The issue of global warming or also called the greenhouse effect (Greenhouse gas emission) is an interesting discussion to continue to follow his progress. The reason, the impact of global warming very pronounced for the survival of the entire creature on Earth. One of the factors the onset of global warming is human negligence towards nature, namely litter.
Who doesn't know Mount Everest? One of the highest mountain in the world and the beauty of panoramanya makes a lot of people (especially nature lovers) who wants to conquer the mountain. More than 26,000 climbers every year visit to Mount Everest. Cannot be denied more visitors will be getting many impurities that accumulate, be it trash or human feces. More than 26,000 pounds of human waste generated from camp-camp climbers. This State can be harmful to the environment around the mountains, especially for the health of residents around Mount Everest. In 2012 the research of the World Health Organizatiton (WHO) declared that the source of the springs in the mountainous regions i.e. Gorak Shep has violated four rules of decent drinking water standard.

Typical Analysis For Digester Biogas
Utilization of Biogas as an alternative energy source has a lot to do. Biogas is usually produced at a temperature of tropical or subtropical. It is known, that the temperature of the plateau region (Mount Everest) including in the cold-temperature and possible formation of biogas from anaerobic bacteria is very small.
In General, typical analysis for digester anaerobic is divided into four ranges of temperature, i.e., thermophilic (45-60 oC), mesophilic (30-40 oC), psychrotrophic (20-30 oC), and psychrophilic (20 oC <) . Temperature conditions in the Highlands region, especially during the winter season including in the category of psychrophilic and psychrotrophic. These conditions cause low methane gas generated .
Experiment on methane gas in low temperature is performed on animal waste (beef and pork). Methane gas production in psychrophilic and psychrotrophic temperature ranges are produced from animal waste (pigs and cows) have significant differences, i.e., 73.0% of fertilizer 60.3% of pig and cow dung manure .

Biogas Project Is Mt. Everest
Biogas project is Mt. Everest starting in 2010. The resulting design and innovation has been done gives a very meaningful to impact the economy of around Mount Everest. Initiator of the project is Garry Porter. He decided to take part in Biogas project is Mt. Everest.
In General, the term typical analysis for digester biogas is nothing new in the world of technology, especially in renewable energy. In this project, biogas technology by utilizing biogas typical analysis for digester has a role as a supplier of electricity in the resting place of the climbers. Objects used in this project is human waste (feces) and also junk-garbage in Mount Everest.
Mount Everest has a temperature below zero degrees centigrade, it is certain none of the bacteria that can live in this place. Typical analysis for digester biogas use in this project is not an easy thing, this is due to anaerobic bacteria bakter-Shaper biogas can only be active in warm temperatures. Previously, a typical analysis for digester (gastrointestinal drugs) have been used in some countries, such as Nepal, China, and India. The solution given to the bacteria-bacterial mengahangatkan is the use of the arrangement (array) 8.5 kW solar cell connected on two 48 Volt battery so that bacteria stay awake in warm temperature all night long. This is due to the time it takes in the mengahasilkan gas metananya is 24 hours.
Garry Potter and his team are optimistic that the project will succeed. He hoped the existence of this project, then the environment around Mount Everest remains awake and able to be enjoyed by generations to come .
