What Is Tire Recycling? Tire recycling is the process of converting end-of-life or unwanted old tires into material which can be utilized in new items. End-of-life tires typically become candidates for Plastic Recycling Machine when they become no more functional due to 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, in fact it is estimated that four billion unwanted end-of-life tires happens to landfills and stockpiles. Around 246 million scrap tires were generated in the United states in 2015. Consequently, the value of tire recycling can not be understated. Going back a hundred years approximately in to the history of tires, tire recycling was a priority, with the buying price of an ounce of rubber rivaling the price of an ounce of silver. Such economic incentives faded, however.
The introduction of synthetic rubber made from cheap imported oil, as well as through the adoption of steel belted radial tires made tires cheaper (less urgent to recycle) as well as more difficult to recycle. Because of this, worn-out tires increasingly found their way to landfills or were often dumped illegally. Fortunately, tires are now increasing diverted from landfills.
The Urgency of Diversion – Tires brought to landfills or dumped illegally are a significant concern. Old tires provide shelter for rodents, and will trap water, providing a breeding ground for mosquitoes. In landfills, tires consume approximately 75 percent air space, In addition, tires may become buoyant and rise towards the surface should they trap methane gases. This action can rupture landfill liners that are designed to 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 because the Tire Stewardship BC Association and also the work of leading recyclers like Liberty Tire Recycling. In the 246 million tires discarded in 2017, around 88% was consumed in an end-use market.
Markets for Scrap Tires – The 3 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 alternative to using standard 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 and also other industrial applications.
Depending on the kind of Scrap Copper Recycling Machine, tires may be burned whole or even in shredded form. Oftentimes tires should be reduced in proportions to match combustion units, along with other preliminary processing. EPA notes the following good things about burning tires for fuel:
Tires make the equivalent amount of energy as oil and 25% more energy than coal; The ash residues from TDF may contain a lower heavy metals content than some coals; Leads to lower NOx emissions in comparison with many US coals, especially 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 stay in compliance with all the requirements of the permit.
Civil Engineering Applications – Civil engineering applications consumed 17 million old tires in 2015. Such applications can replace other materials like polystyrene insulation blocks, drainage aggregate, or other kinds of fill. The EPA notes that significant material for civil engineering applications originate from stockpiled tires, which are usually dirtier than other sources of scrap tires and can be used embankment fill and then in landfill projects.
Ground Rubber Applications – Ground rubber usage consumed 62 million tires in 2015. Ground rubber can be used to manufacture several Radiator Separating Machine, starting from asphalt rubber, right through to track material, synthetic sports field underlay, animal bedding, and much more. The biggest utilization of ground rubber is perfect for asphalt rubber, utilizing approximately 220 million pounds or 12 million tclzun annually. The biggest users of asphalt rubber are definitely the states of California and Arizona, followed by Florida, with usage expected to grow in other states also.
Samples of other ways to use 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.
