Waste production and management

The production of waste is an environmental aspect that is assessed and measured at all Ansaldo STS sites and work sites and when the environmental aspects of work sites and the construction of civil and technological works are analysed.

All Ansaldo STS sites have waste collection areas depending on the type of waste and site layout.

In 2013, there was a sharp decrease in the total kg of waste produced by office sites and the kg produced per hour worked.

Hazardous materials

There are no hazardous materials pursuant to Legislative decree no. 344/99 and subsequent modifications and integrations at Ansaldo STS’ sites. Substances harmful to the ozone layer are present at the Piossasco site (0.13 tonnes) and the Batesburg site (0.09 tonnes).The Riom production site also has hazardous materials (0.15 tonnes) and raw materials (0.05t) classified as R50 (highly toxic for water organisms), substances (0.01t) and raw materials (0.05t) classified as R51 (toxic for water organisms) and substances (0.16t) and raw materials (0.05t) classified as R53 (can provoke long-term negative effects on water habitats).


In May 2012, the DHEC (Department of Health and Environmental Control) sent Ansaldo STS, at the Batesburg site, its approval for the work plan proposed by ERM, an advisory company it had contacted for this purpose, and which had presented a proposal for the treatment of the soil and underground water near the site area. The approved work plan provides for:

  • the installation of eight permanent wells for the drawing of samples;
  • a soil and underground sampling campaign in the area surrounding the Ansaldo STS site;
  • surveying with gas in the underground water to check the concentration of VOC in the site’s production area.

The plan began being implemented in 2013.


Noise levels at all Ansaldo STS sites are always low and exterior and interior noise is monitored at the frequencies provided for by current legislation to monitor compliance with the applicable thresholds. When Ansaldo STS is the main contractor, during coordination and security activities, it can ask subcontractors for updates on the performance of measurements to monitor that the thresholds are not violated.

Non-conformances and environmental complaints

In 2013, there were 16 environmental incidents at Ansaldo STS, without any damage or injuries and there was no involvement of hazardous materials, one at the Les Ulis site (water leak repaired the same day), two at the Riom production site (loss of 340 cubic metres of water and loss of 2 Kg of air conditioning gas) and 13 at the Karratha site (mainly small plumbing issues and small leaks of oil or diesel).

There were two near misses at Karratha as well.

There were no environmental complaints from outside the company. There were no violations of environmental standards detected by external control bodies and there were no environmentally critical system faults.

In 2013, Ansaldo STS performed 20 in house environmental audits (four at the three production sites and 16 at office sites), 16 external environmental audits (six at the three production sites and 10 at office sites).
