Dry fermentation specialists, Switzerland-headed energy from waste technology provider Hitachi Zosen Inova AG (HZI) has announced that in collaboration with its Italian partner Cesaro Mac Import (CMI), it is to build a new Kompogas plant in Foligno, a town in the province of Perugia, Italy. The plant will an annual capacity to process 40 000 tonnes of biowaste and 13 500 tonnes of green waste to produce biomethane.
Scheduled for completion at the end of 2018, the plant will be the fifth Kompgas facility to be built in Italy. Together with the composting technology from CMI, the dry anaerobic digestion (AD) technology provided by HZI will form the core of an overall concept aimed at processing and profitably recycling local organic waste.
Fifth joint project
According to a statement, the regional biowaste (SSO or ‘FORSU’) and green waste will be processed using dry anaerobic digestion and composting technologies to deliver the best possible yields. While the biogas produced will be upgraded to valuable biomethane, the digestate will provide nutrient-rich liquid fertilizer and high-grade compost for use in agriculture.
Foligno is HZI’s fifth project with its Italian partner CMI, a market leader in dry anaerobic digestion in Italy. CMI was awarded the order to execute this project by ASJA Ambiente Italia SpA in July 2017. HZI and CMI signed their contract in September 2017, underpinning the successful collaboration between the two firms.
Upgrading to biomethane
HZI will deliver the AD section of the plant, consisting of two PF1300 steel digesters with the corresponding technology, including the control system. The digestion process will produce more than 14 000 Nm3 of biogas per day, which will subsequently be upgraded into biomethane and fed into the local gas grid or sold as an environmentally friendly fuel in the form of compressed biomethane gas (CBG or bio-CNG).
We are proud that both CMI and ASJA have once again placed their trust in us with this project. We are convinced that Foligno will mark a further successfully executed project for us in Italy, thus enabling us to maintain and bolster our market position, said Bernard Fenner, Vice President System Unit AD at HZI.
