LANDFILL GAS EXTRACTION SYSTEMS AND UTILISATION IN HUNGARY PUSZTAZAMOR LANDFILL SITE OF FKF ZRT. BUDAPEST

The Pusztazámor landfill is the largest Hungarian domestic waste landfill site

which was built in 2000, employing state-of-the-art technology. The placement of domestic

waste started in 2000 and will, in all probability, continue until 2005. In the first of three

placement segments, a gas extraction system with a gas booster station and a flare system was

started-up in autumn 2006 in one section to be able to design the final gas utilisation plant with

regard to the gas quantity and quality. After a test operation (pumping trail) of only 6 months, it

turned out that the gas quality is suitable for the utilisation in a gas engine, even in accordance

with the strict TA air 2002 requirements. However, the usual West-European gas prognosis

models cannot fully be applied to Hungary. The conservative designs and calculations regarding

the amount of gas will probably be exceeded by a factor of “1.5 to 2”. Reasons for this could be

the mild climate and higher water introductions into the landfill body. The effect on the

chronological course of the gas production remains to be seen
