All planned measures and projects, such as new construction, renovations, and decommissioning of production facilities, are carefully analyzed with regard to their impact on the eco-system or on areas requiring particular protection. Mitigation and compensatory measures are taken when necessary.
The Linz site
voestalpine has the impact of its activities on the environment, e.g., microorganisms or fish populations, examined regularly by external partners and derives appropriate measures from the results.
Environmental remediation of the coking plant, Linz, Austria
The coking plant, which began operations in 1942 and was largely destroyed toward the end of World War II, was rebuilt and continued operations. In addition to benzene, tar was also distilled on-site as a by-product of the production of coke. The effects of war and the destruction of various parts of the coking plant resulted in massive contamination of the soil at the plant site. Since 2011, the following measures have been taken to sustainably remediate and ensure the safety of the coking plant site in Linz, taking ecological and economic aspects into consideration:
- Funnel & gate system to ensure groundwater flow
- Partial excavation of the unsaturated soil zone (hotspots), soil washing to remove contaminants, and backfilling of the site
- Soil vapor extraction in the unsaturated soil zone to remove fugitive contaminants (primarily BTEX)
- Phase separation of contaminants in the saturated soil zone (primarily tar oils and light oils)
