Products with a Reduced Environmental Footprint

The Group manufactures products and solutions that are mainly composed of:

  • in the Advanced Materials segment: artificial graphite, an inert natural material with no particular impact on the environment;
  • in the Electrical Power segment: ceramic components and recyclable materials (especially copper and silver).

Mersen endeavors to limit the ecological footprint of its products at every stage of their life cycle – from reducing raw materials consumption to producing less waste.
Its approach draws inspiration from a virtuous circular economy model.

Graphite manufacturing:

mirroring “best available technologies” processes

Mersen recycles all graphite waste (powders, shavings, etc.) generated by the production of graphite powder, firing and graphitization and machining, and has also implemented a process for recovering graphite waste from some of its customers.

Paying attention to the social and environmental practices of our suppliers

Mersen’s purchasing charter for a sustainable supply chain formalizes its relationships with suppliers and sets the standard for virtuous collaboration.

It encourages the implementation of best practices – including social and environmental practices – and is accompanied by a CSR questionnaire with a detailed self-assessment grid.

It is available in five languages (English, German, Chinese, Spanish and French).

Mersen takes special care to verify the source of minerals that may be used to manufacture its products and equipment, especially those that could come out of conflict zones.

The Group also has a procedure for evaluating third-party corruption risk, including among suppliers.
