Italy destination for HZI’s Kompogas biogas plant installation no. 100

Swiss waste-to-energy (WtE) and biogas technology specialists Hitachi Zosen Inova AG (HZI) has announced that it is joining forces with Cesaro Mac Import (CMI) to build a seventh Kompogas biogas plant in Italy. This anniversary project, which the project partners will deliver in Reggio Emilia for Iren S.p.A by December 2022, marks the 100th installation based on the tried-and-tested dry anaerobic digestion (AD) technology and a further milestone in the evolution of the technology.

HZI’s Kompogas dray AD technology has been deployed around the world since the first installation in Rümlang, Switzerland in 1992, including (top left) Jönköping (Sweden), Doha (Qatar), Kyoto (Japan), and San Luis Obispo (USA). Installation no. 100 will be in Reggio Emilia (Italy), a country with already six Kompogas biogas plants (photo courtesy HZI).

The Kompogas dry AD process originated in Rümlang near Zurich, Switzerland where the very first installation went into operation in 1992. The 100th biogas plant featuring Kompogas technology will be built for Iren in Reggio Emilia, around 140 km south of Milan under the lead of CMI, a key player in the Italian waste management business and a longstanding market partner of HZI in Italy.

With know-how gathered in the course of six joint projects and complementary capabilities, the cooperation partners made a persuasive bid for the contract tendered by Iren.

The last few years have shown that by combining our offerings we’re able to offer pinpoint solutions for Italy’s waste and energy management needs. This makes it even more gratifying that the 100th Kompogas plant isn’t just being built in Italy, but with our trusted partnership, said Luigi Cesaro, Director CMI and Stefano Boscolo, Director Sales Renewable Gas at HZI in a joint comment.

The installation is one of the most technologically advanced projects delivered by HZI in Italy on the basis of its dry anaerobic digestion process.

Four PF2100 digesters will ultimately process 100 000 tonnes per annum of the organic fraction of municipal solid waste (OFMSW) and green waste to produce around 16.7 million Nm3 per annum of biogas. The biogas will then be upgraded into biomethane aka renewable natural gas (RNG).

This is the first time HZI is building this size of digester in ferroconcrete, scaling up the design to optimally meet the client’s requirements, local conditions, Italy’s current regulations, and the special geographic features of the site.

Engineering had already begun by the end of 2020 with the plant scheduled to go into operation in December 2022.
