Yesterday on 13.7, the City of Kotka celebrated the opening of the The Tall Ships Races 2017 event with its own contribution towards improving the state of the Baltic Sea.  The City of Kotka, Kotka Maritime Research Centre and Kymen Vesi Oy have compensated for their nutrient emissions in the NutriTrade project.


Kymen Vesi Oy has in Mussalo, Kotka, Finland’s fourth largest municipal wastewater treatment plant.  The plant deals with the wastewater from about 90,000 inhabitants of the areas of Kotka, Pyhtää, Hamina and the former Anjalankoski, as well as industrial waste water from the same areas.

Even though the wastewater is already being cleaned in an extremely effective way, it is practically impossible for any operator to be able to produce a result that is completely nutritionally neutral.

To compensate for the annual phosphorus emissions of more than 2.3 tonnes, the City of Kotka, Kotka Maritime Research Centre and Kymen Vesi Oy support a reduction in phosphorous emissions by a total of 10,000 euros in the town of Kingisepp in northwest Russia, as well as the local fishing project.

This will reduce the phosphorus emissions into the Baltic Sea by over 2.3 tonnes, i.e., an equivalent amount to the annual emissions of the Mussalo plant.

Kotka’s efforts into cleaning up the Baltic Sea will be announced at a specialist Baltic Sea seminar on 14.7, organized in connection with The Tall Ships Races.


The support provided by Kotka is targeted towards the acquisition of a chemical tank for the Kingisepp wastewater treatment plant.  The Kingisepp plant has a joint venture with the John Nurminen Foundation, whereupon it commits itself to the level of wastewater treatment recommended by the Baltic Marine Environment Protection Commission, Helcom.

The idea of ​​the compensation is to use a sum of money on a less efficient water treatment plant, as it will have a greater impact on the state of the Baltic Sea than in Mussalo, where phosphorus is already effectively removed.

In addition, operators in Kotka also support the Finnish local fishing project, piloted in the NutriTrade project after its EU funding has expired.

The local fishing project focuses on the fishing of carps and minnows.  The objective is to recycle a significant amount of nutrients from the sea onto the land, while, at the same time, promoting the use of domestic fish as food.


In Kymenlaakso, industry and water plants have carried out long-term efforts towards the reduction of nutrient emissions.  Kymen Vesi Oy was founded 10 years ago, and the Mussalo wastewater treatment plant began to operate at full power in 2010.

The managing director of Kymen Vesi, Jani Väkevä, stresses that the investment in the wastewater treatment plant has really paid off: a modern, centralized wastewater treatment plant was built to replace seven local treatment plants.  Kymen Vesi is now often able to perform cleaning tasks at even higher standards than that which is required by the authorities.

There are many significant industries in the Kymenlaakso region, and the Mussalo wastewater treatment plant has also offset the loads produced by industry.  On the other hand, large forest industry companies also have their treatment plants.

“The nutrient load in the Gulf of Finland has dropped dramatically over the last ten years.  This is reflected in the lowering of both the concentrations of phosphorus and the levels of algae, especially in the eastern part of the Gulf of Finland.  The most positive developments have been influenced by measures taken in St. Petersburg, and a phosphorus fertilizer factory in Kingisepp.  Thanks to the extensive renovation of the Mussalo wastewater treatment plant in Kotka, the eutrophic load into the nearby waters of Kotka-Hamina has also dropped significantly.  When compared to the situation a decade ago, the phosphorus load from municipal wastewater has decreased by more than 40%, and the nitrogen load by more than 60%, “says special researcher Seppo Knuuttila, SYKE.

‘The obvious clearing of the sea area of Kotka over the past ten years is magnificent proof that with determined action, we can improve the state of our living environment during our own lifetime, “says Marjukka Porvari, who leads the environmental projects of the John Nurminen Foundation.


“It’s great to have the marine Kotka involved in the NutriTrade project to neutralize phosphorous footprints.  We hope that the example shown by Kotka will inspire other Finnish cities to seize the issue, “says project manager Anna Saarentaus, responsible for the NutriTrade projects of the John Nurminen Foundation.

Kotka is now the second city to neutralize its nutrient emissions.  The first was piloted by Helsinki, which launched a co-project in 2016 in Vitebsk in Belarus.

The Nutribute group funding base created in the NutriTrade project will serve as the first voluntary nutrition emission trade system for the Baltic Sea and Europe, as a whole.  It will enable cities, businesses and citizens to neutralize their nutrient emissions.

“The Nutribute group funding base under construction will enable cities, businesses and citizens alike, in the future, to find and participate in emission reduction projects of interest” emphasizes Saarentaus.


Discussions concerning the state of the Baltic Sea will be open to everyone in the open Baltic Sea village, which is located on Itälaituri in Kantasatama. There, visitors will get to try the effect of their own choices on the state of the Baltic Sea with, among other things, the assistance of the  Baltic Sea- calculator.

Kymen Vesi will commemorate its 10th anniversary of operations by offering coffee and cake to visitors at the Baltic Sea village on Thursday 13 July, from 5pm to 7pm.
