Stoelzle has resumed glass container production at its Heřmanova Huť glassworks following the modernisation of the amber glass furnace and production technology.

The restart is the result of one of the site’s most significant investments in recent years, reinforcing Stoelzle’s commitment to reliable, high-quality European manufacturing for pharmaceutical and healthcare customers.

The furnace rebuild took place between August and October 2026. The first glass was produced on 8 October, as planned, with all six production lines running under glass within two weeks and glass container production for customers resuming shortly afterwards.

The project involved a complete rebuild of the end-port amber furnace, including its forehearths and regenerators, an expanded melting area and doubled electrical boosting capacity. The investment also covered upgrades to glass distribution, forming, inspection and packaging equipment. The new furnace can process up to 80% recycled glass (cullet), in line with Stoelzle’s goal of more sustainable glass manufacturing.

The modernised facilities strengthen Stoelzle’s cost competitiveness and production flexibility, helping customers manage increasing cost pressures and respond to changing demand. Combined with European production close to its customers, the investment also supports shorter transport routes and more resilient supply chains.

The project was delivered within the approved investment budget and without any lost-time safety incidents. Collaboration between the Heřmanova Huť team and specialist technology partners was key to reaching these milestones.

“Bringing a glass furnace back into operation safely is a demanding process that requires precision, experience and close teamwork. We are now focused on delivering the quality our customers expect,” said Libor Kraft, Plant Manager at Stoelzle Heřmanova Hut’.

“The modernisation of Heřmanova Huť strengthens our manufacturing network. With more efficient production, competitive costs and reliable European supply, we are confirming our long-term commitment to pharmaceutical customers and their evolving needs,” said Dr August Grupp, CEO of Stoelzle.
Established in 1907, the Heřmanova Huť glassworks produces amber glass packaging primarily for pharmaceutical and healthcare applications, as well as selected food and beverage and miniature spirits bottles.
