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.

Ansaldo STS’ policy is to reinforce prevention and the re-use, recycling and recovery of waste. All its sites have waste collection areas depending on the type of waste and site layout. Specialist companies collect and process the hazardous and non-hazardous waste.

In 2014, 5.3 tonnes of the 166 tonnes of waste disposal, which made up roughly 30% of total waste, was sent to incinerators (about 3%).

In 2014, there was an increase in the waste produced both by the production sites and office sites. The percentage of recovered waste increased compared to that disposed of by the production sites while it decreased at the office sites.

The percentage of recycled domestic and urban waste increased at the office sites and production sites.

Packaging

Ansaldo STS uses various mixes of packaging: plastic, cardboard and wood (crates).
There was a reduction in the quantities of packaging produced again in 2014 (-17%).

The 10.4 tonnes of mixed material packaging produced in 2014 were all recycled. Part of the plastic, cardboard and wood packaging was reused to pack similar products as Ansaldo STS has introduced a specific policy for this, especially for the central warehouses at the Piossasco and Tito Scalo sites.

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). In 2014, the Riom production site used 12.9 tonnes of raw materials classified as R40 (possible irreversible effects), 0.07 tonnes of raw materials classified as R50 (highly toxic for water organisms), 0.07 tonnes of raw materials classified as R51 (toxic for water organisms), 0.01 tonnes of raw materials classified as R52 (harmful to water organisms) and 0.14 tonnes of raw materials classified as R53 (can provoke long-term negative effects on water habitats).

The Les Ulis office site and the Batesburg production site have materials containing asbestos (tiles and old pipelines for steam and water, respectively). Their state of conservation was checked at the Batesburg production site in 2014.

Reclamation

In May 2012, the DHEC (Department of Health and Environmental Control) sent Ansaldo STS, at the Batesburg site, its approval for the work plan prepared by a specialist advisory company it had contacted for this purpose, and which had put together 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.

Implementation of the plan began in 2014.

Noise

Noise levels at all Ansaldo STS sites are observed 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 check that the thresholds are not violated.
