As ofabout million tires are discarded in the U. At the end of89 U. Only two dedicated tire incinerators are currently operating in the U. Another used to operate in Westley, CA but closed after a major fire. Another was proposed for Preston, MNbut was stopped in The number of facilities burning TDF is increasing.

What they fail to mention in their promotional materials is that tire incineration under any circumstance creates pollution that makes the air dangerous to breathe. It is common knowledge that burning tires in the open is extremely harmful to human health and the natural environment. The fumes emitted are packed with the many toxic chemicals that tires contain including volatile organic compounds such as benzene, metals such as lead, polycyclic aromatic hydrocarbons such as benzo a pyrene, and synthetic rubber components such as A look at problems posed by and styrene.

Additionally, the chlorine content in tires leads to the creation of dioxins and furans which are extremely toxic chemicals when tires are burned.

Yet, users of Tire Derived Fuel are confident that their machinery which usually is not even designed for burning tires and the combination of tires with traditional fuels like coal will render the incineration process harmless.

According to the Auburndale Recycling Center, Inca Wisconsin-based for-profit corporation that sells tire chips for incineration, "Most individuals are confused about the difference between a "burning tire" which emits black smoke and damages the environment, and the use of scrap tires as a fuel source for power companies.

Neil Carman and Dr. Schwartz have written in response to the "junk science" and stacked statistics behind the rubber-stamp approval of tire derived fuel.

These experts, along with other scientists, ecologists, and public interest groups, have uncovered the truth behind the propaganda -- that tire incineration by any method is NOT safe. However, there are many problems with this. First of all, the test data is not an accurate measure of the actual day-to-day emissions of a given plant.

As reported by Greenpeace, "Trial burns are generally considered a poor indicator of operation on a daily basis: On a day-to-day basis, emissions may be considerably higher. Neil Carman confirms this: It is unlikely that any incinerator could continuously operate for a long period of time at the same level of performance as it did during the initial testing period.

Another disturbing aspect of tire incineration, particularly in cement kilns, is the occurrence of serious "upsets. Carman explains, "Cement kilns certainly do have combustion upsets and smoke may be emitted during such events. Cement kilns are not designed or required to have major fail-safe combustion devices such as large afterburners that all state-of-the-art incinerators must have by federal law today all medical, municipal, and hazardous waste incinerators can not operate without their afterburner or secondary combustion chambers in normal operation.

The afterburner is required because of the potential for flame outs and total combustion failure in the primary burn chamber, which is all that cement kilns possess. Cement kilns have no fail safe combustion devices which is unthinkable today in all incinerators Cement kilns are subject to a variety of problems, including a type of meltdown of the kiln when the ID fans lose power or fail to operate, without adequate air flow to control kiln temperatures at or below 3, degrees F, the kiln temperature may skyrocket quickly to 4, degrees F and the kiln is so hot that the steel shell sags toward the ground effectively destroying the kiln.

Kiln meltdowns are not rare events and have happened here in Texas at several plants in the last ten years. Cement companies do not like to talk about this problem. As mentioned earliersuch reports have been repeatedly blasted by a number of reputable scientists and organizations.

These experts raise very serious concerns and cast a shadow of doubt over much of the "official science" behind tire incineration. Tire Incineration in Paper Mills The aforementioned EPA test was not even performed on an actual operating plant but rather on a scaled-down simulator.

Such devices are obviously bound to be more stable than large industrial incinerators that are used on a daily basis over a period of years. Importantly, the EPA simulator isn't even designed to represent the type of incinerators typically used in paper mills, which often use Tire Derived Fuel.

Tire incineration in paper mills poses special concerns. The North Carolina Division of Pollution Prevention and Environmental Assistance, a government agency that is generally uncritical of tire incineration as a whole, still has this to say about tire incineration in paper mills: Thus, complete burning of TDF particles in this kind of boiler is much more difficult.

Data have indicated that using TDF appears to deteriorate the emission quality. Particulates in the emissions are increased with a corresponding increase of TDF usage.

Other criteria pollutants also increased in most cases The emission control problem is the greatest single concern for burning TDF at pulp and paper mills.

Another major concern about Tire Derived Fuel is the enormous lack of knowledge about a wide range of potential dangers. This has been painfully apparent even in the pro-TDF reports.Background.

Problems with Test Data

What is "Tire Derived Fuel" and why is it dangerous? As of , about million tires are discarded in the U.S. every year (roughly one per person).
