Circular MuSe - From Presentation to Solutions in Practice
The Circular MuSe pilot focusing on the reuse of sand collected during winter street cleaning was one of the practical solutions presented to COEE 2026 participants during a study visit to Wejherowo. The visit to Ekofabryka Wejherowo demonstrated how circular economy principles can be put into practice and contribute to more efficient use of resources in municipal services.
The final day of the 5th International Conference of Ecological and Environmental Engineering – COEE 2026 was dedicated to study visits, giving participants an opportunity to relate the topics presented and discussed during the conference to concrete solutions implemented at the local level.
One of the sites included in the programme was Ekofabryka Wejherowo, where participants learned about circular economy solutions and practical experience related to their implementation in an urban context.
Circular MuSe pilot in Wejherowo
An important part of the visit was the presentation of the Circular MuSe pilot focusing on the reuse of sand collected during winter street cleaning in Wejherowo. The activity contributes to one of the project’s key objectives – increasing the circularity of municipal services through resource recovery and reuse, as well as developing new approaches to material management.
The visit provided participants with an opportunity to explore the practical dimension of the solution and learn about local experience with its implementation. It also demonstrated how a material previously treated as waste can be considered a potential resource and brought back into circulation.
The experience gained in Wejherowo is also relevant in terms of the potential transfer and adaptation of similar solutions by other cities and municipalities. Combining knowledge exchange, demonstration of solutions and practical implementation experience is an important element of Circular MuSe and supports the development of more circular models for municipal service delivery.

Circular MuSe on Circular Municipal Services at COEE 2026
How can circularity in municipal services be increased and proven solutions effectively transferred to smaller towns and rural areas? These questions were at the centre of the Circular MuSe presentation during the Ideation Project Multi-Forum & Panel Discussion “Circularity in Waste & Water Management”, held on 8 September as part of the 5th International Conference of Ecological and Environmental Engineering (COEE 2026) in Sopot.
Circular MuSe in the discussion on circular municipal services
During the forum, the Circular MuSe approach to more efficient and circular use of resources in municipal services was presented. The project focuses on identifying and transferring proven solutions, developing new approaches through pilot activities, and building the capacities of local authorities and municipal service providers.
The activities are primarily targeted at smaller towns and rural areas in the South Baltic region, supporting local actors in accessing and applying knowledge and experience related to the implementation of circular economy principles.
Circular Municipal Services Hub – knowledge and experience in one place
One of the key elements presented during the forum was the Circular Municipal Services Hub, currently being developed within the project. The Hub is designed to bring together case studies, good practices and circular economy solutions, while providing access to the knowledge and experience behind their practical implementation.
Knowledge transfer is also supported through training, mentoring, study visits and demonstration visits, enabling the exchange of experience among local authorities, municipal service providers, experts and project partners.
Circular MuSe pilot activities
Pilot activities are an important part of Circular MuSe, allowing circular economy solutions to be tested in practice.
One of these pilots is being implemented in Wejherowo and focuses on the recovery and reuse of sand collected during street cleaning. Other pilot activities address the use of sediments from retention basins, as well as methods for their treatment and subsequent reuse.
The practical dimension of Circular MuSe continued on 9 September in Wejherowo, where one of the study and demonstration visits planned within the project took place.
Exchange of experience between projects
The Ideation Project Multi-Forum at COEE 2026 also brought together representatives of other international projects, including CONE, NURSECOAST-II, CURE NbS, GINA, SMARTER, ReNutriWater, GI-mine and SYMBIOTER.
The forum provided a space for exchanging experience on water and circular resource management, nature-based solutions and the mitigation of micropollutants.
Circular MuSe’s participation in the forum combined the presentation of tools and pilot activities developed within the project with an exchange of knowledge and experience on the practical implementation of circular economy principles in municipal services.
Circular MuSe at the COEE 2026 Conference in Sopot
The Circular MuSe project was presented at the 5th International Conference of Ecological and Environmental Engineering (COEE 2026) in Sopot. Prof. Krzysztof Czerwionka from Gdańsk University of Technology presented results of work on the safe recovery and reuse of material collected during street cleaning, including experience from the pilot activity implemented in Wejherowo.
From street waste to resource
During the conference, Prof. Krzysztof Czerwionka from Gdańsk University of Technology delivered the presentation “From Street Waste to Resource: Environmental Safety and Circular Reuse of Street-Sweeping Sand”, focusing on activities carried out within the Circular MuSe project.
The presentation addressed the management of material collected during street cleaning and its potential for safe reuse in line with circular economy principles. One of the examples presented was the pilot activity implemented in Wejherowo.
Circular MuSe pilot in Wejherowo
The pilot tests the washing of material collected during street cleaning in order to recover the sand it contains. The aim is to assess whether material that would normally be treated as waste can, after appropriate treatment, be safely reused.
The activities also include assessing the quality of the recovered material and testing solutions for the treatment of water generated during the washing process.
The Wejherowo pilot demonstrates in practice how solutions developed within Circular MuSe can support more efficient use of resources in municipal services and the implementation of circular economy principles at the local level.
Circular MuSe in the circular economy discussion
The project's presence at COEE 2026 went beyond the presentation of project results. Circular MuSe was also part of the Ideation Project Multi-Forum & Panel Discussion: Circularity in Waste & Water Management, dedicated to the exchange of experience and discussion on solutions supporting circularity in the waste and water management sectors.
Participation in the conference provided an opportunity to share experience gained through the Circular MuSe pilot activities and to exchange knowledge on the potential for wider application of the solutions being tested in municipal services.
Circular MuSe - Pilot Projects and International Expert Review
Circular MuSe is moving the discussion on the circular economy from theory to practice. In Wejherowo, project partners are presenting pilot solutions, discussing technical assumptions, and presenting investment plans. Each project undergoes an international expert review including presentation, technical questions, risk analysis, and recommendations from other partners and invited experts. This method allows rapid identification of gaps, cost optimization, and preparation of scalable models ready for implementation in other cities and municipalities.
Examples of pilot projects and their practical significance • Wejherowo – reuse of sand from winter street cleaning We analyze material quality, cleaning methods, and potential applications in urban infrastructure (e.g. sub-bases, green areas). Benefits: reduced waste, lower raw material purchase costs, and reduced environmental burden. • Denmark – use of sediment from swimming pools Research focuses on safe processing of sediments and possibilities of using them in urban greenery or as a raw material for construction materials. This approach combines public health protection with efficient resource management. • Sweden – management of sediments in municipal services 🇸🇪 A comprehensive approach combining technical, regulatory, and social aspects, with an emphasis on long-term environmental and economic benefits. The project shows how to integrate circular solutions into local policies and practices.
Why it matters and what the goal is All pilot projects pursue one goal: reducing waste, extending the lifecycle of resources, and creating practical, replicable models. International expert feedback helps refine solutions so that they are safe, cost-effective, and socially acceptable. Thanks to this, small towns and rural areas receive real tools for circular transformation that can be implemented with limited budgets. 🛠️📈

