Tire disposal

Tire disposal costs are 0.10—3.00 per tire. Cost for incineration without heat recovery is 0.35—0.70 per tire. Transportation of discarded tires can cost 0.04/kg, and size reduction can cost 0.20—0.60/kg. Distribution of passenger car tires is landfill, 85% retreaded, 10% and reclaimed, burned for fuel, and spht, 5%.

Tires discarded in landfills tend to float on top of the ground mosquito infestation and illegal tire disposal cause problems which can be alleviated by recycling. Approximately 45% of scrap mbber, primarily as tires, is discarded in landfills (2). Private landfills may charge up to 3 per tire, and disposal costs at municipal landfills are ca 0.30—0.60 per tire (3,4), encouraging illegal disposal. As the tire piles grow, mbber recovery becomes more economical...

It is commonly accepted in the tire industry that about one tire per person per year is discarded. Since there is no industry group or governmental agency that monitors tire disposal in the United States, the best estimates that can be made are based on tire production. The Rubber Manufacturers Association (RMA) records the number of original equipment, replacement, and export tires that are shipped each year in the United States. (See Table 3.) In 1990, a total of 264,262,000 tires were shipped. The RMA data include new tire imports, but not imported used tires. To estimate the number of tires that were discarded in the United States in 1990, the following assumptions were made ... 

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.

In 1990 OMNI used at least 14 million pounds of crumb rubber for railroad crossings. Another company, Park Rubber Company of Illinois, used less than 1 million pounds of crumb rubber for the same purpose. If 20 million pounds were used for rubber railroad crossings, this would be equivalent in weight to about a million scrap automotive tires. However, if only buffings are used, only about 10 percent of each tire is used, and the tire disposal problem is. not solved. 

In the past three years there have been major increases in the utilization of waste tires as a fuel. Applications have included power plants, tire manufacturing facilities, cement kilns, and pulp and paper production. These applications have demonstrated the capability to extract energy value from the tires in an environmentally acceptable manner, while at the same time alleviating tire disposal problems in their communities.

Economically, the advantages of TDF can be very site-specific. Primary, or base load, fuel costs vary significantly, as does the delivered cost of TDF. TDF supplies a consistent and dry Btu input to boilers. This is an important advantage because the wood wastes typically fed to the hog-fuel boilers have a high and variable moisture content, which makes hog-fuel boiler operation a challenge. Availability of TDF is a problem at some mills. The costs of TDF -to a pulp and paper mill is affected by whether there is a tipping (tire disposal) fee or State rebate incentives...
