Hundreds of mountaineers from all over the world attempt to climb Mount Everest and other Himalayan peaks in Nepal.
But activists say over the decades tonnes of disposed tents, spent oxygen cylinders and discarded food containers and bottles have been left behind by various teams in the pristine snow clad mountains.
Many inexperienced climbers discard rubbish along the way to save the energy they need to reach the summit or return to base camp safely.
Now the Nepalese authorities are urging the mountaineers to bring their disposable waste back to the capital Kathmandu, so that it can be recycled.
Anbarasan Ethirajan visited a recycling yard in Kathmandu dedicated to waste from the mountain.
