The anaerobic digestion prototype is installed at the site of IREN Rinnovabili in Roncocesi, located to the north east of the city of Reggio Emilia. Currently, part of the biogas obtained from the anaerobic digestion of waste water treatment sludge is used for the thermal needs of the sludge treatment plant and for the heating of offices (about 400,000 m3/year), while the exceeding quantity is burned in a flare system (approx. 250,000 m3/year). It is planned to use the latter biogas flux for biomethane production.
During plant operation, biogas quality will be monitored before and after the upgrading plant. It is estimated that the plant will be operational for at least 18 months, achieving a total biomethane production of 90,000 Kg/year, sufficient for the refueling of about 8,000 vehicles.
