13 Environmental protection and disposal
Environmental protection is a fundamental corporate strategy of the
Bosch Group.
The quality of our products, their economy and environmental safety are
all of equal importance to us and all environmental protection legislation
and regulations are strictly observed.
We use the best possible technology and materials for protecting the
environment taking account of economic considerations.
Packaging
Where packaging is concerned, we participate in country-specific
recycling processes that ensure optimum recycling.
All of our packaging materials are environmentally compatible and can be
recycled.
Used appliances
Used appliances contain valuable materials that can be recycled.
The various assemblies can be easily dismantled. Synthetic materials are
marked accordingly. Assemblies can therefore be sorted by composition
and passed on for recycling or disposal.
Old electrical and electronic appliances
This symbol means that the product must not be disposed
of with other waste, and instead must be taken to the waste
collection points for treatment, collection, recycling and
disposal.
The symbol is valid in countries where waste electrical and
electronic equipment regulations apply, e.g. "European Directive 2012/
19/EC on old electronic and electrical appliances". These regulations
define the framework for the return and recycling of old electronic
appliances that apply in each country.
As electronic devices may contain hazardous substances, it needs to be
recycled responsibly in order to minimize any potential harm to the
environment and human health. Furthermore, recycling of electronic
scrap helps preserve natural resources.
For additional information on the environmentally compatible disposal
of old electrical and electronic appliances, please contact the relevant
local authorities, your household waste disposal service or the retailer
where you purchased the product.
