First biogas plant of a turkey farm in Finland 

The first biogas plant of a turkey farm in Finland, located in Kurikka, Southern Ostrobothnia, was completed at the end of 2021. The plant processes turkey manure, straw and grass, all of which are farm’s own feeds. No slurry is used at the plant. Such a liquid manure-free concept is well suited for poultry farms that, for hygienic reasons, cannot receive feed stocks of animal origin outside the farm. Gas is first used for heat production of the farm’s own need and later CHP is added to the combined heat and power generation.   

Metener delivered the process design and technology for the dry batch digestion plant. The gas burner started 2 weeks after addition of inoculate, ie the process rose faster than estimated 1 month.

Gas tractor refuelling system, Agco Power Oy

Metener delivered remote gas concept to Agco Power. System includes mobile high pressure gas storage, gas pipes, automation, safety systems and refuelling nozzle. System is designed and installed by Metener.

Biogas upgrading unit and filling station

Biogas upgrading unit 300 m3/h and filling station to Säkylä, Finland.

Gas system for testing CNG-engines

Metener desinged and installed gas system (bottles, pipes) according to Atex legislation, for CNG-engine testing room. System was approved by authorized inspection office.

Palopuron Biokaasu Oy dry fermentation plant in Hyvinkää

Constructed and commissioned in year 2018. Produces 2500 MWh traffic gas per year using grass, horse and chicken manure as biomasses. Biogas is upgraded to biomethane and pressurized to 250bar using Metener own developed systems. Biomethane is sold for vehicle use at Nivos Energy public filling station at Knehtilä farm. Biogas is also used for heating at Knehtilä farm. Palopuron Biokaasu Oy is established by Nivos Energy Oy, Knehtilä farm, Metener Oy and Lehtokumpu farm. More information:
