8.6 Degassing systemTrial gas pumpings were performed in order to design the landfill degassing system (Fig. 26). Theperformed tests gave the content of biogas. The main components of biogas are: methane (ca.60%), carbon dioxide (ca. 35%), oxide (ca.3%), carbon monoxide, sulphured hydrogen andammonia. The tests proved that the main biogas production would take place in the next 20 years.According to this prediction, its volume will amount to 1- 6 mln m 3 per year.The degassing system consists of:- 80 biogas drilled wells (Fig. 27),- 2 gas collection containers (Fig. 28),- 10 km gas pipe collector to the Góra Kalwaria town,- electricity aggregate unit.At present, 58 biogas wells are linked to the system. The remaining wells will be drilled in the nextyear.FIG. 26 Trial gas pumping on the landfillFIG. 27 Construction of gas well on the landfillFIG. 28 Biogas collection container and the top cover of the biogas well21
