slightly ot, was re: chemicals

I've wondered for years why old tires were not ground up, the steel removed with magnets, and the rubber mixed with crude oil at the refineries.

I can't find the reference, but in the last couple of weeks I came across a story about a guy who took old tires, and built a fence in a rural area with them, and ran into all kinds of legal troubles because of the laws regarding the "disposal" of tires. I wonder how often recycling efforts die not because the technology isn't there, but because the laws are inflexible, and the folks who could change them don't care to change them?

Does anyone else besides me think that Warren is the next unibomber in the making?

In Europe, I've heard that they're mixing ground up old tires in asphaltic concrete for road surfaces, with really good results.

This page has a good deal of general information on tire recycling.
