I doubt Waste Management does, but maybe Himalayan Adventures or Bob’s Mountain Experiences should. They charge a king’s ransom for “guiding and provisioning” services. When I go to a hotel, I don’t expect to have to wash my own towels. And these outfits charge a lot more than any 5-star hotel.
Better yet, let the governments of Nepal and Tibet pay Sherpas police the trash. You have to buy a very expensive permit to try an Everest summit. Let them pay some of the locals from the proceeds.
Find a way to float it out of there. Yes it will land somewhere sometime but probably be easier to dispose of at a lower altitude.
The people finding all that trash may actually be able to use the metal for something.
Hire sherpas to carry in hot air balloon like devices that can be used to lift the trash out of there and where ever it falls later the locals would probably be able to use it for something.
Just a thought. Probably went over like a Lead(Led) Zepplin.
