 go to this link:

http://www.friendsofhudson.com/news.html

for information on the Lafarge proposal to burn tires at their Ravena plant and the Friends of Hudson response

For additionjal information on the burning of TDF (Tire-Derived Fuel) here are a few links to get your research started:

and
Tire Recycling

Happy learning!

"TDF is a very high quality fuel having about 13,000 to 15,000 BTU per pound, (7200 to 8300 kcal/kg), about the same as a superior quality coal. TDF typically has 0.5-2.0% sulfur, this is less than or equal to most coals and coke"

Looks like there is little difference between coal and tdf, tdf being a bit better. Ct. burns tires in their power plant.

A few sites you can check out.

I think we should all get all the info we can. CT is generally good about environmental issues - so I'm interested to see what they have to say. I'll follow up on this - as I hope you will on the sites to which I provided links.

Thanks. The more we all know, about all the arguments, pro and con, the better decision we'll be able to make.

Gene -

Do you find it curious that neither of the sites you offer has any discussion of any possible health effects of stack emissions from such facilities? Neither of these sites recognize or acknowledge that there is any possibility of serious health consequences (which are well-documented in scientific studies cited on the sites I offered) in the emissions from such facilities. Does total avoidance of the whole subject seem a "balanced" approach to the issue to you?

Is it also worth noting that the first site - the GCI site - is prepared by a professional consulting firm hired by the cement industry? Do you think it likely that such a firm can be truly objective about the pros and cons of tire burning? Should we give their analysis the same weight we give to that of independent experts?

The CT State site makes a point that the tires-to-energy plant is the ONLY facility in the State licensed to burn TDF - and that it is an incinerator dedicated to the safest possible burning of such materials (not a plant whose main purpose is something other than safe conversion of TDF). It is also located on the Connecticut shore, where any harmful emissions are generally carried out to sea by the prevailing winds.

Certainly we have a problem with the disposal of used tires. There are many strategies for dealing with it - from incineration to various kinds of recycling. Some work better than others and some produce more pollution than others, in more dangerous forms and more widely dispersed.

This seems to be one of the major problems with cement-kiln incineration. Because of the variable nature of the burning process in the cement-kiln's primary purpose, ideal conditions for tire incineration can't be guaranteed - which leads to the likelihood of more pollution being released than would be by a dedicated tire-incineration plant.

Then, the location - in Ravena - of a plant burning TDF in an air corridor that covers some of the East Coast's most populous regions means that whatever dangerous pollution is released would be distributed over a significant population - numbering in the tens of millions. Does this seem like a good idea to you?

I hope you get a chance to read the material I cited. Please let me know what you think.
