The cleanest incinerator
The aim of the research project “Landmonitoring” was to point out the effects of the new Bolzano incinerator on the environment.The Municipal Council and Ecocenter, which commissioned the study, commissioned the Department of Environmental Physics of the University of Trento, the pharmacological research institute Mario Negri in Milan and the eco-research laboratory in Bolzano to conduce out the study. Subsequently, the prestigious National Center for Atmospheric Research of Colorado (USA) and Cisam, a company specializing in environmental measurements, participated also to the research project. In addition to the weather data of the province, experts installed a sodar (vertical profiling) on the roof of the waste incinerator plant and a lidar on the roof of the country house 12 in Bolzano to survey wind direction and intensity up to 3 km altitude. After the creation of a weather-mathematical model for the orography of the basin of Bolzano, the perfect conditions (the worst possible) were finally found on February 14, 2017 to carry out the measurements. 14 research teams were positioned at the sites with maximum fallout. These were equipped with 40 special bottles for air sampling. The air contained in the bottles was then evaluated with a high-sensitivity mass spectrometer. The result? At these locations and under these conditions, the waste incinerator has 0.08% particulate matter and 0.9% nitrogen dioxide of the total emissions measured. As Ecocenter president Stefano Fattor explained, "in the rest of the territory, the concentrations of all pollutants attributable to the incinerator are neither measurable nor quantifiable".
