fire forms a moisture-rich barrier designed to remain in place longer.

In preliminary torch testing, the outer layer chars while helping trap moisture underneath, potentially buying valuable time for firefighters and slowing ignition of vegetation and structures.

Our goal isn't just "wetting things down." Our goal is creating a thermal shield designed to buy firefighters more time.

The industry is rapidly examining alternatives to PFAS-linked chemistry and legacy formulations that may face increasing regulatory scrutiny.

Green Shield Fire is being developed with emerging safety and environmental considerations in mind rather than requiring a future retrofit of legacy chemistry.

Because firefighters already face enough danger without wondering whether the fire suppression products they use could add long-term health or environmental concerns.

Green Shield Fire is being developed with a safety-first mindset, food-based formulation knowledge, and a focus on practical wildfire deployment.

We're not trying to simply "fix" a legacy product. We're building a different alternative.

Great question — because if it turns into mist at 200 feet, nobody wins.

Green Shield's seaweed-polymer system is being engineered to provide greater adhesion than plain water while allowing the viscosity and adhesion characteristics to be tuned.

The formulation is being refined to maintain structural integrity during aerial deployment while still flowing through appropriate pumps and tanker systems.

In technical terms: shear-thinning rheology. In normal-person terms: it should spray smoothly while helping the material stick where firefighters need it.

Green Shield Fire was founded by Trinity through interdisciplinary exploration involving environmental systems thinking, ingredient awareness, wildfire concerns, and regenerative material concepts.
