Used Tyres (as I thnk you wished to spell it) requrire a prohibitive amount of energy to recycle into component prodects (petrol, steel, &c), adn furthermore all processes that do so are sinfully polluting. Shredding and recycling into composite building or road surfacing products is a much better option. Sorry to rain on your parade.

Are we able to burn them and get the exhaust gases cleaned up in some economical way as of now?

Are there any better systems for dispersing/using of all this oil locked into rubber?

Hi Andy, In the 1980s a UK company (Tarmac) in Wolverhampton applied for permision to burn tyres in an incinerator to produce electricity. The system worked better than most people thought it would, but their biggest problem was getting rid of polution in the exhaust gasses, so they had to shelve the idea. They found that the problem of incinerating tyres produce a lot of PCB's, Hydrogen sulphide, dioxins and Carbon dioxide, all of these polutants are very hard to clean up. There was a suggestion put forward that the exhast gasses from this procedure could be passed through a condenser and cooler to collect them in liquid form, but the problem then was what to do with these waste products.

Actually a great number of old tires have been used in the US for fuel for power generation and in cement kilns. There is a problem from a court case that may stop the use of tires for fuel. There are several environmental groups against it. I have no idea if their fears are justified or not but a negative ruling may mess up the entire recycling industry for crumb rubber as it would mess up the economics.

Economical separation I think continues to be an issue. I had a friend who a few years back worked on a project to use liquid gas (either N2 or CO2?) to make the tires (sorry, thats how we spell it on this side of the pond) brittle and allow easier separation. After a few months work and study, the project ended with both economic and technical problems. This was well before oil was US$ 70-80 per barrel, so economics may be different now.

I agree that product recovery and reuse is more desirable that energy recovery, and believe it is a matter of enough time and thought to make it feasible.

You should also try using the spell checker yourself, reread what you wrote, the right letters, but in the wrong order!!!! Six spelling mistakes (the spell checker finds only 5!) and a bit of mixed up grammar.....you rained on your parade too......maybe the parades were on the same day in the same town?

Your fingers are faster than your brain, or what is or means exactly the same, but sounds much worse, your brain is slower than your fingers.....

Tyres is the British spelling and Tires is the US spelling.....I believe. Spell checker only likes the US spelling!!

Everyone jumps down my throat when I ask people to spell correctly, and its mainly to help our overseas cousins who do not have English/American as a first language.....

The spell checker is easy to use and helps to improve at least our spelling....grammar is another less of a problem I feel....

Have a great day whatever time it is with you!!!! Don't forget your Brolly!!

Absolutely no problems on that score!

But thanks for the friendly warning, I agree that many people do get upset easily on CR4, and maybe drive the old blood pressure up unnecessarily, I personally find that to be rather negative.....

....the same way as I find bad spelling to be a simple problem to fix if the spell checker is used. It makes people look particularly silly, especially when people misspell a post complaining about misspelling!! Which was the reason for my post, or maybe you did not see the other letter in question?

In fact, it was almost recursive! In a silly way.......of course!

Have a great day.

I have heard very little lately regarding used tires as fuel. However the use of same as filler is being expanded. Fill er in concrete, asphalt and for use in roofing and atheletic courts and childrens play areas are a few I am aware of.

A problem in the US when I followed tire recycling more closely was separation of the steel cords from the rubber crum. I hate to think of kids running around where broken steel cords are lying about.

Of course, by now that issue might be solved.

we should all keep away from burning things for energy even burning wood releases harmful gases. Fires can prod. a number of diff. gases, including some that are harmless and some that are toxic. Carbon dioxide (CO2) and water vapor (H2O) are two relatively harmless gases prod. by fires. Toxic gases from fires include carbon monoxide (CO), hydrogen cyanide (HCN), sulfur dioxide (SO2), and hydrogen chloride (HCl). -MSN Encarta Encyclopedia

i agree with ktel60 & C Rummel3. i saw on an educational tv show that they are using used tires to make sidewalk panels (or sections) about 2'x2' squares, they installed them in either Santa Monica, California, USA or Venice, California, USA.

the lighter/brighter the color the better so as to reflect more sunlight- we've lost a lot of white/bright on earth (melting glaciers & snow), compounding the warming of earth.

good luck

two days ago i saw on the news that the Orange County Transportation Authority (Orange County, CA) is conducting a test project using rubberized asphalt to reduce traffic noise.

they might also be used to make anti-fatigue mats (those that interlock to each other) used where people stand a lot at work (cooks, manufacturing, gyms,etc.)

Hi kmbjdjn, Here in the UK they have been doing just that for the past 25 years. Mixed with aspfalt it makes for a smoother ride while cutting down on polution. Anti-fatigue mats, every lathe and machine operator in the UK has been using these mats made out of old tyres for years, they are great for relieving fatigue and strain. Spencer.
