MARRERO-DIAZ, Yoell; CRUZ-ESTOPINAN, Elisa Beatriz  e  SUAREZ-BENITEZ, Miguel. Atmospheric pollutants from sugar mills from Holguín, Cuba: A local public management tool. Rev. Cubana Met. [online]. 2020, vol.26, n.2  Epub 01-Jun-2020. ISSN 2664-0880.

The high emissions of pollutants into the atmosphere are the cause of various environmental problems today, from the local level, to the global scale. For its evaluation, the study estimated Sulfur Dioxide (SO2), Nitrogen Oxides (NOX), and Particulate Material smaller than 10 and 2.5 micrometers (PM10 and PM2.5), emitted by steam generators of sugar mills from the province of Holguin. The calculation method based on the emission factor was used to determine the emission rate of these pollutants. As a fundamental result it was obtained that the steam generators of the sugar mills evaluated emit mainly PM10 (10 675,835 t / year), PM2.5 (5 330,389 t / year), and NOX (903,456 t / year) and to a lesser extent SO2 (376,440 t / year); emission values ​​that exceed those of conventional steam generators that use hydrocarbons as fuel, but lower than those of thermoelectric and generator sets. The comparison of the maximum permissible emissions with respect to NC / TS 803: 2010, for the category of existing sources, showed that the values ​​established for the PM10 and PM2.5 of all chimneys are exceeded and in the case of NOX only the López Peña and Cristino Naranjo plants exceed the standard, for SO2 none of the emissions exceeds the maximum set value.
