Water management

Regional water conditions

Gränges uses water mainly for cooling purposes, such as cooling production equipment and preventing overheating and production disruptions. The production facilities in Americas and Shanghai have closed-loop cooling systems with a high degree of water recirculation, which reduce water consumption and the risk of water contamination. In addition, water is used to make up emulsions in different process steps and for domestic purposes. Ground water is used at the site in Huntingdon whereas municipal water is used at the Salisbury, Newport and Shanghai sites. The production facility in Finspång uses surface water withdrawn from two nearby lakes. The water is primarily used for cooling purpose and is then released into local waterways. Daily measurements are made to ensure that the released water does not contain hazardous substances and water that may contain contaminants is treated by an external partner before being returned to water bodies.

Local water management plans

Gränges manages water-related aspects based on local circumstances as the company’s production sites are located in areas with various water stress and risks. Input from the World Resources Institute’s Aqueduct Water Risk Atlas shows that the sites in Finspång and Newport are located in areas with low-to medium risk, Huntingdon and Salisbury sites in medium-to-high risk, and Shanghai in a high-risk area. No water sources are considered to be significantly affected by the water withdrawal or discharge from Gränges’ operations.

As water-related aspects and risks are managed based on local circumstances, Gränges works to implement local water management plans in all its locations. These plans include local targets and activities to address water-related impacts, such as water efficiency improvements, quality of effluent discharge, conservation activities, and local stakeholder engagement. In 2020, Gränges implemented local water management plans in two sites: Finspång and Shanghai.

Gränges also includes water risks when conducting supplier sustainability assessments.

Note: All numbers exclude Gränges Konin and Gränges Powder Metallurgy.
