Trash to treasure: Mt Everest garbage given new lease of life

Mount Everest has been dubbed world's highest rubbish dump.

A group of tourists sip water at a five-star hotel in Kathmandu, unaware that the green glasses in their hands were once bottles discarded on Mount Everest -- left by climbers eager to make their ascent.

In homes across the Nepali capital upcycled items, from pots to lamps, crafted from Everest waste products are slowly making their way as authorities and businesses look for fresh ways to tackle the damage caused by decades of commercial mountaineering.
