We have built a reputation as a reliable partner since 1919. To continue handling the increasing complexity of materials, we are committed to research and development and creating sustainable processes and technologies.


We have a long tradition of innovation. Since 1919, we have developed new and unique technologies for our refining and smelting processes.

We continuously feed our ‘Furnace of Innovation’, both through the recycling of increasingly complex raw materials as well as through new technological ideas about the refining processes.
