Are you sure there will be nothing left in a month? In Kalle Bunte's
technical note [1], the dispersion of GTO fragmentation clouds needs
more than one year. I think that the surprise for all of us on that ESA
contract was the the debris clouds remain in orbit for much longer than
people thought they would.

I wrote a bunch of notes on the topic on Bee's and Stefan's backreaction
blog here:
