To conclude, Zwentendorf benefits from well-chosen technology optimized for the best

use of waste energy at the site of operation. The energetic interplay with neighbouring industries

guarantees very high efficiency of operations, while strict emissions limits push the technology to

achieve very low levels of emissions.
