Stoelzle Glass Group has announced a planned hot repair of one of its two flint glass furnaces at its Częstochowa production site in Poland, with works scheduled to begin on March 9. The glass-to-glass repair will last 17 days, with a total project timeline of 19 days including hot sealing.

The intervention focuses on Furnace 1, which supports the production of both flint and coloured glass, serving premium spirits and food packaging markets. By executing the repair without a full shutdown, Stoelzle ensures operational continuity while extending furnace campaign life and maintaining high production standards.

According to Dr. August Grupp, CEO of Stoelzle, the investment reflects the company’s continued commitment to operational efficiency and customer competitiveness. He emphasised that upgrading production infrastructure strengthens reliability, cost structures and supply agility, key priorities in today’s demanding market environment.

A central upgrade linked to the project is the completion of a new external cullet dosing system. Once commissioned, the system will increase recycled glass input, contributing to lower energy consumption and reduced CO₂ emissions. This move aligns with Stoelzle’s broader sustainability strategy and decarbonisation roadmap across its European operations.

To ensure seamless supply during the temporary furnace intervention, Stoelzle has implemented comprehensive preparation measures, including safety stock build-up, optimised production scheduling, coordinated output across other group facilities, and close alignment with key customers.

The Częstochowa plant, which also includes an integrated decoration facility and in-house development capabilities, plays a strategic role within the group and serves as a reference model for Stoelzle’s U.S. operations in Monaca.
