There is evidence of tires contributing to the presence of mosquito-transmitted diseases. The main solution that has been offered is tire shredding. This guarantees that no water will be held for breeding sites. Further preventive measures could include requiring all shipped tires and all stockpiles to be fumigated. Other solutions sometimes suggested to the mosquito problem in tire stockpiles... 

If stockpiles for waste tires are carefully monitored, the fire hazard can be reduced. Shredded tires pose less of a threat for fires. Tire shreds behave differently than whole tires when burning and because they have less air space, they can be extinguished more easily by allowing water to smother the fire (4). Other precautions that may reduce the fire hazards of tire stockpiles are mandatory fire lanes and fire plans so that a fire can be attended to as quickly as possible (3).

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. 

HI None Draft statewide solid waste aianagement plan does not address tires. Honolulu County plans a scrap tire managsawnt program that would provide for tire shredding for sale to Honolulu Power. 

The pilot plant is shown in Fig. 3. The longest period of continuous operation of the pilot plant was 120 hrs. In the mini plant tests (MP Test) scrap tires shredded into pieces about 10 mm in size were used. In the pilot plant tests (PP Test) scrap tires shredded into pieces about 50 mm in size as well as the fine shredded tires were used. 

Work has been done in a number of states using tire shreds as a subgrade fill in the construction of highway embankments and other fill projects. Tire shreds weighs considerably less than conventional soil fill and this allows construction on weak compression foundation. The use of tire shreds for most projects is considerably cheaper than alternatives, such as expanded shale aggregate and polystyrene insulation blocks. Scrap tire materials have also been used to retain forest roads, protect coastal roads from erosion, enhance the stability of steep slopes along highways, and reinforce shoulder areas. The importance... 

In northern climates, one of the problems affecting roads is the water released when the subgrade soils thaw in the spring. To prevent this, tire shreds are used as subgrade insulation. The insulation provided by a 6-12 in. layer of tire shreds keeps the subgrade soils thawed during the winter. Tire shreds also allow excess water to drain from beneath the road. ... 

Several projects have been constructed using tire shreds as backfill for walls and bridge abutments. The weight of the tire shreds produces low horizontal pressure on the wall allowing thinner walls at lower cost. Another advantage is that tire shreds provide better drainage and good thermal insulation, which eliminates problems with water or frost buildup behind the wall. ... 

Many landfill operators have found that scrap tires can be used beneficially in the construction and operation of the landfill. Tire shreds are used in building leachate collection basins in new landfills and they can also be used as the drainage layer in landfill caps. Another application is mixing tire shreds with soil as daily cover material. 

I m sure you ve seen movies and TV shows where road blocks are put up and the villain or hero crashes right through and gets away. This is for effect, as decently equipped police departments have portable road blocks studded with over siied spikes. For P.D.s who can t affort these or need to stop traffic immediately without calling in, you can t beat my tire shredding road blocks. They can also be used by civilians to teach trespassers the error of their ways. 

Finally, it would be useful to cite the Annual Buyer s Guide to Tire and Rubber Recycling Equipment [66], which contains contact details and brief product information for more than a hundred companies, most North American, including manufacturers of primary and secondary tire shredding eqnipment, knives, and granulating and pulverizing systems. 

The production of tire shreds or tire chips involves primary and secondary shredding... 

The shredding process results in exposure of steel belt fragments along the edges of the tire shreds... 

Tire chips are more finely and imiformly sized than tire shreds, ranging from 76 mm down to approximately 13 mm in size. Although the size of tire chips, like tire shreds, varies with the make and condition of the processing equipment, nearly all tire chip particles can be gravel sized. The loose density of tire chips can be expected to range from 320 kg/m to 490 kg/m and their compacted density from 570-730 kg/m. Tire chips have absorption values that range from 2.0-3.8%. 

The main chemical characteristic of tire chips and tire shreds is their nonreactivity under normal environmental conditions. The principal chemical component of tires is a blend of natural and synthetic rubber, but additional components include carbon black, sulfur, polymers, oil, paraffins, pigments, fabrics, and bead or belt materials.

There are basically two types of tire shredding equipment in conunercial use, the solid cutter shredder and the replaceable cutter tire shredder [18,19]. Both of these machines shear a whole tire to produce a chip with a fixed size in one dimension, but to control the oth chip dimension, additicmal passes through the chipper may be required. 

Processing costs for a tire shredding operation will vary depending upon many factors, such as feed material, throughput, system being used (portable vs stationary) site conditions, preventative maintenance program, disposal options, power available and local markets, desired end product, geographic location.
