What Is Tire Recycling? Tire recycling is the process of converting end-of-life or unwanted old tires into material that may be utilized in new products. End-of-life tires typically become candidates for Tire Recycling when they become no longer functional as a result of wear or damage, and can no longer be re-treaded or re-grooved.
You can find over one billion end-of-life tires generated annually, worldwide, and it is estimated that four billion unwanted end-of-life tires happens to landfills and stockpiles. Around 246 million scrap tires were generated inside the United states in 2015. As a result, the significance of tire recycling cannot be understated. Returning a hundred years or so to the background of tires, tire recycling was actually a priority, with the cost of an ounce of rubber rivaling the price of an ounce of silver. Such economic incentives faded, however.
The introduction of synthetic rubber produced from cheap imported oil, along with from the adoption of steel belted radial tires made tires cheaper (less urgent to recycle) along with more challenging to recycle. Because of this, worn out tires increasingly found their way to landfills or were often dumped illegally. Fortunately, tires are increasing diverted from landfills.
The Urgency of Diversion – Tires sent to landfills or dumped illegally certainly are a significant concern. Old tires provide shelter for rodents, and can trap water, providing a breeding ground for mosquitoes. In landfills, tires consume up to 75 percent air space, Additionally, tires could become buoyant and rise towards the surface when they trap methane gases. This step can rupture landfill liners that can prevent contaminants from polluting surface and ground water. Approximately 700 to 800 million old tires were estimated to become illegally stockpiled in 1994, with that total reduced to approximately 275 million by 2004.
Recycling has been assisted through such programs as the Tire Stewardship BC Association and the work of leading recyclers such as Liberty Tire Recycling. Of the 246 million tires discarded in 2017, around 88% was consumed within an end-use market.
Markets for Scrap Tires – The three largest markets for scrap tires include tire-derived fuel (TDF), civil engineering applications, and ground rubber applications/rubberized asphalt.
Tire Derived Fuel – About 117 million end-of-life tires were utilized as TDF in 2015. EPA acknowledges tire-derived fuels as being a viable substitute for the use of fossil fuels, so long as proper regulatory controls have been in place. Scrap tires are prized for their high heating value, and they are used effectively in Portland cement kilns along with other industrial applications.
Depending on the kind of Car Tires Shredder, tires can be burned whole or in shredded form. Oftentimes tires should be reduced in proportions to fit combustion units, as well as other preliminary processing. EPA notes these benefits to burning tires for fuel:
Tires produce the equivalent amount of energy as oil and 25% more energy than coal; The ash residues from TDF might have a lesser heavy metals content than some coals; Brings about lower NOx emissions when compared to many US coals, in particular the high-sulfur coals. EPA stresses that facilities utilizing TDF should have a tire storage and handling plan, necessary permits for applicable state and federal environmental programs; and stay in compliance with the requirements of the permit.
Civil Engineering Applications – Civil engineering applications consumed 17 million old tires in 2015. Such applications can replace many other materials such as polystyrene insulation blocks, drainage aggregate, or other kinds of fill. The EPA notes that significant material for civil engineering applications result from stockpiled tires, which can be usually dirtier than other sources of scrap tires and can be used as embankment fill as well as in landfill projects.
Ground Rubber Applications – Ground rubber usage consumed 62 million tires in 2015. Ground rubber can be used to manufacture numerous Plastic Crushing Mill, starting from asphalt rubber, to track material, synthetic sports field underlay, animal bedding, and much more. The largest usage of ground rubber is made for asphalt rubber, utilizing approximately 220 million pounds or 12 million tclzun annually. The largest users of asphalt rubber are definitely the states of California and Arizona, then Florida, with usage anticipated to grow in other states also.
Examples of other uses for ground rubber include:
Groundcover under playgrounds, Playground tiles, Anti-fatigue mats, Animal bedding, Running tracks, Equestrian footing, Underlay and infill for athletic fields. Another 20 million tires were consumed for other purposes.
