Feralpi Stahl- environment measures

Far below thresholds.

It goes without saying that our steel production facilities are subject to strict monitoring. The compliance with statutory emission thresholds, in particular, is checked meticulously. To facilitate continuous observation of the arising emissions, modern computerised measuring equipment has been installed in both chimneys of our steelworks. Since October 2007, the monitoring authorities have been provided with a permanent insight into the current emission values. This, too, is based on an innovative solution - remote emission monitoring.

 

Emissions well within limits.

The tables below present the results of emission measurements taken on the dust removal systems in February 2010. The values illustrate clearly, how steel production in Riesa remains well below all statutory limit values.

 

Reliable compliance at the workplaces.

 

The conditions at our workplaces are similarly monitored at regular intervals to safeguard the health of our employees. As the table shows, we are able to comply reliably with all relevant limit values.
