Energy 

Getliņi ecological landfill is one of the largest and most modern producers of green energy in Latvia.
The source of energy is the landfill gas – natural gas which mainly consists of methane. It is formed in covered waste deposits – biodegradation cells, in which unrecyclable waste is stored and which have anaerobic environment, i.e., an environment protected from exposure to air or rainwater.

 

Gas

The landfill gas that is formed in the waste biodegradation cells is collected through perforated pipes placed in the waste biodegradation cells which are located at every 7-meter-thick layer of waste.
When the gas is pumped out of a biodegradation cell, it is delivered to automatic gas control stations where it is tested, purified of H2S, Cl, F, siloxanes and volatile organic compounds (VOC), and then transferred to the Getliņi power unit. In the power unit, the gas is incinerated in six internal combustion engines (JGS 320 gas engines produced by GE Jenbacher) and is transformed into energy: electricity and heat.
The energy is produced in the following proportions: 40% electricity and 46% heat.
It is worth mentioning that trained technical personnel are responsible for the gas production and operations of the power unit. Gas experts from the Energy Department design and assemble the gas production systems, as well as regulate all of them, including the automatic gas control stations, and oversee their operations.

 

 

Electricity

The energy is produced in the following proportions: 40% electricity and 46% heat.
SIA Getliņi EKO annually produces about 35 GWh of electricity and sells most of these to AS Latvenergo.
In recent years, calculations of energy produced have been made in terms of pure methane (CH4): 7,844,760 m3, corresponding to 78,011,000 kWh of energy. 

 

 

Heat

The energy is produced in the following proportions: 40% electricity and 46% heat.
SIA Getliņi EKO annually produces about 20,000 MWh of heat.
SIA Getliņi EKO produces heat as a by-product, by cooling the combustion engines and exhaust gases produced when burning the landfill gas.
Heat is used in the company’s economic operations: heating of greenhouses, heating the work space, hot water production, heating the water purification equipment reactor, heating the infiltrate collection and recirculation.
