- In December 2023, Roca Group, in collaboration with Keramischer OFENBAU, successfully commissioned the world's first electric tunnel kiln at its Laufen plant in Gmunden, Austria. This innovative kiln aims to decarbonize ceramic production by eliminating the use of fossil fuels, marking a significant step toward sustainable manufacturing in the sanitaryware industry
- In January 2021, brick manufacturer Vandersanden introduced a new environmentally friendly tunnel kiln at its Tolkamer production site in the Netherlands. The kiln reduces CO₂ emissions by approximately 25% through enhanced insulation and advanced kiln techniques, contributing to more sustainable brick production
- In February 2023, a German consortium initiated a research project to investigate hydrogen as a sustainable alternative fuel for tunnel kiln operations. This effort aligns with Germany's national hydrogen strategy, aiming to decarbonize industrial heat processes
- In September 2023, Steuler Group initiated the construction of a new tunnel kiln at its Höhr-Grenzhausen facility in Germany. This project is designed to enhance production capacity and efficiency, with the kiln expected to become operational by March 2024
- In October 2022, SACMI-Riedhammer launched the TWS Neo tunnel kiln series, emphasizing improved thermal efficiency, reduced emissions, and advanced digital process control. The design incorporates cutting-edge EMS (Energy Management System) technology, achieving up to 30% energy savings
