Trash collected from Mount Qomolangma, commonly known in the West as Mount Everest, is set to be transformed into art and displayed in a nearby gallery, to highlight the need to save the world's tallest mountain from turning into a dumping site.

Used oxygen bottles, torn tents, ropes, broken ladders, cans and plastic wrappers discarded by climbers and trekkers litter the 8,848.86 meter tall peak and the surrounding areas.

Tommy Gustafsson, project director and a co-founder of the Sagarmatha Next Centre - a visitors' information center and waste up-cycling facility - said foreign and local artists will be engaged in creating artworks from waste materials and train locals to turn trash into treasures.

"We want to showcase how you can transform solid waste to precious pieces of art … and generate employment and income," Gustafsson said.

"We hope to change the people's perceptions about the garbage and manage it," he said.

The Centre is located at an altitude of 3,780 meters at Syangboche on the main trail to Qomolangma base camp, two days' walk from Lukla, the gateway to the mountain.

It is due for "soft opening" to locals in the spring as the number of visitors could be limited in 2021 due to pandemic restrictions, he said.

Products and artworks will be displayed to raise environmental awareness, or sold as souvenirs with the proceeds going to conservation of the region, he said.

Trash brought down from the mountain or collected from households and tea houses along the trail is handled and segregated by a local environmental group, the Sagarmatha Pollution Control Committee, but the task in a remote region that has no roads is a huge challenge.

Garbage is dumped or burned in open pits, causing air and water pollution as well as contamination of soil.
