The SORG Group was given the responsibility of planning, delivering, constructing and commissioning the first glass melting system of the Wiegand-Glas plant in Schleusingen, Germany. However, what made it challenging was the fact that this major project had to be carried out and completed in the middle of the global Covid-19 pandemic.
The project required a flexible approach by SORG, who considered the health and safety of the workers of many different companies working within the bustling construction site at every stage.
A regenerative U-flame tub for white glass, featuring a working end and forehearths was especially optimized for the needs of Wiegand-Glas. Two completely sealed doghouses were also built utilising EME-NEND® technology.
The project of rebuilding the entire plant was successfully completed thanks to the exemplary behaviour and expertise of both construction management teams, who were working in close partnership to meet the high customer demands. The complete system represents an industry milestone, with excellent levels of energy consumption, glass quality, emissions and maintenance.

SORG believes in continuous improvement, so to provide their customers with ever refining solutions. A company that listens to their customers and their needs to develop the accurate high-quality solutions and services. SORG is a long-time technological leader and has never been a follower. It has been granted more than 100 patents.
These patents include ground-breaking innovations, such as the VSM® and Deep Refiner®. The Deep Refiner® concept has been reproduced and adopted by many other manufacturers.
Another game-changer was the refining bank. This is an integral part of the FlexMelter®, Boro-Oxi-Melter®, LoNOx®, and OxEcon® furnaces. Very recently, these have been used to produce solar glass. The refining bank has also been implemented on a classic end port furnace, to produce high quality containers.

EME® is one of the leading suppliers of batch weighing, dosing conveying and cullet management systems to the glass industry.
