Sorg will supply equipment for the hot end of Vetropack’s glass plant in Boffalora sopra Ticino, Italy.

The CHF 400 million Italian glass plant will be Vetropack’s first greenfield project. The Sorg Group is supplying two regenerative end-fired furnaces with forehearths, the entire batch plant, and a complete service package. The two melting furnaces will produce white and cuvée coloured container glass.

The Sorg Group will supply the complete melting furnace from a single source as a turnkey project, including cabling, piping, project management, installation, and commissioning.

Nikolaus Sorg

Nikolaus Sorg planned and supplied the melting furnace – which were modelled in detail with Vetropack, as well as the glass conditioning systems and all necessary equipment.

The plants are designed to achieve maximum efficiency with the lowest energy consumption and minimal emissions.

For example, the furnaces will have a high amount of electric boosting, which can be further increased at a later point in time.

The combustion process is controlled and regulated by means of a gas analyser, burner with individual nozzle regulation, WSH-type burner holder and double continuous flue gas measurement (chamber head and flue gas duct).

For further control of the processes, the two doghouses per furnace are sealed against gas and dust by using EME-NEND R2 batch charging machines.

Each furnace is equipped with four type 340S+ forehearths.

The Sorg OMT measuring and control system is installed in all zones of the forehearths and the working end to ensure optimal combustion.

All systems are also regulated and controlled via a PCS7 system.


In addition to the four EME-NEND R2 charging machines, EME is supplying the batch bunker, the charging platforms, and the steel construction for this area.

SKS in the form of SKSI, responsible for service in the Sorg Group of companies, will supply all the furnace and forehearth steel, a total of 1,500 tons.

Furthermore, it is responsible for the refractory storage, erection of the steel and refractory structure as well as heating-up, filling and commissioning of the furnace.

The Power of Three

The Sorg Group – The Power of Three – will supply the complete design and plant technology for the hot end of this greenfield project, consisting of the glass melting furnace, glass conditioning section and batch supply, all from a single source.

The group will also handle all project management, from refractory storage to the handover to the customer.
