2.6 Base materials / Ancillary materials
Coated particleboard bonded with UF/MUF consist of
(dimensions as % by mass):
Wood chips, approx. 85%
Water, approx. 47%
UF glue / MUF glue (urea resin, melamine
urea resin), approx. 810%
Paraffin wax emulsion, <1.5%
Coated particleboard bonded with PMDI consist of
(dimensions as % by mass):
Wood chips, approx. 85%
Water, approx. 47%
PMDI glue, approx. 810%
Paraffin wax emulsion, <1.5%
Wood from indigenous, largely regional forest
plantations is used for manufacturing particleboard.
This wood is typically procured from forests within a
radius of up to 250 km of the plants’ locations
(maximum distances for wood procurement in extreme
cases can reach 600 to 850 km, depending on the
site).
Furthermore, sawmill residues and recycled wood are
also used as key raw materials in the production of
particleboard.
The entire particleboard range can be made available
on request as FSC
®
certified or PEFC™ certified
products.
Additionally, all range includes CE marked products.
2.7 Manufacture
The wood is chipped, screened and dried. Surface
layer and core layer materials are then glued and
scattered on a forming belt as a particles’ mat. This is
pressed into panels under high pressure in a hot press.
The panels are trimmed, picked and sanded on both
sides after cooling.
Finaly the panels are coated with melamine
impregnated paper in a shortcycle press.
All leftovers incurred during board manufacture are
redirected into the process or used as fuel to supply
the energy needs of the manufacturing process on site.
A process diagram is presented below.
The production sites are certified according to the
following standards:
/ISO 9001:2008/;
/ISO 14001:2009/;
/OHSAS 18001:2007/;
/EN ISO 50001:2011/ (German and
Portuguese sites).
2.8 Environment and health during
manufacturing
Health protection: Due to the manufacturing
conditions, no special health protection measures over
and beyond the regulatory guidelines are required. The
reference occupational exposure limit values are
complied with.
Emissions into air: Waste air generated during
production is cleaned in accordance with regulatory
requirements. Emissions have to comply with the
values specified by the operation licenses of the
different sites, specified according to national laws.
Emissions into water/soil: No normal process
contamination of water or soil exists. Typically, the
production process of particleboard does not have any
productionrelated waste water.
Noise: Noise surveys are required and are performed
for each site according to respective national
regulations. Noiseintensive plant areas such as
chipping are encapsulated or protected appropriately
by structural measures.
