Biobased side and waste streams

Creating circular economy markets, business models and biobased value chains while boosting the urban-rural symbiosis

The future circular bioeconomy must be based on the efficient use of raw materials that also supports the use of local resources. Working closely with farmers, other industries, municipalities, and regions, TREASoURcE will create circular bioeconomy markets and business models, support the formation of biobased value chains and explore the possibilities of using urban and rural waste and side streams.

TREASoURcE will demonstrate the efficient formation of local value chains that use local resources for biogas and recycled fertilizers, rather than leaving them unused. This will include large-scale mapping of raw materials and optimization of logistics. The optimized side and waste stream value chains will be supported by a developed digital marketplace, which will also be replicated to other project countries.

Promoting market development for bio-streams through a digital marketplace

The TREASoURcE project has developed and launched a digital marketplace for biobased by-products and waste streams, KiertoaSuomesta.fi (CircularFinland.fi). The marketplace helps the sellers and the buyers of materials to find each other. The main target groups are companies that produce biobased side streams from agriculture, forestry and food processing, as well as industries that use raw materials and the public sector.

The platform can also be used to list contracting services and for feed trade. The aim of KiertoaSuomesta.fi is to create new business opportunities for primary producers in a convenient way. Farms will be able to generate additional income by selling side streams and industrial operators will be provided with new raw materials.

The project cooperates with actors in the circular bioeconomy and collects new opportunities for the sector. Active communication about the possibilities of the sector will be carried out to share knowledge about the opportunities.

Powering local economies through circular bioeconomy

Pirkanmaa, Tampere region in Finland, is the main pilot area, where collaboration with municipalities is taking place to promote the use of biobased side and waste streams. Active cooperation is also conducted in Østfold and Fredrikstad. The first replications for the business models will take place in Tallinn and Tarto in Estonia, after which replication will also be promoted in Northern Europe. Best practices will be collected in the project’s Replication Handbook.

The focus of the work with municipalities has been on biogas production and nutrient recycling. In addition to agricultural side streams, such as manure, straw and grass biomasses, also municipal biowaste and sewage sludge from wastewater treatment plants have also been considered as a part of the biobased system.

What is the Rural-Urban Symbiosis Tool?

Rural–urban symbiosis is a concept that emphasizes the mutual interdependence between urban centers and their surrounding rural areas. At its core, it involves the exchange of resources, services, knowledge, and innovations in ways that generate shared value and support the development of more resilient, circular, and regionally integrated economies. This approach is grounded in the foundational work developed by MTK in the report Symbiosis between rural & urban areas originally published by MTK in 2020 and updated in 2024 to reflect new insights and developments, laying the basis for translating the concept into practical, scalable tools.

The Rural–Urban Symbiosis Tool was created to bring this concept to life. It builds on a refined symbiosis model and has evolved from a static conceptual framework into a dynamic, user-centered, and interactive experience. By being hosted on the widely adopted Moodle learning management system, the tool is accessible, flexible, and easy to use for a wide range of audiences.

The platform empowers stakeholders to better understand and apply circular economy strategies tailored to their specific regional contexts and it serves as a strategic guide that supports local and regional actors—such as municipalities, planners, businesses, and policy makers—in identifying and utilizing bio-based side and waste streams through innovative collaboration.
