Abstract The global issue of PET bottles lies in their contribution to plastic pollution, as millions are discarded daily, often ending up landfills or oceans. This non-biodegradable waste poses a significant threat wildlife and ecosystems, while also contributing the growing crisis. study investigates acoustic performance panels made laboratory from recycled polyester fibre extracted post-consumer bottles, addressing environmental challenges waste. key objective this research is evaluate sound absorption properties these explore potential for application noise control solutions. was tested across range frequencies. Testing followed standard procedures determining characteristics accordance with ISO 10534-2 using impedance tube method. Results indicate that panel exhibit absorption, particularly mid-frequency an coefficient peaking at 0.95 4000 Hz, making them suitable use spaces such offices, classrooms, auditoriums. However, low-frequency remains limited, near zero frequencies below 80 Hz. In addition properties, offer benefits by reducing minimizing reliance on non-renewable resources commonly used treatments. highlights fiber effective sustainable solution various architectural applications. Further studies recommended long-term durability under different conditions, well cost-effectiveness compared conventional materials.
