TIRE RECLAMATION RECYCLING INNOVATION
Green Recycling Solutions International (GRSI) has pioneered a patented cryogenic technology for tire recycling and is excited to collaborate with Dr. Darvish to develop a scalable prototype focused on environmental sustainability and job creation. Our existing prototype processes tire fragments at -120°C using liquid nitrogen and incorporates a jaw crusher and fracturing mill. However, during processing, the tire pieces can heat up, affecting the quality of recycled outputs such as crumb rubber, steel wire, and tire cord.
To address this, our project proposes integrating a temperature-controlled cryogenic compartment to maintain consistently low temperatures throughout the shattering process. This enhancement will ensure optimal temperature control, resulting in improved quality of the recycled materials. Our goal is to deliver a fully functional prototype with the potential to expand for large-scale operations. The successful implementation of this advanced technology offers significant opportunities for environmental impact and job creation in the tire recycling industry.
TIRE RECYCLING
Over 240 Million Tires are disposed of, in the United States, on an annual basis. Many tires end up in landfills, and become breeding grounds for mosquitoes, which then spread disease.
​
The rest of the tires are recycled, by the chopping and grinding method, using environmentally hazardous and expensive liquid nitrogen to freeze the tires before processing them through the machines.
PATENTED TECHNOLOGY
Green Recycling Solutions International (GRSI) owns the worldwide rights to a patented technology that uses compressed air to freeze tires, and a unique technology that also extracts the steel tread and fiber found inside the tires. This method is 100% environmentally safe and much less expensive than using liquid nitrogen.
​
This method also produces a fine grade of crumb rubber (a traded commodity). The steel tread can also be recycled and re-sold.
Green Recycling Solutions International, Inc (GRSI) has a patented semi-cryogenic technology that uses the contraction and expansion of ambient air to freeze tires. The air is passed through a series of compressors, and this process reduces the air temperature to -175 degrees (minus) or greater, to freeze the tire, and renders it to a brittle state. Once brittle, the tire passes through our proprietary fracturing mill.
The fracturing mill shatters the tires into rough pieces of rubber, and fed through mesh screens that determine the grade and size of the end-product, which is crumb rubber. The steel wire and tire cord are completely separated from the tire and are directed into their own recycling bin. When fully operational, this technology will be able to recycle 2 million tires annually, thereby reducing the CO2 footprint by 161,500,000 lbs., which is equivalent to 2,907,000,000 gallons of gasoline. The average 20 lb. tire has 2.5 lbs. of Steel Wire, and a Single Tire Cord is 22,1185.003 cubic inches.
Thus, when we're recycling the optimum number of tires, annually (2 million) the technology will produce: 2.5 million lbs. of steel wire, 36 million lbs. of crumb rubber, and I million lbs. of tire cord that can be further recycled into other products. The design has the advantage of recycling tires without producing any petroleum dust and/or smoke that is normally produced by systems that are based on chopping and grinding. With this design the main components of a tire: crumb rubber, steel wires and nylon cords will be separated and recycled to be used in other industries.
Crumb rubber is currently used as 20% of the asphalt mix in some states, in addition to the other end-product uses for crumb rubber, such as household items, car parts, injection molding technology, etc. The nylon cord can be used as a additive to make stucco, fiberglass and carpeting. Steel wire can be reused to make a host of products for construction or household products.

Tech Transfer Partnership with Temple University
​
The Tech Transfer Partnership is spearheaded by Vincent Gori, a leader in tire recycling consulting and manufacturing, and Professor Kurosh Darvish, Dept. Chair of Temple University College of Engineering. The primary aim is to advance GRSI’s technology by scaling up to a functional prototype that will contribute to sustainable manufacturing and create new job opportunities in the region. Temple University’s involvement, under the supervision of Professor Darvish and Mr. Gori, President of GRSI, ensures that both graduate and undergraduate students are actively participating in the design and implementation of the prototype. This hands-on experience provides students with a rare opportunity to apply academic concepts to practical, real-world challenges while learning from industry experts like Mr. Gori. The collaboration between GRSI and Temple University equips GRSI with innovative technologies and academic experience that would be difficult to acquire independently. This partnership not only strengthens GRSI’s competitive advantage but also enhances the university’s research profile. The successful completion and scale-up of this project will have significant impact on Pennsylvania, driving job creation and positioning the state as a leader in advanced tire recycling solutions.
