Diffuse PM10 emission factors associated with dust abatement technologies in the ceramic industry

In this paper, an analytical methodology is proposed for estimating diffuse dust emissions from bulk solids managing (storage, handling, and transport) activities in the ceramic industry. The methodology is based on analytical methods drawn from the AP-42, US Environmental Protection Agency reports and the Emission Estimation Technique (EET) Manual for Mining from Environment Australia. The analytical methods were evaluated by means of experimental campaigns in open and closed bulk solids storage and managing facilities in ceramic plants.Dust concentrations and meteorological variables were recorded in experimental field studies in order to implement the experimental models: a method based on Reverse Dispersion Modelling (RDM) was applied in open facilities, and the Roof Monitor Method (RMM) was used to estimate diffuse dust emissions in closed facilities.The proposed methodology was applied to 13 ceramic plants with different technological scenarios. The methodology enabled the diffuse PM10 emission factors associated with different dust abatement technologies to be determined. This methodology thus allows the Best Available Techniques (BATs) to be selected for reducing these emissions in ceramic and similar facilities.

► In this study we evaluate and apply a methodology for estimating diffuse dust emissions from bulk solids managing areas.
► The methodology was applied to 13 facilities with different technological scenarios.
► We quantify the overall abatement efficiencies and PM10 emissions factors.
► It shows that if the appropriate measures are applied, high efficiencies can be achieved.
► It allows selection of the Best Available Techniques for reducing diffuse dust emissions.
