Activity description

STEINERT GmbH is a family-owned company from Cologne, Germany. Its history goes back to 1889, when founder Ferdinand Steinert began using magnetism to recover iron from slag and debris. The company has about 550 employees, an annual turnover of around 200 million euros and subsidiaries in Germany, Australia, Brazil and the USA, plus around 50 sales partnerships and joint ventures.

Technology areas:

  • magnetic separation: overband magnets, magnetic drums and head pulleys, eddy current and wet drum separators
  • sensor-based sorting with X-ray, induction, colour, NIR and LIBS sensors, including the UniSort and KSS ranges
  • digital tools such as AI-based object identification and condition monitoring

In plastics recycling, UniSort machines combine hyperspectral NIR with colour data, sort black plastics by polymer type and separate film materials such as PE packaging. Test centres and start-up and optimisation services complete the offer.
