Correct me if I am wrong, but, I thought that the old tires, rubber from shoes, etc, was now beeing used as covering for ground in playgrounds!
There are a few playgrounds that have a really nice bouncy feel with different colors and such---
Wouldn't that be a better idea than burning them?
On this idea we had we were at war with a part of the PA DEP -- in the course of events the DEP shut down at least one plant of someone who dared try something like we were doing (a precursor idea) -- about a dowen people lost their jobs, the plant was padlocked and the the PA DEP reached down into Delaware to have that state's DEP bring charges against a farmer who was that state's ex-Ag Secretary. Given that background, we roped in the PA Lt. Governor and some other key political alliances before we even showed a few cards from our hands. Even then we tapped out on start-up $$. Close only good in horseshoes. One of us even tripped down to Arkansas and met with the Tysons -- he came back all pumped up about some Bill Clinton, who at that time was a dark horse candidate in the Dem primary.
Anyway I learned that you can work around the regulators if you employ some ground leveling political tools long before you show your technology hand.
