5.1 Air emissions
Air emissions produced by Taghleef Industries S.p.A. manufacturing plant derive mainly from the
extrusion, stretching and film surface treatment stages.
The polluting substances emitted by the 64 emission points and regularly authorized by the
competent regional bodies are:
•
total dust
•
ozone
•
formaldehyde
•
mineral oils (such as fumes or fog)
In addition there are the classic emissions that characterize the heating system and are periodically
checked as per the regulations in force.
In order to respect the limits defined by law, emissions are managed using specific abatement plants,
depending on the type of pollutants detected in the various flows. On the other hand, formaldehyde
emissions are not subject to the abatement process because their rates are far below the law limit.
The air emission treatment plants are related to:
•
dust abatement using cyclone and bag filters
•
ozone abatement using activated carbon scrubbers
•
oils abatement using coalescing filters
Below there is a list of average rates registered for each pollutant during the four-year period with
respect to the authorized limit of emissions. As a precautionary measure, when the level of pollutant
was below the limit of analytical detectability, it was considered to be equal to the limit itself.
