Tire Recycling Information (Science Memo)

TIRE RECYCLING INFORMATION

In many countries, tires from cars and trucks are piled on landfills, with potential for fueling a dangerous fire that is difficult to extinguish and highly polluting. Below is general information about tire recycling and links to many valuable websites.

Definitions:

---Crumb rubber is rubber that has been shredded and reduced to a particle size of 3/8 inch or less.

---Tire-derived fuel (TDF) is when scrap tires are burned for energy, as a substitute for fossil fuels. The average 20 pound passenger tire contains 280,000 British Thermal Units - the equivalent of 2.5 gallons of oil or 20 pounds of coal. TDF is used most in cement kilns and paper mills, some of which get 15% of their energy from TDF. When done under controlled conditions, tires can be burned safely- below are links to studies showing that the emissions released by TDF are within regulatory limits.

TDF shouldn`t be confused with the open tire fires that occur in tire dumps, which sometimes make national news. When a tire dump with millions of tires catches fire, it can take weeks and millions of dollars to extinguish it. Open tire fires give off clouds of black smoke and release a disgusting runoff that can get into groundwater.

This is the European Recycler`s Exchange, where companies can place a free listing when they want to buy or sell anything recyclable. Click `Non-Metallic Materials Recycling,` then you`ll see 6 listings under `Tyre.` Click any of them and you get a breakdown of products available. Click any of them, then click `View Listings.` Companies that want to buy or sell that product will be listed. If it says `No exchange items currently listed, ` that means no companies want to buy or sell that item right now.

Safety and emissions of burning tires for energy:

Tire-derived fuel (TDF) is when scrap tires are burned for energy, as a substitute for fossil fuels. The average 20 pound passenger tire contains 280,000 British Thermal Units – the equivalent of 2.5 gallons of oil or 20 pounds of coal. TDF is used most in cement kilns and paper mills, some of which get 15% of their energy from TDF. When done under controlled conditions, tires can be burned safely- below are links to studies showing that the emissions released by TDF are within regulatory limits.

TDF shouldn`t be confused with the open tire fires that occur in tire dumps, which sometimes make national news.

Open tire fires give off clouds of black smoke and release a disgusting runoff that can get into groundwater.

Dozens of studies of the emissions released by companies that burn tires. All the studies I looked at conclude that the emissions are safe. Some even found that hazardous emissions decreased when tires were burned with coal. When you click these links you`ll see info on purchasing the studies, but if you click `Download Now` they`ll download free.

The best thing to do with used tires is put a new tread on them and use them again.
