A tire recycling process designed by Environmental Waste International emits 12,166 metric tons fewer carbon dioxide equivalents compared to incineration, and 3,136 metric tons fewer CO2e compared to the production of crumb rubber, according to results reported by consultancy Pinchin Environmental.
According to the Rubber Manufacturers Association approximately 45 percent of waste tires in the United States are incinerated and approximately 29 percent are converted to crumb rubber, meaning that EWS’ Reverse Polymerization process (pictured) and microwave delivery system is significantly less carbon intensive that the two most commonly used tire recycling techniques, Environmental Waste International says.
In November, the company completed a continuous four-day run of its TR-900 waste tire recycling facility in Sault Ste. Marie, Ontario.
The 100 hour run doubles the previous record announced in June.
The company said that the four-day run is a milestone toward continuous 24/7 operation of its waste tire recycling facility. Sale and construction of a commercial facility is the next step, CEO Dr. Daniel Kaute said.
Earlier in 2013, NASCAR named Liberty Tire Recycling as the official tire recycler of NASCAR Green, a month-long, industry wide effort to reduce the sport’s carbon footprint. The program should recycle around 120,000 Goodyear tires across NASCAR’s top three national series each year.
In 2012, Hertz and Liberty Tire Recycling launched what they called the first nationwide tire recycling program in the US car rental industry.
Hertz says the program also makes it the first to commit to zero landfill waste for tires.
