Biotehdas about Kuopio biogas plant and partnership with Watrec.
Kuopio biogas plant under construction.
Biotehdas Oy is Watrec’s partner, a company which owns and operates the Biotehdas biogas plants Watrec designs and constructs. Today Biotehdas is building a biogas plant network which can fully provide the regions of Finland with modern biowaste solutions from Watrec Oy. Kuopio biogas plant is one of the chain.
There was a high demand in Kuopio region for up-to-date efficient waste treatment solutions. Kuopio region had a real need for organic waste management services and Kuopio biogas plant is now taking care of this task – performing at the same time both environmentally and socially responsible. The plant is at service of the municipalities and industries of Pohjois-Savo region.
During construction period Watrec was working in cooperation with Biotehdas. According to Eeli Mykkänen, development manager of Biotehdas Oy, “The time schedule was followed very well. The target was achieved according to the plan. There were no mistakes. Everything was organized in a way it should have been organized and now goes really smoothly. During construction period the supervising works have been done very well.”
The plant is operating from March 2014 (waste water sludge) and in April 2014 – biowaste pre-treatment system has started its work. First biogas transfer was organized already in May 2014. The operation is still controlled by Watrec personnel. Some process units are still on testing period. Maximum capacity of Kuopio biogas plant will be achieved quite soon.
“We are pretty much satisfied with the processes of the plant. The waste pre-treatment processes work very well. Non-organic materials are easily removed, that is why now we can treat many types of materials. It is good for our customers. Well-developed pre-treatment process widens the variety of the wastes and brings more customers.” – mentioned Eeli Mykkänen.
Plant processes today
End products of Kuopio biogas plant are biogas and organic fertilizers. The produced fertilizers are high-quality products, full of nutrients, containing no inorganic components. “Now we provide fertilizer products to the farmers of Kuopio region and mould manufacturers.”
The biogas is delivered through a 5-km pipeline to Kuopio Energy that produces heat and electricity for Kuopio city. Gas supply is now in testing period. Kuopio Energy motor CHP unit is tested at the moment and will soon provide energy to 1500 private houses.
Partnership with Watrec.
Eeli Mykkänen, development manager of Biotehdas Oy:
“It has been very easy to communicate with Watrec people, and the project went in very close cooperation. Tight time schedule was the only challenge. The project was very well organized, starting from planning and construction and ending up with operation and maintenance. We trusted to Watrec’s experience from Vambio biogas plant. We are happy to start new project with Watrec as everything is working well. We have already constructed several successful plants together and plan to proceed the same way in the future. It has been very important for biogas plant projects to use consultancy services from Watrec. Environmental permission processes prepared by Watrec went smoothly and quickly. And the most important thing is that Kuopio biogas plant is economically efficient plant.”
“It is important that the plants and the technologies are working without any interruptions and break downs. Watrec has designed the plant in a way that it is easy to keep the process and all the equipment in good condition”.
Harri Manu, production engineer of Biotehdas Oy:
“The most important thing about biogas plant is that the reception always works – that we can take sludge and waste. We can’t say to our customers “take it another place”.
