KA11000 REMAC - Renewing Sludge Management Concepts

The Project REMAC aims to develop ecologically and economically sound sludge management concepts in smaller regional towns.

The project REMAC responds to the specific element for improving the people’s physical living environment by providing new methods for ecologically and economically sustainable concepts for wastewater utility sludge treatments for regional towns in relatively dispersed settlements. In many cases, current sludge treatment practices are not carried out on ecologically or economically solid basis.

In Finland, open-pit composting of the sludges is about to end due to existing environmental permit practices. Finland is nationally supporting biogas production, which is implemented nationally as big-volume anaerobic digestion units. Whilst the increase in biogas production supports environmental sustainability, the dependency on centralized high-volume units forms problems in areas with dispersed population. The amount of fossil fuel needed in transportation of the sludge is high due to transportation of even hundreds of kilometers for both the sludge and the digestate from the biogas production process. Wet digestion is also very water-intensive process increasing the need to transport digestate with high water content after digestion process. 

In Russian Karelia, landfilling or open-pit composting of sludge is common practice, leading to uncontrolled methane leakage and leeching of nutrients and possible harmful compounds into soil and nearby waterbodies. There has been a previous investment initiative BIOKOS at Kostomuksha region for developing sludge treatment, based on drying the sludge and incinerating it with woodchip in local district heating plant. The plant is in operation and sludge treatment has been improving due to previous investment, but the drying technologies available during the previous investment are not adequate for effective process. To date sludge is placed to open-pit composting instead of incineration. One problem is also that options for renewing the sludge management without massive investments are not always recognized, nor implemented. Examples of these can be found e.g. in Kondopoga district, where sludges from 5 villages with humidity of 98% are transported. Also, the existing units represent a risk of leaking sludge to nearby waterbodies due to inadequate facilities. This is due to limited availability of technological expertise and systemic understanding on the local context. Also, hand-on understanding on frame conditions related to possible new solutions are not easily available.


Project news

The Project Group consists of following organisations: 

KAMK University of Applied Sciences
Kajaani University of Applied Sciences offers higher education for experts, supports professional growth and carries out research & development activities. KAMK is one of Finland's best and most successful universities of applied sciences in terms of its results, according to the Ministry of Education and Culture. KAMK uses internationalization as a regional development tool. The activities of KAMK R&D are founded in robust specialist expertise, well-functioning partnerships and highly skilled expertise in project work.

Kajaani University of applied sciences coordinates the project ReMaC, and as a lead partner is responsible for the overall project implementation and financial management. It is on KAMK’s responsibility to prepare concept plans for smaller scale shared sludge managing. KAMK has the important duty to report and disseminate project results actively between partners and to the stakeholders but throughout the programme area.

Kostomuksha Town Administration
Kostomuksha Town Administration is the municipal body responsible for city managing and dealing with city development including tourism and event management.

Kostomuksha Town Administration will be responsible for the events conducted in Kostomuksha urban district. There is a rather strong bond between Kostomuksha and Kainuu, so it will be natural and easy to work together in a project like ReMac. The troubles in sludge management is an important talking point in the Republic of Karelia as well as in Kostomuksha. Concerning the project, Kostomuksha Town Administration conducts meetings and negotiations, and benchmarks different businesses in trying to improve the situation with sludge management throughout the Karelia region.
