Management of waste and effl uents

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

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

The most prominent waste in production sites relates to paper, cardboard and wood packaging, metal and out-of-order equipment.

Production sites - In 2017, overall production of waste fell due to the reduction in non-hazardous waste. Furthermore, the proportion of recovered waste increased compared to disposed waste.

Offices - In 2017 the total quantity of waste produced fell considerably, particularly in terms of non-hazardous waste which in 2016 was concentrated in the Australian sites in Brisbane and Perth. Furthermore, the proportion of recovered waste increased compared to disposed waste.



The trends described above are also reflected by the index of kilograms of waste produced per hour worked, which fell by 48.0% compared to 2016 due to the effect of the constant reduction in non-hazardous waste at sites and the increase in hours worked.

Packaging: waste and recycling

In terms of packaging, Ansaldo STS uses mixed material packaging, plastic, cardboard and wood (crates). As a result of a specific policy introduced by Ansaldo STS, part of the wood and plastic packaging is reused to package similar products, especially at the central warehouses at the Piossasco and Tito Scalo sites.

Waste water

The waste water produced at the sites can be classified on the basis of its use upstream from disposal, as domestic (or similar) and industrial.

All Ansaldo STS sites produce waste water that can be exclusively classified as domestic or similar, except for the Tito site. All the domestic or similar waste water is discharged into the sewers. The Naples site uses an organic wastewater treatment system.

The sites use authorised disposal points. The Batesburg and the Tito Scalo sites’ disposal points are monitored.
