Responsibility and sustainability

Sustainability Responsibility for the Environment and Resources

DÖRKEN develops products and services with the goal of using resources efficiently and reducing environmental impact. We base our approach on applicable legal requirements as well as internal standards in the areas of production, storage, and disposal.

In addition to technological progress, we integrate environmental and resource protection as integral components of our development and production processes.

Well-engineered Developments

The companies within DÖRKEN develop products and services according to defined testing and approval processes. New developments are systematically evaluated for quality, safety, and selected environmental aspects.

In doing so, we consider, among other things, the impacts of materials, processes, and applications in their respective usage contexts. Products are only introduced once they meet the specified internal requirements.

The goal is to develop solutions that meet functional requirements while also taking into account aspects such as resource efficiency and durability.

Safety High standards and a precise observance

“Safety is paramount! – this is the motto at each of our production sites. We use high technical standards to protect our production facilities and our environment. To achieve this, we use, amongst others: gas warning systems, temperature and pressure warning systems, flame traps, fire alarm systems and a drainage system that can be uncoupled from the public grid if necessary.

In addition to the purely technical measures, we also think further: we invest continuously in safe and environmentally friendly further developments and regularly train our employees in safety aspects. Consequently, observing all industrial health and safety and fire protection regulations is self-evident for every employee. In addition, all third-party firms that we assign also need to adhere to our high standards and we check their compliance carefully.

We are prepared

Thanks to our safety precautions and our internal quality and safety management, the likelihood of a malfunction impacting the environment is very low. As a company that works with chemical substances, we are nonetheless unable to guarantee one hundred percent safety.

For this reason, we have drawn up an internal and external emergency management system that works closely with the local fire service to specify suitable measures for dealing with malfunctions and limit their impact in the event of an incident. With our works emergency service and the works crisis team we can join with the authorities in tackling possible incidents in a professional manner and averting the impact on people and the environment as best possible.

Certification We have ambitious goals

The use of our quality management system is good for our company, for our employees and for our environment. To meet the goals set by both the authorities and ourselves we work with a system at DÖRKEN that combines and unites specifications regarding quality, safety, environmental protection and fire protection.

By observing strict requirements and consistently setting ambitious goals we have been certified according to DIN EN ISO 9001 and 14001 for decades. In addition, all DÖRKEN companies voluntarily participate in the EMAS eco audit, thereby committing themselves to the continuous further development of company environmental protection, including beyond the statutory requirements.
