Whole Tire Disposal

There are no known whole tire disposal methods without adverse effects. Disposing of the tires above ground creates the hazards of mosquitoes and fires. The alternate disposal method is landfilling or burial, which is also not without problems. In landfills, tires require a large volume because about 75 percent of the space a tire occupies is void. This void space provides potential sites for gas collection or the harboring of rodents. Some landfill operators report that tires tend to float or rise in a landfill and come to the surface, piercing the landfill cover. 

Haul costs depend on many factors, including truck size, distance hauled, local labor rates, etc. For semi-truck loads of 1,000 whole auto tires hauled over 100 miles, typical costs are in the 15 to 20 cents per ton-mile range. This is equivalent to 15 to 20 cents per 100 tires per mile. Shredding can reduce this cost by 30 to 60 percent.

Some ol the states allow tor storage (above ground) ol shreds at landfills. OH, NC, CO are among the states considering or allowing monofills for tire shreds. Whole tires are discouraged from landfills (in almost all cases) either by taw (e g.. MN) or more frequently by high disposal lees. 

Haulers may be paid from 0.35 to 5.00 to dispose of whole tires.1 In general, the cost to landfill whole tires is double the cost to landfill mixed munic -jal solid waste. 

Landfill Whole tires create problems in landfills, but shredded tires do not. They take up less space, do not readily burn, and do not provide habitat for mosquitoes. Landfilling of tires is a poor alternative to the options presented above and is simply disposal with no intent to get any value from the tires. 

Several decades ago, attention had already been called to the very complicated nature of the entire disposal problem [3]. It has been said that the whole field of scrap-tire disposal is full of alternatives, compromises, legislation, and conflicting reports on technological success. An ideal solution would have to be based on following ... 

A very simple method of reusing old tires in landfills could have been a possibility. But in Europe, the Landfill Directive has banned the disposal of shredded tires in landfills since July 2006. It should be added that whole tires have been banned from landfills since 2003 [11]. Elsewhere, a high court directive [65] did not permit burning of scrap tires as a substitute fuel in cement kilns for pollution reasons. 

In summary, cement kilns appear to offer an excellent market for the disposal of waste tires. At present only two plants burning tire chips and one burning whole...
