4 Elements

Sustainability for Freudenberg is not just a passing trend: It has always been anchored in the company’s values. So environmental protection is key to our global strategy. In our daily lives, the steps we take to protect the environment are not always dependent on expensive machines or wide-ranging process changes.  Four examples from the Freudenberg World showcase the solutions that allow our customers to unlock the enormous potential from existing technologies. We use leading technologies in this way to reduce CO2 emissions and help protect society and the environment.


Things can get hot in rotary kilns – very hot, in fact. For example, when it comes to manufacturing cement, the mercury often rises above 1,000 degrees Celsius.

Despite these “volcanic” conditions, sealing systems from EagleBurgmann, a Freudenberg Group company, make lasting contributions to environmental protection, energy efficiency and process safety.



Keeping machines and plants perfectly lubricated is akin to a balancing act: in terms of energy efficiency, the lubricant’s viscosity has to be as low as possible, so as to keep friction and energy losses to a minimum. At the same time, its viscosity must be sufficiently high to prevent direct contact between a shaft and bearing during operation, preventing wear and breakdowns. The better a lubricant combines these opposing demands, the more efficiently a system runs.



Against the backdrop of increasingly stringent air pollution thresholds, Freudenberg Sealing Technologies has a long-standing reputation for providing automakers and commercial vehicle manufacturers with a range of sealing technology innovations that reduce both fuel consumption and harmful combustion engine emissions. At the same time, the company has accelerated expansion of its product portfolio in electromobility – with individual sealing components, and complete battery and fuel cell technology system solutions.



When it comes to deep borehole drilling, the worst-case scenario is a blowout, where liquid, oil or natural gas is uncontrollably released into the environment. The images of Deepwater Horizon in the Gulf of Mexico, one of the worst environmental catastrophes in history, are still engraved in our memories.

Blowout preventers (BOPs) are designed to avoid precisely such a worst-case scenario.
