We’re changing the world.


Sintex assuming responsibility

Powder metallurgy is recognized as a green technology, and at Sintex, we are working on reducing the number of processes within several areas – not only to ensure a sustainable technology, but also to streamline and optimize our solutions in high-volume production.

At Sintex, we are aware of the future – through Rethinking Components of Tomorrow, as well as doing so in a sustainable matter.
In general, our processes within powder metallurgy are environmentally friendly, but to meet future environmental requirements, optimization in the value chain is also necessary. That is why we, in collaboration with Air Liquide, take action in Power-to-X. Through this collaboration, we have taken a big step towards CO2-neutrality in our gas supply. The production facility at Air Liquide ensures a very high quality of hydrogen, guaranteeing an exceptional quality in our sintered stainless-steel products.

Our sustainability journey

The following graph presents our CO2-emissions relative to our production of powder metallurgical components.

As the graph demonstrates, we have been operating in a sustainable matter for many years. Below, we have highlighted some of our sustainable initiatives since 2009.




We developed the IP-magnet. The first epoxy-free magnet for Grundfos' pumps was introduced which:

  • ensures an epoxy-free working environment
  • increases engine performance in high-end products yielding a remarkable annual CO2-reduction for our customers
  • is designed according to the Cradle2Cradle principles therefore is reusable after the service life
  • included in the production of approximately 200,000 pumps every year.


Local agreements

We entered into an agreement with the local energy supplier, Verdo, to produce firstpioneer in producing North-European green hydrogen, that is, hydrogen produced by pure wind energy. Sintex installed a pipeline and turned our hydrogen supply from black to green, thereby reducing the annual CO2 emission by 1 kg per Nm3 hydrogen.



Green magnets

Within the frames of Green Magnets project, in collaboration with Aarhus University and Danfysik, we developed next-generation super magnets for particle accelerators, C-14 detection and CT-scanners, solely based on permanent magnets. When using permanent magnets instead of electro magnets, you save energy on power for the magnets as well as cooling.

In collaboration with the Danish company Haldor Topsøe, Sintex has developed a new technology for transforming one of the major power-consuming processes in the chemical industry, known as SMR, into an electric-driven version called e-SMR. A demonstration plant was built in 2021, and industrialization is expected to take place over the coming years, reducing CO2-emission in chemical industry by thousands of tons annually.
