Stoelzle will undertake a planned hot repair of one of its two flint glass furnaces at the Częstochowa, Poland, production site starting March 9, 2026. The glass-to-glass repair will require 17 days, with a total project timeline of 19 days including hot sealing. All customer orders and deliveries will remain fully supported throughout the process.
“Our customers need cost efficiency, cash discipline, and flexibility more than ever,” said Dr August Grupp, CEO of Stoelzle. “By continuously upgrading our production sites, we enhance efficiency and reliability, enabling competitive cost structures, stable specifications, and agile supply. These investments are ultimately about strengthening our customers’ ability to compete.”
Stoelzle Czecstochowa’s Furnace 1 combines high capacity with modern technology and is designed for reliable, efficient production. It supports both flint and coloured glass, ensuring flexibility for premium spirits and food packaging requirements.
A central improvement linked to the repair is the completion of a new system for dosing external cullet. Once commissioned, this upgrade will enable Stoelzle to significantly increase its recycled glass input—supporting lower energy consumption, reduced CO2 emissions, and progress against the company’s sustainability targets.
The Częstochowa plant is one of Stoelzle’s most advanced and efficient sites in Europe, combining highly automated production with a strong focus on cost competitiveness, value creation and continuous innovation. An integrated decoration facility and in-house development capabilities enable end-to-end solutions tailored to customer needs. The site also acts as a reference model for the company’s U.S. plant in Monaca.
To ensure seamless supply during the temporary furnace shutdown, Stoelzle has implemented extensive preparation measures: safety stock build-up, optimised production schedules, coordinated planning across other Stoelzle plants, and ongoing alignment with key customers.
