Seems to me like the probability for scamming is nearly 100% in a program like this because there's a long chain of no-name contractors involved. One contractor hires another and says "Get rid of this stuff" and eventually one of them finds somebody who actually wants to illegally buy the usable part of the waste and then he just dumps the rest in a ditch somewhere. The next-to-last contractor in the chain didn't ask any questions about why the final contractor offered to cart it away for free, but they should have.

When the scam is eventually discovered, the publicly-visible company at the front of the chain has plausible deniability and blames it on the contractors. This general pattern is what caused a decent fraction of EPA superfund disasters in the US.

Plus it's waste, so nobody is very motivated to actually keep track of where it ends up. Until bluetooth trackers came along and made that easy, anyway.
