This thesis focuses on the construction of an innovative recycling centre for 3D printing of plastics on the island of Syros, in the Aegean Sea. The primary objective of the centre is to reduce and then eliminate plastic pollution in the region. The issue is addressed by collecting plastic waste from nearby areas and from the local landfill, and converting it, using 3D printing technology, into products necessary for humans, thereby promoting a circular economy.

 By using 3D printing as a means of production, the project seeks to minimise resource consumption and reduce the carbon footprint associated with traditional production methods. The resulting structures serve as tangible evidence of the transformative potential of plastic waste, highlighting the value and practicality of recycling to create sustainable and aesthetically appealing products.

 The Aegean Sea, known for its ecological diversity and economic importance, has been affected by plastic pollution to the extent that marine life is endangered and the overall health of the ecosystem is compromised. At the same time, the local landfill site of Syros presents its own environmental challenges. This paper acknowledges these concerns and seeks to address them holistically, providing a comprehensive solution that addresses both issues.

 Through an extensive interdisciplinary approach, the paper aims to explore the technical, economic and environmental aspects of the establishment and proper operation of the plastics recycling and 3D printing plant. It includes research on optimal recycling techniques, 3D printing, waste collection strategies, the development of partnerships with local and non-local stakeholders and an assessment of the wider implications of the project in terms of sustainability and waste management in the region.

 In conclusion, the thesis seeks to contribute to the ongoing fight against plastic pollution in the Aegean Sea, while addressing the challenges associated with local waste management. By advancing the circular economy model and emphasizing the transformative role of recycling, it seeks to inspire sustainable practices, raise awareness and foster positive change in the local community and beyond.
