Efficient and conscious water use is one of the principal components of the Pirelli environmental strategy, which has undergone numerous improvements over the last several years. These activities have involved and still involve both the overall efficiency of production processes, from design of machinery to facility management, and the contribution which every employee can make towards reducing consumption of this precious resource.
Since 2009, the commitment made at all manufacturing sites has led to saving 14.5 million cubic metres of water. This amount is very close to the absolute volume of the annual water withdrawal by the entire Pirelli Group. This figure might be the one that best expresses the commitment of the Company to protection of water sources in the communities where it operates.
In fact, aside from the quantitative and global aspect, Pirelli dedicates great attention to the local context of water resources, aware that any water savings or improvement in discharges immediately and directly benefits the local community.
WITHDRAWAL OF WATER
In quantitative terms, there was an absolute withdrawal of 15 million cubic metres in 2013, with a reduction in the specific amount that was 10% higher than in 2012.
Notwithstanding this tangible and significant saving, following the macroeconomic conditions and new scope of reporting, the goal of reducing specific water withdrawal was redefined and transferred to 2020. As compared with 2009, the specific withdrawal will be reduced by 50% by 2017 and 58% by 2020.
Accordingly, to give a comprehensive overview of its water withdrawal, Pirelli monitors and reports on the following three indicators:
- absolute withdrawal, measured in cubic metres, which comprises the total uptake of water by the Group;
- specific withdrawal, measured in cubic metres per ton of finished product, which indicates the withdrawal of water used to make one ton of finished product;
- specific withdrawal, as measured in cubic metres per euro of Operating Income.
All the figures reported in this section have been collected by taking direct or indirect measurements, and are communicated by the local units.
The two graphs below show the weight of the water procurement per type of source and the distribution of absolute withdrawals per type of production business.
TYPE OF WATER SOURCES
DISTRIBUTION OF WATER WITHDRAWAL BY USE
More than half the water drawn is taken from wells within the plants and authorised by the delegated authorities. Furthermore, Pirelli obtains about one fourth of its requirements from surface water, while dedicating special care to guaranteeing that this volume is marginal in relation to the volume of the affected water bodies (always less than 5%). In particular, about 10% is taken from water bodies located in Brazil and protected by national laws and regulations. Finally, about 700,000 cubic metres of water used are obtained from treatment of waste water generated by its own manufacturing processes.
A total of about 10 million cubic metres of water were discharged, with about 70% of this into surface water bodies, but always in quantities that are marginal in relation to the volume of the capture basis (always less than 5%) and without significantly impacting biodiversity.
The remaining amount was discharged into sewer networks. Before being discharged into the final recipient, industrial waste water – adequately treated as necessary – is periodically subjected to analytical tests that certify compliance with locally applicable statutory limits. Specifically in regard to the quality of industrial discharges at the Tyre sites, indicative values of the total average are: 8 mg/l of BOD5 (Biochemical Oxygen Demand), 41 mg/l of COD (Chemical Oxygen Demand) and 23 mg/l of Total Suspended Solids.
