they also use scrap as raw material, but they have not been subject to the
same requirements to analyse emissions of heavy metals to air.

The steelwork was closed in the beginning of 2002 and re-opened at the end
of 2004. The electro steelwork has been closed again from 2006; whereas
manufacturing of steel sheets at the rolling mill has continued separated
from the electro steelwork. Melting of secondary aluminium was stopped in
the end of 2008.

The emission of heavy metals and TSP from the production of steel bars and
sheets from steel scrap are based on measurements from the company Stålvalseværket
(Stålvalseværket, 2002). PM10 and PM2.5 are estimated from the
distribution between TSP, PM10 and PM2.5 from CEPMEIP (2003). The distribution
of metals for 1995/96 (Illerup et al., 1999) is used in estimation of the
different metals for the following years. The activity has varied between approximately
600 000 and 800 000 tonnes from 1990 to 2001. The production
ceased in the beginning of 2002 and restarted at the end of 2004 with regard
to melting of steel scrap in the electric arc furnace. The production of steel
bars at the steelwork is assumed to be 1/3 of the production in 2001; the
steelwork has been closed from end of 2005/beginning of 2006.
The emission of heavy metals from iron foundries is based on standard
emission factors and yearly production statistics from The Association of
