Waste Management (the company) and vintage computers...

Anyone had any dealings with them in this regard? I expect that they run a lot of local landfill sites (at least here in the US, but I think they're a global company). I've got a contact at my local one who tries to set aside for me anything that they think I might find interesting, but management policy is that nothing can leave the site once dropped off, and it sounds like this rule will be more strictly enforced in a couple of weeks' time following a site audit. I was considering contacting their management to see if there's any way to officially secure vintage items, and was wondering if anyone else has done this successfully? (In particular, it would be nice to know ahead of time what their main concerns are - if it's a liability issue, say, or if they perhaps see monetary value in e-waste) cheers Jules
