Estimation of Industrial Emissions during Pyrolysis and Combustion of Different Wastes Using Laboratory Data

Abstract In our lab, we have been studying the emissions of different pollutants during pyrolysis and combustion of wastes under different conditions for the last three decades. These studies have focused on the effect of temperature and presence of oxygen on the production of different pollutants....
