What Is Tire Recycling? Tire recycling is the method of converting end-of-life or unwanted old tires into material that can be utilized in new products. End-of-life tires typically become candidates for Scrap Tire Recycling once they become no longer functional as a result of wear or damage, and can no longer be re-treaded or re-grooved.
There are over one billion end-of-life tires generated annually, worldwide, and it is estimated that four billion unwanted end-of-life tires exist in landfills and stockpiles. Around 246 million scrap tires were generated within the U.S. in 2015. Because of this, the significance of tire recycling can not be understated. Going back a hundred years approximately into the background of tires, tire recycling was actually a priority, with the buying price of an ounce of rubber rivaling the buying price of an ounce of silver. Such economic incentives faded, however.
The development of synthetic rubber produced from cheap imported oil, as well as from the adoption of steel belted radial tires made tires cheaper (less urgent to recycle) as well as harder to recycle. As a result, 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 delivered to landfills or dumped illegally really are a significant concern. Old tires provide shelter for rodents, and may trap water, providing a breeding ground for mosquitoes. In landfills, tires consume as much as 75 percent air space, In addition, tires could become buoyant and rise for the surface if they trap methane gases. This action can rupture landfill liners that can prevent contaminants from polluting surface and ground water. Approximately 700 to 800 million old tires were estimated to be illegally stockpiled in 1994, using that total reduced to approximately 275 million by 2004.
Recycling has become assisted through such programs because the Tire Stewardship BC Association as well as the work of leading recyclers like Liberty Tire Recycling. In the 246 million tires discarded in 2017, around 88% was consumed inside 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 option to the usage of non-renewable fuels, provided that proper regulatory controls are in place. Scrap tires are prized for his or her high heating value, and they are used effectively in Portland cement kilns as well as other industrial applications.
Depending on the type of Scrap Tire Recycling Equipment, tires can be burned whole or in shredded form. Oftentimes tires should be reduced in dimensions to suit combustion units, in addition to other preliminary processing. EPA notes these advantages to burning tires for fuel:
Tires make the equivalent amount of energy as oil and 25% more energy than coal; The ash residues from TDF might have a reduced chemical toxins content than some coals; Leads to 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 federal and state environmental programs; and be in compliance with all the requirements of this permit.
Civil Engineering Applications – Civil engineering applications consumed 17 million old tires in 2015. Such applications can replace many other materials including polystyrene insulation blocks, drainage aggregate, or other kinds of fill. The EPA notes that significant material for civil engineering applications come from stockpiled tires, that are usually dirtier than other causes of scrap tires and bring 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 produce several Plastic Film Crusher, starting from asphalt rubber, right through to track material, synthetic sports field underlay, animal bedding, and a lot more. The biggest usage of ground rubber is perfect for asphalt rubber, utilizing approximately 220 million pounds or 12 million tclzun annually. The greatest users of asphalt rubber are the states of California and Arizona, followed by Florida, with usage expected 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.
