The JOINABLE project represents a collective effort of nine partners from six countries (Italy, Croatia, Montenegro, North Macedonia, Albania, and Greece), aimed at enhancing the development of acircular blue economy that is based on plastic waste collected from aquatic environments. This proje ctaims to examine the current situation regarding plastic waste, including the regulatory frameworks, in each participating country. It will involve educating trainers on the use of digital tools and spectrometers, developing a methodology for cleaning and monitoring plastic waste, and creating a system that transforms plastic waste into new products. Additionally, the project will share knowledge with local and regional authorities and feed databases like EMODnet. Ultimately, the goal is to develop a comprehensive strategy for managing plastic waste in the ADRION region by fostering the development of the blue circular economy. This strategy will address the specific challenges and opportunities within the region, aiming to reduce the environmental impact of plastic waste while promoting sustainable economic growth through innovative recycling and waste management practices.
