Study of the pollutant emissions released through the combustion of green waste

The purpose of this work is to experimentally evaluate the emissions generated by the combustion of plants and to determine how the mass of vegetation and their moisture level influence these emissions. To carry out this study, cistus tree branches were burned under a large oxygen-consumption calorimeter which was used in conjunction with a Fourier transform infrared spectrometer. This revealed that the smoke was comprised of CO2, H2O, CO, CH4, NO, NO2, NH3, SO2, and non-methane organic compounds (NMOC). By increasing the initial mass, the emission factors of NO, NO2 and CO2 increase. Increasing moisture has the effect of increasing the emission factors of CO, CH4, NH3, NMOC and aerosols, but decreasing the CO2, NO and NO2. This study demonstrated the significance of drying out green waste for as long as possible before burning it.
