For the environment:

Radioactivity control
In our plant we perform the RADIOMETRIC monitoring on all incoming and outgoing vehicles.

In our plant we installed a rainwater treatment and purification system, for both run-off and first rain, in accordance with the law.

Alternative energy
Our company contributes to the environmental protection, using exclusively energy produced by renewable sources, to the benefit of the environment and the community.

Solar Panels
We installed solar panels to produce sanitary water and reduce the consumption of LPG, substituting it with the use of a renewable energy.

Energy Savings
An outdoor reflecting solar control film has been applied to the glazed surfaces, up to reduce the effect of the sunrays of about five degrees. These films also have the function of isolating during the winter season, keeping the heat inside our offices stable.

The technical office of the plant constantly implements a series of interventions aimed at energy efficiency which can basically be divided into:

  • installation of advanced technological systems to perform the operations of the various manufacturing processes with the use, among other things, of high energy efficiency inventer motors;
  • use of low energy consumption lighting devices. Since 2018, a relamping of the ordinary lighting system of the external areas and subsequently of the internal ones has been carried out with devices equipped with a LED light source (light Emitting Diode, i.e. light emitting diodes).
