| Abstract | The goal of this research was to test the air emissions resulting from landfill gas combustion in a 250-kW cogeneration unit, in the context of pollutant emission due to the produced electricity. The test results mainly revealed emissions of carbon dioxide, sulfur dioxide, nitrogen oxides, carbon oxides, and dust. The volume of emissions of individual pollutants was compared with the emission values reported from the emission balancing database. The highest emission burdens concerned the production of one MWh of electricity for carbon dioxide 579.80 kgCO2 center dot MWh- 1, carbon monoxide 2.57 kgCO2 center dot MWh- 1, and nitrogen oxides 1.77 kgNOx center dot MWh- 1. It is worth noting that small cogeneration installations are not covered by emission standards and so they are not equipped with a device for reducing gaseous and particulate pollution. The tests revealed a difference between the actual emissions from the tested installation and the values reported to the national database. The innovation of this study is that it demonstrates the real emission burden of renewable energy in the context of sustainable development. The results can be used as input material for discussion to apply gaseous and particulate pollution reduction systems for cogeneration installations powered by landfill gas, including various types of biogases. |
