Tires

Scrap tire management has been a serious concern over the past decade.  Discarded tires are one of the most difficult auto repair wastes to dispose of. For many years the solution was to stockpile old tires in tire dumps. This has been going on so long that estimates of the number of tires stored this manner range from 750 million to 3 billion. An additional 250 million tires are scrapped every year, with a portion of these added to the tire dumps. Many of the stockpiles continue to receive more scrap tires each year. (See Tables 1 and 2 in Appendix L, for further information on scrap tire generation.) Since the first scrap tire law was passed in 1985, 49 out of 50 States have addressed scrap tire management through specific scrap tire laws and regulations or through State solid waste or transportation legislation.

 

 

Problems

 

Environmental Impact

Until 1985, most waste tires were buried in landfills or stockpiled at waste tire dumps. Tires are no longer buried at sanitary landfills, as they do not easily compact or decompose, and take up valuable landfill space.  Tires disposed of in this way present a potential fire hazard that could threaten natural resources by polluting air, soil and water.  Uncontrolled burning of tires releases toxins into the air, soils, and even groundwater.  State law prohibits the open burning of waste tires.  They burn very hot and are very difficult to extinguish. They may pose a safety hazard for fire personnel and others in the area.

 

Worker Safety

Discarded tires are an excellent breeding ground for disease-carrying pests and rodents.  Just one tire left outdoors can retain enough rainwater to breed hundreds of thousands of mosquitoes, which have been known to transmit two strains of encephalitis — La Crosse and western equine.

 

Regulations

Since 1991 all land disposal of tires has been prohibited by state law due to the many environmental hazards created by burying, dumping and the open burning of waste tires. 

 

Appendix M has information on California’s scrap tire management legislation and programs in a matrix for each program. It is intended to provide California’s regulators, as well as members of industry, with a quick reference on scrap tire programs.

 

The matrix for California’s program contains eight sections. The “State Contact” section provides general contact information of the scrap tire program manager for the California.  The “Legislation and Regulations” section briefly outlines the history of scrap tire legislation for the California. The “Funding Sources/Fees” section addresses the State funds and collection fees authorized by the State. The “Collector, Seller, and Hauler Regulations” section summarizes the regulations that apply to these entities. Similarly, the “Storage and Processor Regulations” and the “Disposal Restrictions” sections outline relevant regulatory requirements. The “Financial/Market Incentives” section discusses grants and other programs that foster better scrap tire disposal/recycling waste management and reduction. The “Additional Information” section provides information about activities of interest related to scrap tires in a particular State, such as special field tests or studies, and innovative uses for scrap tires.

 

Solutions

 

Waste Reduction

Prolong the life of your tires through proper maintenance.  You will not only save money, but also reduce the number of tires that need to be recycled.  Tires are designed to last up to 80,000 miles, however, most tire owners get less than half of this mileage out of their tires.  Proper tire maintenance improves gas mileage and provides better handling of your vehicle, saving you money.

 

Recycling

The Scrap Tire Management Council estimates that, in 1996, of the 266 million scrap tires generated in the United States, approximately 24.5 million were recycled for purposes such as ground rubber in products and asphalt highways, stamped products, and agricultural and miscellaneous uses. An additional 10 million were beneficially used in civil engineering projects. These civil engineering uses are presented separately from the recycling figure because, although some are recycled into products such as artificial reefs or septic system drain fields, many are used in landfill construction and operation. In addition, 152.5 million were combusted for energy recovery, and 15 million were exported. The remaining 64 million were landfilled or disposed of in either legal or illegal stockpiles.

 

The Reduce/Reuse/Recycle approach is slowing the rate at which tires are stockpiled. The design of all types of tires has advanced such that modern tires last considerably longer than those of just a generation ago; this has reduced the number of waste tires generated. Portions of the tires that are discarded are retreaded for reuse. Retreading is especially environmentally friendly with respect to energy conservation, since retreading a tire requires only about 1/3 of the crude oil needed to manufacture a new tire.

 

The bulk of the tires scrapped in the United States are recycled to recover their energy content. About 150 million tires are shredded and ground up annually to be burned together with other fuels in industrial facilities, including cement kilns, pulp and paper mills, and electric generating stations. A smaller number (about 25 million per year) are used to make floor mats, shoe soles, electrical insulators, racetrack surfacing, and as an additive for asphalt used in paving, among other products.

 

Most tire dealers will accept your old tires for a small fee.  Help protect the environment and pay the small fee to ensure that your tires are disposed of properly.  Check with the following for more information on disposal options:

Waste Management

When purchasing tires, consider purchasing the highest quality tire you can afford. High demand/performance tires likely incorporate more natural rubber, which has greater tensile strength, resilience and resistance to abrasions, impacts and temperature changes.
