ENVIRONMENTAL<br />
PROTECTION<br />
The Andritz Group is committed to promoting<br />
environmental protection and conservation of<br />
natural resources. Andritz AG’s official Declaration<br />
of Environmental Protection establishes the principles<br />
and objectives of its environmental policy.<br />
The Group also pursues a proactive information<br />
policy vis-à-vis the communities in the vicinity of<br />
the Group’s production plants, the general public,<br />
and government authorities.<br />
Andritz’s manufacturing processes and the products<br />
it makes are designed to minimize the consumption<br />
of natural resources and energy in order<br />
to have minimum impact on the environment. This<br />
approach also reduces production and operating<br />
costs to the benefit of Andritz customers.<br />
Uniform environmental protection guidelines<br />
are implemented at all Andritz production sites.<br />
Responsible managers within each Andritz facility<br />
are empowered to ensure that the guidelines are<br />
strictly adhered to.<br />
As a commitment to continuous improvement,<br />
each year Andritz AG has the results of its environmental<br />
protection activities examined by a<br />
commission appointed by the City of Graz. In<br />
<strong>2004</strong>, the Andritz site in Graz again received the<br />
“ÖKOPROFIT” certificate awarded by the City<br />
of Graz for special environmental achievements.<br />
Measures to further reduce energy consumption<br />
were continued in <strong>2004</strong>, including improved thermal<br />
insulation in the workshops and the use of<br />
power-saving lighting. Also, the portion of goods<br />
shipped by rail was considerably increased, reducing<br />
truck traffic on the surrounding roads.<br />
Andritz products for a cleaner environment<br />
The Pulp and Paper Business Area offers<br />
processes, systems, and equipment that reduce<br />
waste, save energy, and minimize the environmental<br />
impact of its customers’ operations.<br />
<strong>ANDRITZ</strong> <strong>2004</strong><br />
Most mills have taken significant actions to<br />
reduce the environmental impact if bleaching is a<br />
part of their production processes. Andritz continues<br />
to be a technology leader in the development<br />
of bleaching processes which utilize alternatives<br />
to chlorine for reduced environmental impact.<br />
Andritz systems for dewatering (such as presses<br />
and filters) and water recycling (within the fiberline<br />
or during the papermaking process) within the<br />
mill reduce the effluent loads on nearby receiving<br />
waters.<br />
In the chemical recovery area of a pulp mill,<br />
systems for black liquor evaporation, combustion,<br />
and white liquor production have a significant<br />
impact on the emissions from the mill.<br />
Andritz black liquor evaporators produce reusable<br />
process water from the black liquor. The reuse<br />
of condensate reduces the COD load in effluent<br />
waters and the amount of fresh water required in<br />
the pulping/recovery process. Condensates generated<br />
within the black liquor evaporation process<br />
are segregated and collected within the Andritz<br />
system and methanol found in the condensate<br />
is “stripped” from the condensate for further processing.<br />
Andritz also provides methanol liquefaction<br />
equipment so that the liquefied methanol can<br />
then be used to replace fossil fuel in the lime kiln.<br />
After extensive research and development work,<br />
the emissions from a state-of-the-art Andritz<br />
recovery boiler are minimal. For example, the SO2<br />
emissions approach zero when the black liquor is<br />
evaporated into high dry solids and a <strong>Vertical</strong> Air<br />
system is utilized in the recovery boiler.<br />
Maximum electricity production and minimal<br />
greenhouse gas emissions are becoming important<br />
considerations for the increasingly energy-<br />
and environmentally-conscious pulp industry. The<br />
High Energy Recovery Boiler (HERB) concept,<br />
developed by Andritz, offers an effective way to
