other applications, so careful diversion and sorting are <br /> necessary to assure a market for diverted glass at this <br /> time. <br /> There may be other uses for glass which is not color <br /> sorted or which may contain contaminants. For example, <br /> some crushed glass is being used in road base material <br /> but those markets are hard to find. <br /> Table 4-1 lists quantity and diversion rates for <br /> various waste types diverted by recycling activities. <br /> The table includes information on waste currently being <br /> diverted and waste that will be diverted with <br /> implementation of the County's recycling program. <br /> IV. Other Recycling: <br /> Tires constitute a unique recycling issue. There are <br /> currently limited markets for old tires. That could change if <br /> improved technology makes it easier and less costly to <br /> incorporate tire material in asphalt for highway construction. <br /> At this time, the most efficient disposal method <br /> available in this area is to burn whole tires in WTE plants or <br /> in cement kilns. High combustion temperature consumes the <br /> tire and most resulting volatiles in both processes. In the <br /> cement kiln, any ash which remains is incorporated into the <br /> cement, reducing the need for iron and other raw materials. <br /> In the WTE plant, byproducts of combustion trapped in the <br /> baghouse system can be used as soil amendments. it is <br /> estimated that 25% of waste tires is reused, or recaptured in <br /> the transformation process. The other 75% is consumed as fuel <br /> in the transformation process and currently cannot be counted <br /> toward the 25% diversion goal for 1995. <br /> Chapter 4 - Recycling 7 <br />
