01 · PAVEMENT

Rubberized Asphalt

Scrap tire rubber is processed and blended into asphalt pavement, extending road life and cutting the volume of tires headed to landfill.

02 · MATERIALS

Rubber from Dandelions

A domestic, hydroponically-grown alternative to imported natural rubber — a national security and supply chain hedge.

03 · LOGISTICS

Rubberized Pallets

Composite pallets made from recycled tires and plastics — more durable than wood, more repairable than plastic.

04 · RAIL

Rubberized Railroad Ties

A 100%-recycled composite tie engineered for a 50-year service life — roughly 3x a traditional wooden tie.

01 · Pavement

Rubberized Asphalt Pavement

There are millions of scrap tires discarded each year worldwide, posing environmental health hazards and pollution. Repurposing that rubber into asphalt-rubber pavement gives it a second life as durable road infrastructure.

Rubber from Dandelions

The United States faces a national security risk from its dependence on foreign-grown natural rubber — over 90% of it comes from Southeast Asia. Natural rubber feeds more than 50,000 products beyond tires, including medical supplies and military vehicles and aircraft, so a supply disruption carries real defense and economic consequences.

THE MARKET

A $22.4B market the U.S. sits out of entirely

2017 global natural rubber production: $22.4 billion world, $0 United States

Global natural rubber production was worth $22.4 billion in 2017 — the United States' share of that production was $0.

THE SOURCE

92% of natural rubber comes from Asia

Natural rubber source map: Asia 92%, Africa 5%, the Americas 3%

The Americas supply just 3% of natural rubber and Africa 5%, leaving the U.S. with effectively zero domestic competition and a real opening for a made-in-America source.

The Problem

Five risks of import-dependent rubber

01

Reliance on Foreign Imports

Nearly all U.S. natural rubber is imported, with no meaningful domestic production to fall back on.

02

Supplier Concentration Risk

A lack of variety in supplier location creates environmental and political exposure.

03

Environmental Vulnerability

Rubber tree crops are susceptible to blight, plague, drought and other environmental shocks.

04

Labor- & Time-Intensive Harvesting

Traditional latex tapping is slow and labor-intensive, limiting scalability.

05

Unsafe Work Environments

Harvesting conditions in traditional rubber-growing regions are often unsafe and inconsistent.

THE SOLUTION

Produce rubber domestically, at commercial scale

Grow natural rubber in the U.S. at a commercial, sustainable level using a genetically-improved rubber dandelion — Taraxacum kok-saghyz (TKS) — cultivated hydroponically indoors.

The Value Chain

More than rubber: a full biorefinery output

Rubber dandelion cultivation and harvesting feeds a biorefinery process that yields far more than latex — rubber, animal feed, bioplastic, biogas and bioethanol all come from the same crop.

Impact

Environmental and social returns

ENVIRONMENTAL

Sustainable Production

Indoor hydroponic cultivation replaces deforestation-driven rubber tree farming with a controlled, sustainable growing process.

ENVIRONMENTAL

Renewable Resource

Rubber dandelion is a fast-cycling renewable crop rather than a decades-old tree plantation.

SOCIAL

U.S. Job Creation

A domestic rubber dandelion industry creates cultivation, processing and biorefinery jobs on U.S. soil.

SOCIAL

Reduce Foreign Dependencies

Domestic production directly reduces U.S. reliance on Southeast Asian rubber imports.

SOCIAL

Safer Working Conditions

Controlled-environment indoor cultivation replaces the unsafe, inconsistent conditions of traditional latex tapping.

Research Validation

Independently researched, not just theoretical

Ohio State University's Katrina Cornish — an endowed chair and director of the university's alternative natural rubber research program — has published on rubber dandelion's high-yield potential in controlled-environment vertical hydroponic systems, in Rubber & Plastics News.