The enhancement of the current tire recycling prototype, developed through the partnership between GRSI and the Department of Mechanical Engineering at Temple University, significantly improves the process efficiency and quality of byproducts. By integrating a cryogenic chamber into the existing system, which includes a jaw crusher and a fracturing mill, the temperature of tire pieces are consistently maintained at or below -120°C, ensuring they remain below the glass transition temperature of rubber. This modification prevents unwanted temperature rise during processing, thereby preserving the integrity and quality of the resulting crumb rubber, steel wire, and tire cord.
Maintaining the low temperature results in a cleaner, more uniform product with enhanced value and market potential. Following the successful incorporation of the cryogenic chamber, the prototype will be primed for scale-up, opening pathways for broader industrial application. This advancement will not only enhance the recycling process but also align with environmental goals and support job creation, demonstrating the potential for positive economic and ecological impacts.
The rapid increase in End-of-Life Tires (ELTs) has created significant environmental challenges, making their recycling a crucial approach for mitigating ecological impact. The recycling process for ELTs starts with complex mechanical procedures that break down rubber into smaller particles of varying sizes. These processes not only yield valuable products for a wide range of applications but also set the stage for advanced chemical and thermal recycling methods. Cryogenic grinding, an effective method for processing ELTs, involves cooling waste rubber below its glass transition temperature. At this low temperature, the rubber becomes frozen and brittle, enabling it to be efficiently crushed using equipment such as a jaw crusher or fracturing mill. This technique not only simplifies the mechanical breakdown of rubber but also enhances the quality of the resulting materials for further use.
For initial testing, liquid nitrogen served as the cryogenic medium. However, for the scaled-up version, it is more cost-effective to use the contraction and expansion of ambient air to freeze the tires. This process involves passing air through a series of compressors and expansion valves, which lower it temperature to -120C degrees, rendering the tire rubber to a brittle state.
Technology
Currently the method that is most commonly used to recycle tires is to “chop and grind”, which pollutes the air with petroleum dust. The process only chops up the rubber without extracting the tire cord or steel wire.
Tires are also being burned in kiln ovens, The ovens emit known carcinogens into the air, and the kilns often burn through the floor, thus releasing toxins into the soil, air, and water ways. grade crumb rubber. This method is expensive, and emits pollutants into the air, soil and waterways through leaching.
Our method is efficient, less expensive, and provides the opportunity to produce a superior grade crumb rubber, & cord & wire which produces additional income opportunities.
The economic viability of our technology is not dependent on disposal fees. Our system has a throughput rate of 2.3 tires/minute, with very competitive energy consumption costs relative to other systems in the marketplace. The high throughput yield of the GRSI system, when combined with the lower unit production operating cost for the system provides strong competitive advantages for operators using the GRSI system.
Our technology purchasers have the product and market support from Green Recycling International Inc. High gross margins and low operating costs will enable the operator to ride out the inevitable shifts in the price of crumb in the market.
Other ambient technologies tend to produce a coarser grade of crumb rubber, lower rubber yields as well as a higher level of product contamination. This equates to lower revenues generated per processed tire.
-
Ambient technologies require extensive equipment to shred, cut and granulate tires which involves very significant maintenance costs and down-time ( ie: frequent knife and blade sharpening and replacement, for instance.
-
Ambient systems generate high energy costs.
Other Cryogenic Technologies vs. GRSI:
-
Cryogenic operators need to freeze tires with very expensive liquid nitrogen.
-
GRSI has proven that to produce crumb rubber cryogenically, the tires simply need to be frozen below its “glass point, i.e. the temperature at which rubber can be shattered like glass. Any additional cooling translates into costly wasted cooling energy
-
The most important difference between the GRSI cold air based system and liquid nitrogen is the very cost of the liquid nitrogen, which is 2-3 times more expensive than cold air. In addition, liquid nitrogen is not readily available everywhere in the world,(contrary to air!
-
The last critical advantage that GRSI has over its competitors is its unique and patented “Fracturing Mill” which separates all of the tire components and reduces the tire rubber to the size of crumb rubber.
