The process of creation and analysis of the landfill gas from the landfill in the region of Pchinja

Abstract

In this paper the processes that take place in the dumps and methods of formation of the landfill gas were first theoretically analysed, and then on the specific cases. The proper management of the landfill gas is examined. The potential treatment of the landfill gas is shown through the scheme, and it provides an overview of how the landfill gas can be used for combined heat and power generation. The results of measurements of the concentration and composition of the landfill gas in the Pchinja region are presented, as well as on the landfills in Vranje, Bujanovac, Trgovishte, Bosilegrad and Vladicin Han. The systematic monitoring pointed to an inadequate placement and the insufficient number of biothorns. The conclusion is that the minimal measures of protection from an explosion and fire are not done correctly. Further researches should be directed toward preventing the release of hazardous gases from the landfill body into the atmosphere. It is necessary to find positive solutions for the re-use of the landfill gas as a renewable energy source. The aim is to move from passive to active extraction systems.
