Climbers have turned Mount Everest right into a high-altitude landfill, but sustainable solutions are within sight

Spring is the time for climbers who wish to climb Mount Everest, the best mountain on earth above sea level. Hundreds of mountaineers They travel from all around the world to Asia in April and May and head for base camps in Nepal and Tibet.

But it's not only rugged peaks that will likely be seen. Especially on the more heavily crossed Nepalese side of Everest you can see fields of garbage – including cans, bottles, plastic in addition to human and animal excrement.

More than 60,000 hikers and climbers visit every year Sagarmatha National Park and Buffer Zone, a high-altitude a part of the Khumbu region in northeastern Nepal that features Everest and 7 other peaks. Every 12 months around 400 to 500 climbers try to climb Everest.

The garbage problem became clear for the primary time within the Eighties and Nineties, when mountaineering and trekking within the Khumbu began to extend. Numbers of mountaineers and trekkers have continued to rise sharply over the past 20 years.

Most coverage of this issue focuses on negative and sensational facets, corresponding to: frozen bodies of climbers who remain on the mountain where they died since the removal measures are dangerous and expensive.

We are scholars who Study geosciences And Geography of the mountains, and certainly one of us (Alton Byers) lived in Nepal and worked with communities around Everest. We are encouraged to see increased efforts to deal with the huge trash problem on Everest. We imagine modern technology and international collaboration are key to ending the piles of waste on this iconic environment.

Pollution from waste

For most visitors to this region of the Himalayas, Everest Base Camp is situated within the upper reaches of the Himalayas rapidly retreating Khumbu Glacier is the last word destination at an elevation of 17,589 feet (5,364 meters). It was a two to a few week trek from Kathmandu, but today the journey most probably starts there Lukla airportwhich is roughly 35 miles (60 kilometers) from base camp.

Climbers who want to succeed in the summit of Everest often spend money as much as two months on the mountain, including weeks of short, gradual climbs over base camp and back again. This allows them to acclimate to the altitude before climbing to higher camps after which to the summit.

Much of the food and equipment transported to Everest also begins its journey in Lukla. Some will likely be transported to base camp by helicopter, but much of the equipment will likely be transported there by plane Yaks, yak/cattle mixes called Dzopkio, mules and horses.

Quite a lot of equipment, food and packaging in addition to animals and porters means plenty of waste. A 2010 study estimated that park tourism generates 4.6 tons of solid waste per day during peak tourist periods in April-May and October-November.

Ultimately, most of this waste is dumped in unsightly landfills near surrounding villages. There it’s burned, releasing particles and toxic chemicals into the air. The remaining ash is buried and may contaminate the groundwater.

Microplastics were found at the bottom camp – probably from discarded mountaineering clothing, tents, ropes and boots in water and snow samples. High levels of perfluoroalkyl and polyfluoroalkyl substances (PFAS), widely generally known as “forever chemicals,” have been detected found on the Khumbu Glacierprobably made out of materials used to waterproof climbing boots, tents and clothing.

These substances could pose a health risk to hikers who’re only climbing temporarily, but pose a more serious threat to individuals who live a lot of the 12 months within the nearby settlements of Gorak Shep, Lobuche, Dugla and Pheriche. Some of those villagers work at Everest Base Camp and are also exposed there.

And then there may be wastewater. Most of the septic tanks within the lots of of lodges are situated throughout the national park and buffer zone Leakage that further pollutes groundwater. Camp Four, the last place mountaineers occupy before attempting to climb Everest, is covered with garbage and frozen, windswept feces.

National parks in developed countries have infrastructure for waste management, garbage collection, recycling, and wastewater treatment. At Everest Base Camp there are only collection barrels under toilets. About 50,000 kilos (22,000 kilograms) of human waste is brought there every year Garbage dumps several kilometers away.

Solutions for sustainable tourism

Given the magnitude of this problem, initiatives are underway to develop solutions.

The Sagarmatha Pollution Control Committee, founded in 1991 by local Sherpa people, is an indigenous non-profit organization accountable for monitoring trash within the permit-requiring mountains and peaks. The group focuses on garbage control and regular clean-up work at the bottom camp.

In 2014, the Nepalese government began requiring every climber who climbs Everest Base Camp to achieve this Return 18 kilos (8 kilograms) of solid waste from the mountain or lose a $4,000 deposit. Of course, in case you paid $75,000 or more for the trip, losing the deposit isn't much of an incentive. Many people decide to forego it.

A nonprofit organization called Sagarmatha nextFounded in 2019, the corporate is committed to promoting sustainable tourism within the Khumbu region and works with corporations and organizations from world wide. The group has been raising awareness by creating artwork and souvenirs from trash. A “Carry Me Back” program has also been launched, encouraging tourists to take two-pound (one kilogram) bags of solid waste, corresponding to shredded plastic bottles, to the Lukla airstrip for processing and disposal in Kathmandu.

At the request of the local government, the University of Colorado Boulder was created a sustainable waste management plan in 2019 for the national park and the buffer zone. The COVID-19 pandemic delayed the implementation of the plan, which calls for the creation of a five-stage process: waste separation, collection, sorting and shredding, transfer to shipping stations and transport to recycling facilities in Kathmandu.

Another non-profit initiative that NeverRest Projectwas founded in the course of the pandemic to supply environmental solutions for Mount Everest and other fragile ecosystems world wide. NeverRest is working with the Nepal Tourism Board to revolutionize waste disposal at high altitudes using modern technology.

In 2023, the organization presented an idea plan for a sustainable Everest base camp that may install technologies corresponding to portable solar tents to cut back fossil fuel use; Portable unisex urinals with multi-purpose filters that convert urine into water; incinerator toilets that turn human waste into ash; and modular geodesic dome tents designed for effective heat retention to cut back energy consumption.

In the 71 years since Sir Edmund Hillary and Sherpa Tenzing Norgay did it first known successful ascent of Mount EverestThis peak has been the scene of courageous expeditions, triumphs and tragedies. We hope the region's waste problem will soon fade into history as recent approaches and technologies provide solutions for Everest and other distant high mountain locations world wide.
