Multifunctional performance assessment of waste-based bioplastic wall panels for acoustic thermal and structural efficiency in interior architecture

The study presents a comprehensive evaluation of bioplastic wall cladding units fabricated from organic and plant-based wastes, focusing on their acoustic, mechanical, and thermal performance. The research investigates various configurations, including solid, hollow, and carpet waste-covered tiles, to assess their multifunctional properties. Acoustic testing revealed that carpet waste-covered tiles provide superior sound insulation, achieving performance levels comparable to laminated gypsum boards. Mechanical testing demonstrated sufficient yield strength, flexural strength, and modulus of elasticity, confirming their suitability for non-load-bearing interior applications. Thermal testing highlighted effective insulation capabilities, with linen bark and orange peel configurations showing optimal performance. By integrating recycled materials such as carpet waste, this study addresses critical environmental challenges while enhancing the properties of bioplastic cladding. The findings underscore the potential of these tiles as eco-friendly alternatives to conventional materials, offering architects and designers innovative solutions for sustainable and functional interior design. Future research directions include evaluating long-term durability, fire resistance, and advanced formulations to expand the applications of bioplastic cladding in modern architecture.
