Water

A serious global concern

Our approach

Since our production is based on fermentation with subsequent downstream processing, which uses a considerable amount of water for cooling and processing, this is a topic we have to and want to address. The four main water sources affected by Jungbunzlauer’s operations are the rivers Thaya in Austria, Rhine in Marckolsheim, Neckar in Germany and the Welland Canal in Canada. Water is being drawn from these rivers mainly for cooling purposes and for use in other parts of the production process. While so called non-contact cooling water is directly returned to the river in question, process water is treated first in state-of-the-art wastewater treatment plants at all our production sites before it is returned to the water source.

Each production site has a wastewater treatment plant to ensure the correct treatment of water effluents. Local regulatory requirements are fulfilled. There is a dedicated employee in each plant responsible for the treatment of wastewater. Guidelines on water handling are summarised in the Responsible Care® report of the responsible production site. In our wastewater treatment plant we utilise some waste streams in anaerobic digesters to produce biogas, which is used on site for the production of steam.

The water consumption as well as water treated in wastewater treatment plants in our production sites is measured and recorded in the annual Responsible Care® report. Each production plant and each office location manage water usage individually.

Our ambition

We aim to reduce our water consumption as much as possible. Additionally we strive to adhere to all set limits regarding our wastewater treatment. We also continuously try to improve the recycling of water streams, where feasible. Individual improvement goals regarding water are set in each production plant and progress is measured.

Examples of water reduction projects implemented in 2020 in our production sites

  • The amount of phosphate in cleaned wastewater was reduced by 50% in Ladenburg, Germany

  • By improving the cooling efficiency of the cooling towers, the water consumption was reduced in Ladenburg, Germany

  • Reduction of wastewater volumes in Marckolsheim, France

  • Improvements in cooling water collection with the installation of additional drainage in Port Colborne, Canada

  • Improved operation of the wastewater treatment process with new monitoring tools in Port Colborne, Canada

  • Water savings by redirection of water streams

Key measures and evaluation

In 2020, water recovery and usage were optimised in our production plants by implementing new processes or reconstructions. This has contributed to a reduction in water consumption. There are also processes to maximise the reuse of water in our sites.

Outlook

We will continue to monitor and record our water usage and implement measures to reduce water consumption where possible. We also strive to improve comparability of data on water use in our different production sites. In 2021, an additional state-of-the-art biogas digester for the production of biogas from waste streams will become operational.