Circular MuSe in Wejherowo: European partners are working together to develop practical circular economy solutions for cities and municipalities
This week, Wejherowo hosted an international exchange of experiences on the circular economy in municipal services. As part of a meeting of all Circular MuSe project partners, representatives of local governments, universities, and organizations from Poland, Denmark, Lithuania, and Sweden are working on concrete solutions designed to support more sustainable resource management in smaller cities and rural areas.
The two-day meeting is taking place at Ekofabryka Wejherowo and focuses primarily on practical activities: implementing pilot projects, exchanging knowledge, and preparing the next stages of international cooperation. Project partners discuss both the results of their activities to date and the next steps related to education, mentoring, and the development of tools to support local governments in the circular transition.
The first day of the meeting was primarily devoted to summarizing the project’s progress and experiences related to the implementation of training and educational activities. Partners present the results of the implemented training programs, the participant recruitment process, the most important topics raised by participants, and the practical aspects of organizing educational activities. Discussions also cover the further development of training modules in Poland, Denmark, and Sweden, as well as ways to engage local government representatives and businesses in the circular transition process.
Another key element of the meeting is discussions on mentoring and the development of the Circular MuSe Knowledge Hub—a platform for exchanging knowledge and best practices among project partners and stakeholders from various countries. Participants analyze the platform’s functionalities, its structure, and opportunities for further development so that it can more effectively support cities and municipalities implementing circular economy solutions.
One of the highlights of the program is a series of sessions dedicated to the pilot solutions being implemented by the project partners. These meetings take the form of an international expert review, during which the partners present the current status of their projects, technical specifications, and future investment plans. They then receive detailed feedback from the other participants and experts involved in the project.
In Wejherowo, one of the projects on display focuses on reusing sand left over from winter street cleaning. Partners from Denmark are presenting solutions for reusing sludge from water treatment plants, while Kalmar is showcasing initiatives for sludge management in the context of local municipal services. All these initiatives share a common goal: reducing waste, extending the life cycle of resources, and creating practical models that can be implemented in other cities and municipalities.
The second day of the meeting focuses on further developing the Circular MuSe knowledge base and building a portfolio of best practices for small towns and rural areas. Partners present the identified case studies and jointly assess their implementation potential, usefulness, and replicability in other municipalities. Particular attention is given to solutions that demonstrate how to effectively combine municipal services with the principles of the circular economy.
The meeting in Wejherowo is not only part of the project schedule but, above all, a space for practical cooperation among partners from different countries. Joint workshops, expert sessions, and study visits allow for the development of solutions that have a real impact on the development of more sustainable municipal services in Europe.
The program also included visits to the Eco-Factory and the urban areas of Wejherowo, allowing project partners to better understand local solutions and initiatives implemented by the local government and municipal entities responsible for municipal services.
The Circular MuSe project demonstrates that an effective transition toward a circular economy requires not only technology and investment, but also cooperation, the exchange of experiences, and the building of shared knowledge among cities, universities, and organizations from various European countries.

Circular MUSE Study Visit to Chlewnica
Today, representatives of the CircularMuse consortium had the pleasure of visiting ELWOZ Eco—the Waste Management Facility in Chlewnica—where they gathered inspiration for the creation of the Circular Municipal Service HUB. It was an extremely valuable visit, demonstrating how circular economy solutions are implemented in practice at the local level. We were particularly interested in examples of activities such as:
the production of soil amendment,
the recovery of construction debris used for road subgrade,
the production of alternative fuel (RDF) supplied to cement plants,
and many other innovative solutions supporting sustainable waste management.
Such visits are a valuable source of knowledge and inspiration for us in building modern, circular municipal services.
