Blending Recycled Plastic from Bottle Caps with Banana Rachis Fiber for Waste Valorization

Abstract

The European Union's commitment to reducing waste generation has prompted significant transforrnations, particu larly focusing on enhancing recycling rates and minimizing landfilling [1, 2]. However, regions with constrained waste treatment infrastructure, such as the Outermost Regions (ORs) and islands, tace unique challenges iin meeting these directives [3]. This work explores the specific case of the Canary lslands, which currently struggles with low recycling rates and high landfilling percentages. In light of the EU's waste directives and the pressing need for sustainable waste management solutions, this study invesfilgates the feasibility of implementing Circular Economy principies within the polymer transforrnation industry ofthe Canary lslands. The research focuses on utilizing a polymer blend derived from recycled plastic bottle caps, coupled with banana fibers extracted from banana plants' pseudo-stem and rachis. Results indicate that the polymer blend, reinfarced with banana fibers, exhibits promising mechanical properties and cost-effectiveness, positioning it as a viable altemative to traditional plastic materials. Composite materials with higher reinforcement percentages demonstrate superior mechanical performance, suggesting their potential far various applications. Furtherrnore, this study emphasizes the importance of extracting value from urban and agrofarestry waste streams, thereby reducing environmental impacts associated with waste disposal. By adopting Circular Economy strategies, regions like the Canary lslands can not only address their waste management challenges but also contribute to broader sustainability goals. This research underscores the significance of innovative approaches to waste management, particularly in regions facing inherent limitations. By leveraging local resources and embracing Circular Economy principies, the Canary lslands and similar regions can pave the way far a more sustainable and resilient future.
