January 23, 2026: Germany’s PENOX Group has paid tribute to former CEO Giso von Steinau-Steinrück, who has died aged 65.

The lead oxides and additives company announced the death on January 20.

Von Steinau-Steinrück died in Paris last November and a memorial service was held in Germany earlier this month. He spent the last 17 years working as an independent consultant and most particularly working in Brazil, India, Mexico and South Africa. In addition to offering business development strategies he was involved in recycling projects.

Giso will be remembered as he played an essential role in the creation and development of PENOX, formerly the Penarroya Oxide Group, the firm said.

“Over more than two decades, his commitment and contribution left a lasting mark on the company and on all those who had the privilege to work with him.

“Giso’s vision, drive and leadership were instrumental to the future success of the firm, which was created by the merger of the lead oxide activities of Heubach & Lindgens and Metaleurop in October 1994.”

The merger brought together lead oxide production and experience in the fields of red lead, litharge, battery oxide as well as plant engineering.

“From the mid-1980s until the early 2000s, Giso dedicated his energy and passion to this industry to build a unique group that continues to supply high-quality lead oxide to customers around the world.”

Today, PENOX is one of the world’s largest producers of lead oxides, with operations in Germany, Spain, Mexico and South Korea.

In addition to lead oxides, the company said it has increasing sales in activities such as battery additives and R&D on behalf of clients.
