Waste management

Waste production and management

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

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

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.

Waste typeProduction Sites - Total waste production decreased due to the reduction of non-hazardous waste, mainly at the US Batesburg and the Italian Tito Scalo sites. Furthermore, the proportion of recovered waste increased compared to the disposed waste.

Office sites - The total quantity of waste produced, particularly non-hazardous waste, increased in 2016. The strong growth is related to the Australian Brisbane and Perth sites. On the other hand, the proportion of disposed waste increased compared to the recovered waste. 

The abovementioned trends are reflected by the Kilograms of waste produced per hour worked indicator, which strongly decreased at production sites (due to the increased number of hours worked) while the office sites saw a strong growth of the indicator, due to the combined effect of the reduction of hours worked, and the increase of waste production.

Packaging, domestic urban waste and metal waste

Ansaldo STS uses various mixes of packaging: plastic, cardboard and wood (crates). Part of the plastic, cardboard and wood packaging is reused to package similar products as Ansaldo STS introduced a specific policy for this, especially for the central warehouses at the Piossasco and Tito Scalo sites.

All cardboard and mixed material packaging are completely recovered as waste.

Paper Packaging 69.63 0% 100%
Wood Packaging 32.18 12% 88%
Plastic Packaging 0.3 5% 95%
Mixed Material Packaging 9.8 3% 97%

A reduction in the production of this typology of waste was registered between 2014 and 2016. More specifically, tons produced per employee decreased by 11.7% compared to 2015.

Furthermore, the production of metal waste decreased compared to 2015, especially in the US Batesburg production site and in the Italian Piossasco site.

Soil remediation

In May 2012, the DHEC (Department of Health and Environmental Control) sent to Ansaldo STS, Batesburg site, the approval of the work plan developed by a specialized consulting firm, which set out a proposal for the characterization of soil and groundwater closed to the factory. The Work approved plan anticipated:

  • the installation of 8 permanent wells for sampling;
  • a soil and subsoil sampling campaign in the perimeter area to the plant Ansaldo STS;
  • gas - surveys in groundwater to check the concentration of VOCs in the production of the plant.

In December 2014 was signed the Voluntary Clean Up, a contract between the SCDHEC (South Carolina Department of Health and Environmental Control) and Ansaldo STS USA in which Ansaldo STS is committed to implementing the activities (such as the drafting of the Focused Feasibility Study, the Long Term Groundwater Monitoring Plan, the Health and Safety Plan and the Written progress report) aimed at continuous improvement and constant coordination with the SCDHEC, considering all the possible remedies that can be implemented in relation to cost and impacts on environment, health and regular work activities.

ERM (Environmental Resources Management), on behalf of Ansaldo STS USA, has provided the presentation of the SBB (Focused Feasibility Plan, in accordance with the Voluntary Cleanup, regulations and guidelines in the environmental field). In the document, after a detailed background of remediation activities previously carried out, an analysis is made of the possible alternatives and the criteria according to which it will opt for the most suitable choice Environmental performance | The Environment, Health and Safety (Overall protection of human health and the environment, long term effectiveness and performance, short term effectiveness, compliance with regulatory requirements, reduction of toxicity, mobility or volume, possible implementations, cost, state acceptance). The FFS was presented to SCDHEC and a first meeting was made on 31 March 2015. Additional sampling for detailing the nature of the contaminants in both surface water and sediments have been requested and regularly carried out (late 2015 and early 2016). The FFS has therefore been revised with all the data from the monitoring required and evaluating the alternatives that can be implemented on the basis of a cost-benefit analysis. The FFS has been submitted to SCDHEC in December 2016. It will be up to SCDHEC the final decision on the plan to implement.


There are two Ansaldo STS sites in proximity of protected areas:

  • Les Ulis (France) – total area 20,000 m2 (40% offices, 30% streets and parking lots, 30% green areas) where administrative and sales activities, as well as tests on electronic systems are carried out. The site is certified ISO 14001 and is close to the Bois of the Gellesche20, with an area of 16 hectares.
  • Tito Scalo (Pz) – total area 40,000 m2 (21% plants, warehouses and offices, 19% streets and parking lots, 60% green areas) where activities of manual and automated welding, as well as painting of circuit boards, are carried out. The site is certified ISO 14001 and EMAS registered. It is at less than 3 km far from the lake of Pantano, Regional Natural Reserve and Oasis of WWF. Pantano di Pignola21 is located in a Site of Community Importance and in a Special Protection Area (SIC-ZPS IT9210142), in the municipality of Pignola (Pz). It is also RAMSAR Area (Convention on Wetlands of International Importance). Due to the insignificant activity of the site with respect to biodiversity, the only biodiversity indicator considered by the EMAS is: Number of Employees per m2 of the area.


Noise levels at all Ansaldo STS sites are observed and exterior and interior noises are monitored according to the frequencies provided for by current legislation to ensure compliance with 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 exceeded.
