10 Recycling and disposal
The product development of all Vaillant products takes
into account later recycling and/or the secure scrapping
of each component used. Vaillant factory standards
stipulate strict requirements in this regard. The selection
process for choosing the raw materials takes into
account their recycling properties , the dismantlability
and the separation facility of the component groups. We
also take into account the environmental and health
dangers associated with the recycling and disposal of
non-reusable remnants.
10.1 Unit
The Vaillant ecoTEC consists to a large extent (up to
92 %) of metallic components designed for recycling by
melting down in the steelworks. This gives these parts
almost indefinite reusability. All plastic materials are
marked properly which makes the separation and
sorting more easy when the component group needs to
be recycled.
10.2 Packaging
Vaillant strives to keep the scope of the transport
packaging for its units to an absolute minimum. When
selecting the packaging material its subsequent
reusability is taken into account. High quality cardboard
has been, for many years, a valuable raw material for
the paper and cardboard industry. The EPS components
(Styropor®) are used for protecting the unit during
transport. EPS is 100 % recyclable and CFC-free. The foil
packaging and securing straps are made from recyclable
plastic.
