Abstract: In the last
few years the production of wood panels, mainly
of MDF, PB and OSB, went worldwide through a dramatic
growth period. The rapid increasing production
capacities forced a dynamic mechanization and
automation of this industrial sector. The environmental
aspects of this development have just recently
become in the focus of public interest due to
increasing environmental requirements. In the
past different technologies to reduce environmental
impact has been developed, while due to the practical
experiences only some of them can be stated as
"state of the art". The regulations
for air emissions in Central European countries
required the conception of new treatment plant,
which established a new state of the art in the
environmental technology. For the production of
PB the wet electrostatic precipitator has been
recognised to be the most effective system in
terms of investment as well as running costs and
also in terms of environmental benefits for the
cleaning of the gas coming from direct fired dries.
For MDF factories it was possible to combine the
advantages of known technologies for waste air
and water and to develop them further firstly
to a pilot plant and later to the "state
of the art" in this field. This new system
completely closed all water cycles of the production
site and minimized the exhaust of air pollutants.
During more than five years operation this system
clearly proved its economical and technical advantages.
The development of this treatment plant prevailed
new experiences and know-how, which are very helpful
for the design and optimization of new equipment
generation for reducing the environmental impact
of the wood based panels industry.
Key words: wood based panels, PB,
MDF, OSB, waste water, waste air, environment
impact.
