Äänekoski, Finland

This biogas upgrading installation in Äänekoski in central Finland is placed at ‘Bioproduct Mill’, a ‘new generation’ bioproduct mill built by bioproducts manufacturer Metsä FibreThe biogas is produced from forest-based slurries from pulping process.

The installation upgrades the 250 Nm³/hr produced biogas to 150 Nm³/hr biomethane, which can easily be expanded to 350 Nm³/h biogas and 210 Nm³/h biomethane. The plan is to use the green gas for a CNG filling station, that is likely to be built along the main road. The gaseous CO2 from the upgrading will be used for the neighbouring paper mill which produces approximately 1.3 million tonnes of pulp annually.
