MEBP: PROJECT BACKGROUND
Mt. Everest boasts a massive climbing industry, with hundreds of climbers making the trip up the Khumbu Valley each year. This tourism, which has led to significant financial gain for the Nepalese, has also left a trail of human waste that has given way to environmental and public health concerns.
MEBP proposes to use an anaerobic biogas digester to treat the human waste, and outlines the project management solution to do so. The biogas digester will eliminate dumping of solid human waste at Gorak Shep and destroy pathogenic fecal coliforms that threaten the health of the local communities – lessening the impact of the tourism industry on a mountain that is sacred to the Nepalese. Initiated in 2010 in affiliation with Engineers without Borders and Architects without Borders, the MEBP system technology has been designed and tested and the team has brought the project to construction-ready. Groundbreaking is planned for spring 2018 and an operational date slated for winter 2019.
“We have strong support from the Nepalese organizations along with the Gorak Shep tea house owners,” adds Porter in relation to the project’s next steps. “Our engineering and architectural design is sound: and we have high confidence in it. It is now time to put theory to test.”
Each year, thousands of climbers and support staff populate Everest Base Camp for several months during the climbing seasons, producing approximately 12,000 kg of solid human waste. In 1991, the Sagarmatha Pollution Control Committee (“SPCC”), was created with the responsibility for protecting the environment of Mt. Everest. Since then, SPCC has developed waste management strategies for the removal and disposal of human trash. However, there has been no viable solution of how to deal with human waste. The current practice is to pack it down to the nearest teahouse village of Gorak Shep from base camp in barrels and dump the waste into open pits, just above the flow of the Khumbu Glacier that feeds the lower valley. The untreated waste in these unlined pits poses a danger both to the environment and to the public health of the Sherpa people who live in the region.
The Mt. Everest Biogas Project will address this environmental and health hazard in a sustainable manner and serve as a model for other regions that must deal with similar waste problems at high-altitude, regardless if it is caused by climbers or local communities. When implemented, MEBP will: eliminate the dumping of solid human waste at the teahouse village of Gorak Shep; reduce reliance on burning wood or yak dung for heating and the resultant respiratory and ocular health risks; reduce deforestation of the areas limited wood resources; and reduce risk of water contamination by fecal coliform. The system will convert waste into methane, a renewable natural gas, and a reduced pathogen effluent.
With funds raised through the MEBP, this project will build the first operating biogas digester in a cold climate. Once the biogas digester is established and running in the Khumbu valley, the design will be made available to the public so that other similar mountain climates in need of a sustainable waste management system can use this design in their own replications.
“The fact that this is an all volunteer design team compounded the challenge,” explains Porter. “Everyone on the team believes that they can make a difference, but they all have a “real life”: a demanding job, family and friends and a life outside of work. My previous experience in program management did not prepare me for the necessity of nudging, coaxing and sometimes pleading to keep the project moving forward. And yet, some of these same volunteers have spent seven years on the project. We could not have done it without their time and talent.”
This human element of teamwork and commitment has been crucial to the project’s success and Porter’s advice for aspiring projects is to: “Find the best people who truly believe in what you are doing and never ever give up. Provide the vision of what you want to achieve and let the team members use their talents to achieve it. There will be many obstacles along the way, but the people you meet will all share the same vision. The mountains with which our planet has been blessed must be protected and preserved.”
