Hitachi Zosen Inova Will Deliver Grate Combustion Technology for the Padova Waste to Energy Plant


The retrofit project will see Hitachi Zosen Inova work for the first time with Ruths S.p.A. in a vertical consortium to deliver a new and highly efficient line at the existing facility in the north Italian region of Veneto.

Hitachi Zosen Inova (HZI) has formed a consortium with Italian boiler manufacturer Ruths S.p.A (Ruths), where HZI will design and deliver its grate combustion core technology to the new fourth line at the existing Padova Waste to Energy (WtE) facility owned and operated by Gruppo Hera. Ruths will supply the new line’s boiler and will lead the construction and commissioning phases.

Termovalorizzatore di Padova was the first WtE plant in the city, where operations initially started in 1962. Today, the facility consists of three combustion lines, the third of which commenced operations in June 2010.  However, the first and second lines have now reached the end of their operating lives and will be replaced with a new and highly efficient fourth line, capable of treating non-recyclable municipal waste and generating 43.6 MW of thermal energy to power homes and businesses.

The retrofit project is key to replacing lines 1 and 2, but importantly it will utilise the latest WtE technology on the same site in Padova.

“HZI is delighted to be working in partnership with Ruths to deliver a new and highly efficient fourth combustion line at the Termovalorizzatore di Padova Waste to Energy facility,” said Fabio Dinale, EVP Business Development at HZI. “This is a very important project for HZI and demonstrates that our grate combustion technology is being sought out by clients for retrofit projects as well as new build Waste to Energy projects around the world.”

“Ruths is glad to design, produce and deliver a new Waste to Energy boiler for the new line of the existing Termovalorizzatore di Padova Waste to Energy site. This demonstrates the high reliability and the high performance of our boilers, thanks to the great experience gained in this sector for over 20 years and, particularly, after the successful results obtained by the previous line 3 designed and manufactured by Ruths in 2010,” said Agostino Calcagno, CEO at Ruths. “Ruths is pleased to provide Hera with the new line 4 in cooperation with Hitachi Zosen Inova, a worldwide leader in Waste to Energy grates systems, in order to supply a very high-technological product for this important Italian site.”
