Contract for realisation of a 10,5 MW biogas plant with Mutluar enerji Gönen

We are pleased to announce that after we have built Turkey’s largest biogas plant in Suluova with 6.637 MWh last year, we are  involved now in the construction of a larger biogas plant.

We have agreed with our customer Mutlular enerji on the execution of the first line of the 10.5 MW project in Gönen.

After we developed the planning for the project last year, we are now looking forward to realizing the project together with Mutlular Enerji. The first line with more than 6 MW should go on grid in 2020.

Project Gönen, Turkey – our first fermenter with concrete dome roof!

At our biogas plant Project in Gönen (Turkey) we are currently building our first fermenter with a concrete dome roof.

This roof form is manufactured with special formwork systems.

Due to the well-thought-out static dissipation of the support forces, there is no center column, since everything is supported by the outer walls.

This has several advantages over a system with center support such as:
– more volume available for the residence time
– substrate can be better homogenized
– concrete -, formwork – and coating works of the center column are not necessary anymore.


New projects in Turkey

Our new customer Efeler Grup gives us his trust and realizes together with us 2 new biogas plants in Turkey (Akyurt and Cubuk).

Each plant has a capacity of 3.002 kWel. Chicken dung and cattle manure are used as input materials.

We thank you for the order and look forward to the cooperation!