03 · Logistics

ESG Rubberized Pallets

About 850 million pallets are manufactured in the U.S. each year, built primarily from wood, plastic, or rubber. Both incumbent materials have real drawbacks that GTG's composite rubberized pallets are designed to solve.

Download: Composite Pallets Overview (PDF)
WOOD

Splinters, warps, wears out

Wooden pallets splinter and warp under repeated load, and lack the longevity and durability to hold up through a full life-cycle of reuse.

PLASTIC

Durable, but hard to recycle

Plastic pallets last longer but are produced through energy-intensive, high-emission processes. Damaged plastic pallets can't be repaired — only replaced with new ones — and recycling them is itself energy-intensive, while disposal adds to non-recyclable solid waste.

THE IMPACT

Wooden pallets consume ~7.6B board feet of lumber a year

Discarded wooden pallets in a landfill pile

That's enough lumber to cover an area 10 times the size of New York City — a $6 billion annual industry where roughly half of all pallets are used once and discarded. Galvanized nails make them hard to salvage, so most end up in landfills.

THE PROBLEM

330M scrap tires and 73M tons of plastic waste, every year

GTG's engineers converted that waste stream into a solution: used tire crumb rubber blended with waste plastic and a proprietary chemical produces a composite thermoplastic elastomer (TPE) — a moldable input material for products like logistics pallets.

THE PROCESS

TPE Molding Process to Pallets

THE PLAN

Executive Summary

Executive summary slide: objective is implementation of recycling tires and plastics in the USA to produce pallets, backed by a team with over 120 combined years of recycling industry experience

A team with 120+ combined years of experience in recycling plant design, R&D, and equipment operation is behind the technology transfer, manufacturing setup, and testing lab needed to bring it to market.

BEYOND PALLETS

The Possibilities: A Closed-Loop, Zero-Waste Economy

The same recycling process feeds a much wider set of applications beyond pallets — from roadways and sound barriers to sports surfaces, playgrounds, and gym flooring — all in service of a closed-loop, zero-waste economy.

04 · Rail

ESG Rubberized Railroad Ties

Extreme weather is the Achilles' heel of the U.S. rail network. Of the roughly 700 million wooden railroad ties installed nationwide, 20 million must be replaced every year — an annual expenditure exceeding $1.5 billion. GTG's composite ties, made from 100% recycled waste plastics and tires, are built to change that math.

01

Weather Immunity

Doesn't absorb moisture, rot, or degrade underwater flooding, and resists the thermal stress that causes sun kinks in summer heat.

02

Toxicity-Free

Wooden ties are treated with creosote and chromated copper arsenate to resist rot and insects — chemicals that can leach into soil and water. Composite ties carry no such treatment.

03

Non-Combustible

Low electrical conductivity and non-combustible construction, with better lateral stability than wood for high heat and heavy loads.

THE IMPACT, PER 1,000 KM OF TRACK

Superior Physical Performance and Extreme Durability

Impact of 1000 km of track using 2,000,000 composite railroad ties: about 240,000 metric tons of greenhouse gas emissions avoided, 5,000,000 trees saved, 150,000,000 kg of recycled plastic used, and over 6 million scrap tires diverted from landfill

Every 1,000 km of track laid with GTG's composite ties represents roughly 2,000,000 ties, ~240,000 metric tons of avoided greenhouse gas emissions, ~5,000,000 trees saved, 150,000,000 kg of recycled plastic (including ocean plastics) repurposed, and more than 6 million scrap tires diverted from landfill.

OUR SOLUTION

Future-Proof Infrastructure

Composite ties staged and ready for shipment — produced at volume from recycled plastics and scrap tire rubber to supply rail infrastructure projects at scale.

Why It Matters

Tire waste is an environmental problem with a material solution

Scrap tires that end up in landfills or illegal dump sites pose fire risk, leach chemicals, and provide breeding grounds for pests. Repurposing that rubber into pavement, pallets, railroad ties, and other durable goods converts a liability into infrastructure.
