When possible, recycling is the preferred method of disposal. This may include integration of tires as crumb rubber into asphalt for roads, or other civil engineering products.
A major benefit to substituting tire shreds or chips for traditional gravel, stone, or soil is that the unit weight of tire chips is substantially less, reducing transportation costs and increasing the ease of placement in many cases. House foundations and septic system installations are also current uses for waste tires but the potential quantities are smaller.
While many tires in the region are currently incinerated for fuel, a process known as tire-derived fuel (TDF), and tires can replace other fossil fuels in this process, this does not truly represent recycling and carries harmful impact to the environment in the transportation and burning of tires.
According to the Scrap Tire Management Council, there is a reluctance to incorporate used tires into new tire production due to the public’s perception that tires with a recycled content would be less safe than tires made completely from virgin material.
