In a major step forward for sustainable glass manufacturing, SORG Group has completed the full reconstruction of the AV3 furnace for Vidrala at its production facility in Llodio, Spain. Vidrala, a leading European glass packaging producer, partnered with SORG to upgrade the regenerative end port furnace originally built by SORG, enhancing its performance and environmental footprint.
The AV3 furnace is designed for container glass production in multiple colours. The rebuild modernised the furnace with cutting-edge furnace engineering, featuring increased use of electric energy alongside traditional gas heating. This hybrid approach reduces carbon emissions and supports Vidrala’s commitment to energy-efficient production.
SORG delivered a complete suite of systems including combustion air and waste gas units, electrical heating, and dual-redundant SCADA control for precision operation. Glass conditioning systems such as the STW working end and 340S+® forehearths were also installed, ensuring consistent glass quality. Batch charging was managed by EME’s advanced EME-NEND® system.
Construction was led by SKS, which handled demolition of the old unit, refractory installation, steel construction, and final commissioning tasks like ceramic welding and hot insulation. 
This project underscores the importance of innovation and collaboration in the glass industry. By combining reliable furnace design with modern energy strategies, SORG and Vidrala demonstrate how traditional manufacturing can evolve toward sustainability.
As glassmakers across the globe face growing pressure to decarbonise, projects like AV3 set a benchmark for how to modernise production while maintaining quality and efficiency.
