Dang. I forgot about the strenuous part of the trek. And, I don’t think WasteManagement picks up in the area either.
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.
