Currently, a large amount of food is thrown away each year in the BSR. Closing the biowaste loop remains a challenge but also holds untapped economic potential for local actors in the region. FoodLoops tackles this challenge in two ways. First, the project empowers municipalities, educators and caterers to improve better biowaste separation at source (e.g. in school kitchens and canteens and in households). Second, it guides these actors in cooperating to develop solutions that turn unavoidable (food) waste into products of value, such as organic compost, as well as engage potential markets for these products, such as local organic farmers. Turning what is commonly perceived as waste in this way into something of value that can be reused helps to close the resource loop by reducing the amount of waste as well as reducing the amount of new material that would otherwise need to be introduced into the production cycle. With project activities focused mainly in Poland, Lithuania and Finland, FoodLoops focuses on building trust between local stakeholders as a basis for cooperation. In a series of workshops, local and regional farmers associations, municipalities, caterers, and school administrators and educators work with each other to co-create solutions for biowaste valorisation. FoodLoops draws on good practices in the BSR and Europe and aims to foster replication of cooperation models developed in the project through transnational training workshops.
