The Biona Gas project is a biogas plant with a capacity of 1.5 MWe, mainly based on the input of liquid cow manure with co-products as silage corn and straw.

Situated in the village of Tsalapitsa, the 1.5 MWe biogas plant is built with a solid feeding system, a liquid input system consisting of a pump and cutter, 2 digester tanks in combination with an after-digester tank, a separator system, after-storage tanks and a building with a control and heating room, a 1.5 MWe CHP and a room for the operator.

A high efficiency is realized by applying 2-step digestion with an after-digester tank together with a high quality type of mixing.


Start construction October 2013
Start-up / commissioning June 2014


Capacity ± 40,000 tons / year
Input streams Mainly liquid cow manure, silage corn and straw
Liquid input The liquid cow manure is brought into the digestion process by a cutting and pump system from the shed to the digester tanks
Solid input 80 m³ mixing and dosing bin with input screws to the digester tanks
Digester(s) 2 x 2,280 m³
After-digester(s) 1 x 2,280 m³
After-treatment The digestate is seperated by a seperator into a thin and thick fraction. The thin fraction is stored in 2 x 4.592 m³ after-strorage tanks.
CHP(s) 1.5 MWe with flue gas cooler in building


  • The plant runs on high organic load (1.5 MWe from 4,560 m³ main digestion volume)
  • Flexible plant for various input streams
  • Digestion of straw / manure
