The project BALTIPLAST aims at prevention and reduction of plastic waste in the Baltic Sea Region, focusing on single use plastic reduction, improvements in plastic packaging and innovative collection and treatment systems at the municipality level. A consortium of partners from Germany, Sweden, Finland, Estonia, Latvia and Lithuania, will test concrete solutions at three levels of operation: Strategic and management; technological/technical; communication/behavior change. The project involves some key actors in the plastic waste value chain, primarily municipalities in the participating countries, as well as SMEs and large enterprises operating in the field of waste management. NGOs and interest groups will be involved, for the dissemination of results. It contributes to EU Strategy for the BSR, specifically to the Policy Area of Bio-economy, dwelling on responsible use of resources, changing mind-sets and consumer behavior, through cross-sectorial approaches, by up-scaling waste to integrate it to a circular economy, by testing public procurement models and integrating circular economy policies in the activities of the target groups. The project design is guided by co-creative innovation, through new schemes of collaboration in country clusters, as reflected in the Group of Activities, further transferring them to a transnational level. Ultimately, BALTIPLAST may provide a long term contribution to on-going efforts to reduce the plastic that enters the Baltic Sea Region.
