DEHN and Environment

DEHN protects. This guiding principle also applies to our commitment to environmental protection. Since 2000 we have had an environmental management system in place which is certified according to DIN EN ISO 14001. Since 2020, our energy management system has also been certified according to DIN EN ISO 50001.

Product conformity

Of course, we also feel responsible for our products during their service life. For this reason, the vast majority of DEHN products comply with substance restrictions above and beyond the legal requirements.


The RoHS2 Directive (Directive 2011/65/EU with the Delegated Directive (EU) 2015/863) restrict the use of certain hazardous substances in electrical and electronic devices. These comprise lead, cadmium, mercury, chromium(VI), polybrominated biphenyls (PBB), polybrominated diphenyl ethers (PBDE), di(2-ethylhexyl) phthalate (DEHP), butylbenzyl phthalate (BBP), dibutyl phthalate (DBP) and diisobutyl phthalate (DIBP).

We strives to implement these substance limitations - partly by making use of exemptions - in almost all DEHN articles, although only a part of our product portfolio is actually subject to the scope. Information on compliance with the RoHS2 directive can be found in the EU declarations of conformity for articles that fall within the scope.


The REACH Regulation deals, among other things, with the duty of suppliers of products to provide commercial consumers and end consumers with information. If a product contains a ”substance of very high concern” (SVHC), which is listed in the Candidate List of the European Chemicals Agency (ECHA), in a concentration of more than 0.1 wt.-%, sufficient information shall be provided to enable the safe use of the product – however, the minimum requirement is to name the substance. The Candidate List, which is updated at regular intervals, can be viewed on the ECHA homepage (

Professional and environmentally compatible recycling of used devices, spent batteries and packaging material is important to us and reduces the environmental impact to a minimum.

Used devices

The WEEE2 directive (RL 2012/19/EU) regulates the return and recycling of used electrical and electronic equipment in order to recover valuable raw materials. This applies to all DEHN products which are marked with the symbol on the right. In individual cases (small product dimensions) the symbol is only printed in the installation instructions / operating instructions.

Our WEEE registration no. is: DE 69459855


Please note the following differentiation with regard to used devices:

B2C products – Business to Consumer

Some of our devices are used in private households or comparable applications and may not be disposed of in the normal household waste. They must be returned to public collection points (e.g. municipal recycling centres).

B2B products – Business to Business

These devices have been used in the commercial sector and again may not be disposed of in the normal household waste. They should be professionally recycled.

Used batteries

Used batteries may contain harmful substances that could damage the environment and present a health risk. For this reason, they should not be disposed of with the normal household waste. Collecting them separately also makes it possible to recover valuable raw materials from the used batteries.

Please return used batteries or accumulators to suitable collection facilities, e.g. collection boxes of the GRS foundation (Common Recycling System of Batteries). For safety reasons, please tape up the poles of lithium batteries to avoid short circuits.

Product and transport packaging

We collaborate with the company Interseroh Dienstleistungs GmbH with regard to the return and recycling of used packaging material.
