Слайд 1

Описание слайда:

Green Building Green City Action Plan for Yerevan “Waste”(Nubarashen landfill) Abrahamyan Henrik

Слайд 2

Описание слайда:

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 domestic waste. Have three blocks A,B,C(A is already filled).

Слайд 3

Описание слайда:

Disadvantages 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 4

Описание слайда:

Actions 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 5

Описание слайда:

International experience in the sphere of waste treatment Composting Incineration Vermicomposting Gas power generators

Слайд 6

Описание слайда:

Ways to develop Nubarashen landfill 1.Sorting organic and inorganic waste. 2.Building a gas power generators. 3.Building a gas pressure station.

Слайд 7

Описание слайда:

Methane 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 8

Описание слайда:

Solution Install a GAG(gas engine generator). Change mesophilic digestion to thermophilic. HOW?

Слайд 9

Описание слайда:

Heating 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.
