Expedition members said the number of expeditions this year means that there will be even more garbage next year because most expeditions do not abide by guidelines to bring down all their waste from the mountain. Of the trash that is now stacked up at the Nepal Army Base in Namche, 4 tons have already be taken down to Lukla and on to Kathmandu to be recycled by the group, Blue Waste to Value.

The expedition was jointly organised and funded by the Nepal Government, Safa Himal Campaign of the Nepal Army, Nepal Mountaineering Association, Sagarmatha National Park, Nepal Tourism Board, Sagarmatha Pollution Control Committee and the Pasang Lhamu Rural Municipality.

“There is still a lot of garbage up there, and it will take another 3-4 years of continuous cleanup to bring down everything and ensure that expeditions do not leave anything up there,” said Sangye Sherpa. “We have made a start to clean up, and I think this will send a good message across the world.”
