This interdisciplinary research project explores the transformation of discarded cellulose-based waste into functional, sustainable sound-absorbing panels. Focusing on cellulose (C₆H₁₀O₅)—a biodegradable, renewable, and highly recyclable polymer—the study investigates how commonly discarded materials can be repurposed through biomaterial and chemical processing methods.

​

After extensive exploration, we developed a composite using waste from bakeries, such as eggshells and cardboard, combined with natural cellulose fibers. These materials were selected for their structural and acoustic potential, supporting circular economy principles.

​

Through experimental prototyping and sound absorption testing, the project demonstrated the viability of cellulose-based composites as eco-friendly alternatives to conventional soundproofing. Conducted in collaboration with Aalto University’s School of Chemical Engineering and School of Arts, Design, and Architecture, the research integrates our research outcomes, highlighting the potential of waste valorization

in sustainable material innovation.
