Multilayer packaging, extensively used in the food, beverage, and cosmetics industries, offers excellent protection durability by combining materials such as paper, plastic, aluminum. However, its complex structure creates significant challenges recycling, particularly separating layers. This review, conducted through a scoping analysis of peer-reviewed literature obtained from databases Google Scholar, PubMed, ResearchGate, reviews limitations current recycling technologies, including mechanical, chemical, solvent-based, enzymatic methods highlights experimental potential microbial degradation future solution. It also explores innovative approaches, upcycling, biodegradable alternatives, split-layer which reduce adhesive use simplify recycling. Legislative frameworks policy incentives are analyzed to underscore their role driving technological advancements fostering industry collaboration. Findings emphasize absence fully viable solution with regard for multilayer packaging under existing economic constraints. Although “Design-for-Recycling” emerging offer promising long-term strategies, temporary measures advanced incineration or regulated landfilling may still be required. Moving forward, innovation supported robust policies collaborative efforts, is essential align global sustainability goals contribute development circular economy.

The linear “take–make–dispose” model of plastic consumption has led to significant environmental challenges and unplanned waste legacies, emphasising the need for more sustainable recycling practices. This study explored integration post-consumer recycled polylactic acid (rPLA) into 3D printing filaments as a step towards manufacturing. Using 100% virgin PLA (vPLA) baseline, were produced with rPLA-to-vPLA ratios 0%, 25%, 50%, 75%, evaluated surface roughness, tensile strength, flexural properties, hardness. results revealed that increasing rPLA content negatively affects mechanical properties quality. Surface roughness increased from 7.06 µm pure vPLA 10.50 rPLA, whilst strengths decreased by 48.4% 49%, respectively, compared vPLA. Hardness also declined, showing 7.5% reduction relative Despite these reductions, blends up 50% retained over 90% performance vPLA, demonstrating viable compromise between sustainability. Morphological analysis highlighted poor interlayer adhesion void formation primary causes degradation in higher blends. challenges, this demonstrated rPLA-vPLA can extend life cycle promote manufacturing By addressing polymer research supports materials printing, contributing circular economy goals recycling, resource efficiency, production outcomes.

The world is facing the issue of managing a huge amount plastic waste. To prevent uncontrolled and unproductive disposal, various valorization strategies have been developed. Recycling waste into valuable composites for construction offers promising pathway toward sustainable management. Given that industry major consumer energy natural resources, it presents key opportunity integrating recycled materials. This review examines diverse applications recycling, with particular focus on solutions, while also evaluating advantages limitations this approach. Within context, can be used as filler to replace non-renewable resources. Studies shown incorporating improves properties composites, including thermal sound insulation. In particular, thermoset exhibits desirable characteristics such rigidity, heat chemical resistance, strength durability, making suitable non-structural applications. Alternatively, melting produce binder materials combine other inorganic form building composites. Using melted thermoplastic enhances ductility, reduces water absorption, overall durability. Additionally, hot-pressing technique has more effective in addressing poor bonding issues commonly encountered conventional methods.
