Atmospheric emissions
Our environmental mission began in the early ’70's when we made our first investment on an arm-filter for the aspiration and collecting of EAF dust, which substituted the old water-based system. In the years ’85-’86 with the installation of the ‘dog-house’ (sic) (a type of box for the insulation of the EAF) and an aspiration system, dust collection was fully operational and effective.
The majority of the investment was made during the years ’92-’94 when the new filter plant was installed in addition to the ‘elephant-house’ (sic) (a box that encloses all of the EAF area). For this project half of the investment of that triennium was spent. With following additional implementations we obtained an increase in the efficiency of the filter plant, particularly after the installation of the continuous scrap charge (Consteel) that reduces secondary emissions.
Following a long period environmental policy, in the next two years 2009-10 we are revamping the filter system, to reduce its energetic consumption and its acoustic impact.
