Novelis said 10 of its manufacturing plants have achieved the first of four levels of certification in the Novelis Operating System (NOS) as of the end of fiscal year 2026.

Based on the principles of leading manufacturing operating systems, the company customized NOS specifically for the manufacturing requirements of aluminium rolling and recycling plants.

While Novelis has long had a continuous improvement focus, NOS standardises the approach across its global manufacturing footprint.

"Having world-class operations is fundamental to our business and is essential to our ability to exceed our customers' expectations," said Emilio Braghi, Novelis' chief operating officer.

"Reaching the first level of NOS certification reflects our commitment to safe and consistent execution, operational reliability, and continuous improvement and innovation."

The following Novelis plants earned first-level NOS certification:

Berea, Kentucky, United States

Changzhou, China

Göttingen, Germany

Nachterstedt Recycling, Germany

Nachterstedt Rolling, Germany

Ohle, Germany

Pindamonhangaba, Brazil

Santo Andre, Brazil

Sierre, Switzerland

Yeongju, South Korea

Novelis plans to certify all of its 29 manufacturing facilities in NOS and advance them through the four progressive levels of NOS certification.
