Have this disposed of correctly.
There's a good reason it is expensive to have done - it takes a lot to do it properly and ensure that nothing contaminates the earth!
Come on! Where are all the hippies!?! I'm only 26, i shouldn't care about this sort of thing!
It doesn't matter much if a bit of oil does contaminate the earth (water courses are a different matter, as is a lot of oil) as bacteria will sort it out. The residue in a drained tank is probably less of a problem than the oil dripping from cars parked in a supermarket car park over a week.
