History of Nubarashen landfill Was created about 50 years ago.
Area is about 60ha.
Located near Yerevan.
Receives 340 tons per day(102000 t/y).
Now landfill contains about 7.5 million tons of

Слайд 2History of Nubarashen landfill
Was created about 50 years ago.
Area is about
60ha.
Located near Yerevan.
Receives 340 tons per day(102000 t/y).
Now landfill contains about 7.5 million tons of domestic waste.
Have three blocks A,B,C(A is already filled).
Слайд 3Disadvantages of Nubarashen landfill
Air pollution(waste smells bad).
Greenhouse gases(Nubarashen landfill uses flaring
but they are not able to capture all the methane so part of it goes to the atmosphere and creates greenhouse effect).
Sanitary problems(good conditions for microbes to multiply).
Слайд 4Actions of Yerevan Municipality
Municipality of Yerevan signed a contract on 10
March 2009 with the Japanese Shimizu Corporation on Nubarashen Landfill Gas Capture and Power Generation project which will contribute to reduction of greenhouse gas emissions from the landfill and improvement of environmental and sanitary conditions.
Слайд 5International experience in the sphere of waste treatment
Composting
Incineration
Vermicomposting
Gas power generators
Слайд 6Ways to develop Nubarashen landfill
1.Sorting organic and inorganic waste.
2.Building a gas
power generators.
3.Building a gas pressure station.
Слайд 7Methane formation
1. Aerobic.
2. Anaerobic.
What do we need for anaerobic methane formation?
1. No air.
2. Temperature range between 20-45 C(Mesophilic) or 49-70(Thermophilic).
3. Organic waste(most important).
These three factors exist at deep layers of Nubarashen landfill.
Слайд 8Solution
Install a GAG(gas engine generator).
Change mesophilic digestion to thermophilic.
HOW?
Слайд 9Heating system for Nubarashen landfill
Using the methane created by waste we
can increase the temperature of deep layers.
This will help us to.
1. Get more methane from the same volume of organic waste(get more electricity).
2. Accelerate decompostion process.
