Visiting Gdansk Recycling

Together with the partners of the #LiquidEnergy project, we were today at Zakład Utylizacyjny w Gdańsku in Miasto Gdańsk. We watched the degassing system of a landfill. Our experts check how biogas recovered from waste can be used.

How is methane used from waste stored at the Waste Treatment Utility in Gdańsk? How does the degassing system work? How much gas can be obtained this way? This is what the partners of the Liquid Energy project found out during a site visit on May 17 as part of a study project visit.

At the request of the Metropolitan Area Gdańsk-Gdynia-Sopot , one of the partners of the Liquid Energy project, experts are conducting an analysis for Waste Treatment Utility in Gdańsk. Its aim is to investigate the possibility of using liquefied gas (LNG) and biogas (bioLNG) as a source of waste for fuel production.

During the visit to the Waste Treatment Utility in Gdańsk, the partners of the Liquid Energy project saw the degassing system of the landfill. President Grzegorz Orzeszko talked about the operation of this complicated system.

– We have over 300 wells that are connected to 13 collection stations – said the president. – The stations are connected by collectors to one suction pipe. This is one great system of communicating vessels. Changing the parameters of one part requires adjusting the others. This system is installed on an area of over 20 hectares. It’s miles of pipeline. The amount of gas produced is variable, depending on the “life” stage of a given landfill quarters. Metagenic processes change depending on the waste storage period. At the moment, we are able to recover a maximum of 700-800 cubic meters per hour of gas with a methane content of 55 percent.

The plans of the fuel companies related to the development of LNG infrastructure indicate that there is a future ahead of this fuel. The president of Waste Treatment Utility has no doubts about it.

– There are more and more LNG refueling stations, more and more trucks are powered by LNG- said Grzegorz Orzeszko. – This shows that despite the lack of dedicated support for LNG, the market is striving to develop this energy carrier, which is in many cases a cheaper solution than conventional fuels.
