The project started on date 12.01.2015. The works have been planned to be completed in 730 days. As of April 2015, earthworks and insulation works coverage have been continuing intensively.
The scope of the project is: the rehabilitation of the site with an approximate area of 500.000 m² at the Boyuk Shore lake coast in the capital city of Baku which has been used as an uncontrolled storage site since 1960\’s and the construction of a new sanitary storage site with a storage capacity of 10 million m³ on the rehabilitated waste mass. The inside of the lake and the coast will be cleaned within the scope of the project. On the other hand, a contemporary facility enabling an Integrated Solid Waste Management, with a seepage water treatment plant (Reverse Osmosis System), facility to produce energy out of landfill gas (co-generation technique) and with similar facilities will be contributed to the country.

The Balakhani landfill project is situated on the north-eastern northern-east shore of Boyuk Shor lake of Sabunchu region in Baku area, Absheron Peninsula. The Balakhani landfill has been operating uncontrolled since 1963 until 2009 when its operation was taken over by the company Tamiz Shahar (TS) a joint stock solid waste management company which is owned by the state. and controlled by a supervisory board and functioning under the auspices of the Ministry of Economic Development.
Characteristics of the Balakhani landfill site:

  • The Balakhani landfill has been operating uncont rolled since 1963. Until today no precise records of waste amounts are available. When TS took over the site management they started to register incoming waste volumes based on truck nominal volumes. In the future a modern weight bridge system will be installed.
  • The total landfill area is around 120 ha. The total area available for waste will be around 55 ha.
  • It is estimated that the total amount of waste disposeddumped on the landfill during 2005-2012 is around 1,789,065 tons.
  • It is estimated that the total amount of waste dumped on the landfill during 2013-2024 (after rehabilitation) will be around 6,462,475 tons.
    There is currently no LFG collection and treatment system at the site. LFG is at present emitted to the atmosphere. The baseline scenario is the same as the scenario existing prior to the start of implementation of the project.

Today four waste zones (I) – (IV) are defined. Zone (I) contains the waste deposited before 1990, zone (II) contains waste deposited 1990-2004, and zone (III) contains waste deposited since 2005 until today. Zone (IV) does not yet contain any waste but is occupied with power lines which first need to be removed before future waste depositing is possible.

It is planned to first rehabilitate the existing waste zones (I) – (III) of the current landfill in order to be able to expand them afterwards vertically to use them for future waste. The rehabilitation works will consist amongst others in compacting the existing waste and dividing the area into a cell structure. In addition a LFG collection network will be constructed which will cover this whole rehabilitated area. The rehabilitated area (I) – (III) will have a final closure cover system which will serve as bottom lining system for the future vertical expansion. This area will form sector B of the future sanitary landfill. Independently of this landfill rehabilitation some preparation works will take place in the current empty zone (IV) to become afterwards also part of the future sanitary landfill (sector A). After rehabilitation, incoming waste will be first disposed in sector A and then, successively in sector B on top of the historical waste. In parallel further construction of a LFG collection network will take place to cover also the waste disposed at the new sanitary landfill
