Burning tires is lower on the hierarchy of reducing waste than recycling, but it is better than placing the tire waste in a landfill or dump, where there is a possibility for uncontrolled tire fires or the harboring of disease vectors such as mosquitoes. [3] Tire Derived Fuel is an interim solution to the scrap tire waste problem.
Rolling resistance is the main key factor in measuring the energy efficiency of a tyre and has direct influence on the fuel consumption of a vehicle. A set of tyres of the green class "A" compared to a "G" class can reduce fuel consumption by 9% [3] of a passenger car; even more for trucks.
The word tire is a short form of attire, from the idea that a wheel with a tire is a dressed wheel. [3] [4] Tyre is the oldest spelling, [5] and both tyre and tire were used during the 15th and 16th centuries. During the 17th and 18th centuries, tire became more common in print.
The markets predicted by the 2003 report were: tire derived fuel (TDF) using 130 million tires, civil engineering projects using 56 million tires, ground rubber turned into molded rubber products using 18 million tires, ground rubber turned into rubber-modified asphalt using 12 million tires, Exported items using 9 million tires, cut, stamped ...
Fuel produced from waste tires is known as tire-derived fuel (TDF). There is a potential for using waste tire rubber to make activated-carbon adsorbents for air-quality control applications. Such an approach provides a recycling path for waste tires and the production of new adsorbents from a low-cost waste material. [ 5 ]
On a typical vehicle, every extra 55 pounds (25kg) increases fuel consumption by 1 percent. [7] Removing roof racks (and accessories) can increase fuel efficiency by up to 20 percent. [7] Reducing on-board fuel to a lower value (50% to 75%) can also benefit fuel reduction in a town traffic setting ("VW Golf 8 online help".).
Oil derived from tire rubber pyrolysis contains high sulfur content, which gives it high potential as a pollutant and requires hydrodesulfurization before use. [16] [17] The area faces legislative, economic, and marketing obstacles. [18] In most cases, tires are simply incinerated as tire-derived fuel.
Of the tires that were scrapped, 43% were burnt as tire-derived fuel, with cement manufacturing the largest user, another 25% were used to make ground rubber, 8% were used in civil engineering projects, 17% were disposed of in landfills and 8% had other uses. [52]
