The devices and machines of the Mustankorkea biogas plant are still standing silent in the sparkling new hall. It’s still strangely quiet in the large hall. The final push of the electrical installers is at hand, because everything has to be ready before the testing stage, which is already due to start in the first week of April. In that, the stages of the process will be gone through carefully to ensure operational reliability. After the dry run, the real action will begin when the first garbage trucks bring their load of biowaste to be carried through on the pre-treatment line.

“Before this, the electrical installers still have a lot of work to do,” says the electrical installer Niko Oikari from Loistoset Inc., who strides briskly to the other end of the hall. Fortunately, a moment for a chat can be found even in the midst of the hurry. Oikari says that the greatest challenge of the work stage is the difficult places where the electricians have to get into from time to time to carry out their installations. At other times, they have to go up on the front of the crane to the ceiling of the hall, tens of meters up. The conversation is interrupted by the crane’s beeping warning sound, which tells that a work colleague is once again going up to the ceiling of the hall, holding electrical cables. Six electrical installers are working in different parts of the hall at the moment, taking the work stage to completion.

The new-generation biogas plant will indeed need electricity, when all the functions are fully automated. The task that remains for the maintenance personnel is to monitor from the control room, behind a glass wall, that everything is working as it should. Soon the silence of the plant will end for good when the machines are switched on to convert biowaste into renewable energy.

Biogas is formed in a closed space, in oxygen-free conditions in the four biogas reactors. The process will be started during April 2017.

Before the biogas process, the biomass is pre-treated to reduce the particle size and to separate the organic and inorganic fractions (incl. plastics, metals). In the picture. The pre-treatment line supplied by Ferroplan, which conveys the biomass to the interim storage unit for pre-treated biowaste (seen in the background) before it is fed into the reactors.

Two large gas storages are being built in the vicinity of the biogas plant, as well as a storage for liquid fertilizer.
