ENVIRONMENTAL REPORT
Differences in gas consumption rates are due mainly to the variations of the product mix requested
by the customers, characterized by different requirements in terms of unit gas consumption for their
production.
In addition, planned plant maintenance in 2011 helped reduce the consumption as well.
The following graphic summarizes the total energy consumption rates expressed in tonne of oil
equivalent.
For electricity, 1 MWh corresponds to 0.23 toe and for gas, 1000 Nm

GAS
Gas is used for direct and indirect heating of the plastic film during preheating stages before
longitudinal and transversal stretching. It is equally necessary for the surface treatment of the film to
prepare it to the following printing phases.
