Followup to paving roads with rubberized asphalt.....asphalt with ground-up tires mixed in. This plant in Phoenix loads tires at one end, and they come out the other end as crumb rubber ready to mix with asphalt, or for many other purposes.

A Milwaukee based firm makes portable tire shredding equipment which can be towed or mounted on the back of a flat bed truck The tires can be cut into 1-inch chips, to be used as coarse aggregate or burned for fuel, or be taken somewhere else for further processing. The portable machine can process 400 tires per hour.

The same company also makes a compact indoor shredder which can process 600 tires per hour.

I found a buy/sell listing for crumb rubber. Apparently, there are two types of crumb rubber. The first is guaranteed no steel, in which the steel belts are removed before grinding. The process is slower. The list price is USD $300-$400 per ton.

The other is where the tires are ground up, and the steel magnetically removed, a faster process. The sale price is USD $150 - $200 per ton for massive quanities. For smaller applications, I saw an offer for $50 for a 50-pound bag.
