After just less than two years of construction, Hitachi Zosen Inova handed over the new Kompogas® plant in Högbytorp, Sweden, to E.ON Biofor Sverige AB. The instal-lation will process the region’s organic waste to generate high-grade biomethane, compost, and liquid fertilizer.

On the same day as launching the project to build a Kompogas® plant in Jönköping on 1 March, Swiss-based Hitachi Zosen Inova (HZI) has now notched up another success in Sweden: after around 18 months of construction and commissioning, the Kompogas® installation in Högbytorp, around 40 kilometers north-west of Stockholm, has now been successfully handed over to the client, E.ON Biofor Sverige AB. “I am glad to operate a plant that’s built and runs so well,” said M. Lindblad, Plant Manager at E.ON, at the handover. The biogas plant at Högbytorp was HZI’s first Kompogas® project in Scandinavia.

Now the installation’s three steel digesters will treat around 83,000 metric tons of kitchen and organic waste every year, as well as organic material from agriculture, to produce 6.8 million Nm3 of biomethane annually – substituting around 7 million liters of fossil fuels. The facility will also produce 6,500 t/a of compost and a further 50,000 t/a of liquid fertilizer for local nurseries and farms.

Part of the renewable energy park in Högbytorp, the installation will contribute to the implementation of Sweden’s decarbonization initiative, launched in 2015, and its goal of becoming the first country in the world to do completely without fossil fuels.
