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 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.
|PRODUCTION SITES||OFFICE SITES|
|% disposed of||76%||78%||71%||3%||2%||72%|
|% disposed of||24%||4%||67%||43%||53%||45%|
|TOTAL WASTE (t)||81.48||116.69||310.62||408.91||442.89||321.16|
|% disposed of||29%||13%||67%||42%||50%||46%|
Production sites – Total waste production increased in 2015 due to the growth in non-hazardous waste, mainly at the US Batesburg site. As all waste was disposed of, a spike in the amount of disposed waste compared to recovered waste occurred. On the other hand, the proportion of hazardous waste compared to recovered waste is in line with 2014, with an increase recorded in the amount recovered.
Office sites – The total quantity of hazardous and non-hazardous waste produced decreased in 2015. The percentage of hazardous waste that was disposed of grew due to the hazardous waste produced for the first time at the site in Noida (India), which was completely disposed of. On the other hand, the recovered amount of nonhazardous waste increased.
Kilograms of waste produced per hour worked grew at the production sites due to the aforementioned increase in non-hazardous waste at the Batesburg site (despite the rise in the number of hours worked) while the sites saw an overall decrease in total waste produced, with a the decrease in hours worked.
Domestic urban waste produced and recycled
|Total domestic/urban waste (t)||490.96||606.57||571.80|
|Total recycled paper [t]||138.44||151.03||109.74|
|Total recycled plastic [t]||0.03||5.87||5.33|
|Total recycled wood [t]||36.29||33.73||17.95|
|Total recycled metal [t]||88.09||77.30||80.33|
|Total recycled glass [t]||0.01||0.15||0.11|
|Other recycled domestic/urban waste [t]||12.92||111.61||172.84|
|Total recycled waste (t)||275.77||379.69||386.29|
Ansaldo STS uses various mixes of packaging: plastic, cardboard and wood (crates).
|Quantities of mixed packaging [t]||12.56||10.42||10.60|
All packagings in mixed materials are completely recycled. Part of the plastic, cardboard and wood packagings was reused to package similar products as Ansaldo STS has introduced a specific policy for this, especially for the central warehouses at the Piossasco and Tito Scalo sites.
|Packaging material||% of material that is reused||% of material that is recovered as waste||% of material for other use|
There are no hazardous materials pursuant to Legislative decree no. 344/99 and subsequent modifications and integrations at Ansaldo STS’s sites.
Substances harmful to the ozone layer are present at the Piossasco site (0.13 tonnes) and the Batesburg site (0.09 tonnes). In 2015, the Riom production site used 4.14 tonnes of raw materials classified as R40 (possible irreversible effects), 0.07 tonnes of raw materials classified as R50 (highly toxic for water organisms), 0.01 tonnes of raw materials classified as R51 (toxic for water organisms), 0.07 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 compact asbestos (roofs and old pipes for steam and water, respectively). Their state of conservation was checked at the Batesburg production site in 2014.
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 sampling campaign and subsoil 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 Written progress reports) aimed at continuous improvement and constant coordination with the SCDHEC, considering all the possible remedies that can be implemented in a cost relationships 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 (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 March 31, 2015. Additional sampling for detailing the nature of the contaminants in both surface water sediments have been requested and regularly carried out (late 2015 and early 2016). The SBB has therefore been revised with all the data required for monitoring and evaluating the alternatives that can be implemented on a cost-benefit analysis and submissive attention of SCDHEC June 2016. It will be up to SCDHEC the final decision on the plan to implement.
