The BIOREGIO project aims at improving regional policies through increased focus on circular economy of biological streams. These streams comprise food waste/bio waste, municipal and industrial sludge and agricultural residues, which can be treated with similar technologies. BIOREGIO will improve knowledge related to policies and technologies of biological streams and increase the low recycling rates of these materials. In the project, the expertise of best available technologies, e.g. bio refinery, biogas production, and relevant operation models, e.g. ecosystems, networks and administrative cooperation, will be transferred. Interregional cooperation will enhance the understanding among staff members in authorities and participating organisations to better comprehend the possibilities for closing the loops of biological streams, e.g. as is fertilizers and biofuels, instead of disposal. BIOREGIO brings together 8 partners from 6 regions with expertise and desire to change the policies and boost the regional bio economy according to objectives of the EU Circular Economy Package. The project will also deepen and develop regional cooperation as well as raise public awareness. Project activities comprise joint development of policies as well as describing regional biological streams and defining best available practices. Regional and interregional cooperation will be tightly wrapped together for achieving the best benefits for regional policy development. BIOREGIO will organize well prepared round-table discussions, workshops, seminars and site visits. As a result of BIOREGIO the partner regions will be better equipped to develop new policies and implement new technologies and models in order to move towards circular economy of biological streams. In the long run this will enhance innovations related to saving natural resources as well as green growth and new jobs. The best practices of project innovations will be clearly documented and shared for wider EU use.
