Project
WtE Ticino, Giubiasco

In 2008, the most southern waste-to-energy power in plant in Switzerland has been put into operation. Commissioned by the three general contractors of the contract sections Boiler, Flue gas cleaning and Ash Washing, STAG supplied the conveying technology and storage sys-tems for various bulk products. STAG served as an important link and und coordinated these interfaces to the full satisfaction of all parties involved.

 

Since the putting into operation of the overall plant, STAG has been assisting the operating company in stock-keeping, plant optimisation and by providing annual service operations, thus ensuring an optimum operational safety and system availability.

 

The waste-to-energy power plant located in Giubiasco is an excellent example illustrating STAG’s LifeCycle philosophy. STAG supported the general contractors during the projecting and construction phase and afterwards, the operator by ensuring safety and availability based on service backups.
