Through our engagement activities, we understand that water management is important for a number of our stakeholders and we recognize the importance of using water responsibly and reducing waste.
- 2018 and 2019 Performance
In 2018, our total water consumption continued to decrease. We recorded a 10% reduction of water used per metric tonne of product since 2017. In 2019, we recorded a 1% reduction of water used per metric tonne of product since 2017, the smaller decrease this year is largely down to increased decommissioning activities and efficiency issues with plant processes during the warm summer period. We are now using 53% less water per metric tonne of product in our manufacturing process than we did in the 2006 baseline year.
- 2019 Water Saving Activities
Although none of our production facilities that use water in the process are located in water constrained areas, we ensure that we use this valuable resource as carefully and efficiently as possible. Examples of water saving activities in 2019 include:
- Salisbury, NC, US, invested in a 70,000-gallon Dissolved Air Flotation (DAF) wastewater treatment process to replace an aging gravity clarifier. The new DAF unit ensures the site maintains compliance with its discharge permits, removing solids and improving waste water quality.
- Barcelona, Spain, has implemented a leak detection program for steam and water used in the reaction cooling and heating systems. The site is also minimizing water usage by switching from water to steam cleaning and ensuring efficient pressure settings are used.
- Castiglione, Italy, introduced a water consumption monitoring program and has used the data obtained to identify a list of targeted water reduction projects to take forward in 2020.
- Leuna, Germany, made improvements to the monitoring of condensate intake and release to avoid any uncontrolled use of water.
- Oklahoma, US, is reusing all flush and cooling water onsite reducing the need for fresh water.
- A rainwater collection upgrade project at our St-Mihiel, France, site ensures rainwater is collected and reused on site by pumping it through the site’s bioplant.
- Herne, Germany, has installed steam meters to help monitor and target projects for water and energy reduction.
- Our Performance Chemicals business continues to explore opportunities to create concentrated and solid versions of surfactants to reduce the amount of water required during manufacture and use.
