Environment/disposal

Environmental protection is a key commitment of the Bosch Group.
Quality of products, efficiency and environmental protection are equally
important objectives for us. All legislation pertaining to the
environmental protection is strictly observed. To protect the
environment we use the best possible technology and materials, subject
to economic considerations.
Packaging
Where packaging is concerned, we participate in country-specific
recycling systems that ensure optimum recycling. All of our packaging
materials are environmentally compatible and can be recycled.
Used appliances
Old appliances contain materials that should be recycled.
The relevant assemblies are easy to separate and all plastics are
identified. In this way the individual assemblies can be easily sorted and
directed to recycling or disposal.
