Cellulose Paper Composition as a Key Factor in Eco‐Friendly Green Roof Tile Performance

Abstract This study explores the role of cellulose paper composition—comprising holocellulose, hemicellulose, cellulose, and lignin—on the physical and chemical properties of eco‐friendly green roof tiles. The investigation focuses on key performance metrics including hardness, water absorption, flammability, thermal stability, and overall composition. By incorporating recycled cellulose paper, these tiles not only contribute to reducing environmental waste but also support a circular economy in the construction industry. The results demonstrate that these eco‐friendly tiles exhibit a significant increase in hardness (20 HCR units higher than commercial tiles), a reduced water absorption rate of approximately 13%, and good ignition resistance up to 284 °C, enhancing their durability and fire safety. Advanced analytical techniques, including Scanning Electron Microscopy (SEM) and Fourier Transform Infrared Spectroscopy (FTIR), confirm the effective integration of cellulose fibers within the tile matrix, leading to a homogeneous chemical distribution. Statistical analysis further validates that these sustainable tiles outperform conventional materials in key performance areas. The findings emphasize the transformative potential of cellulose paper composition in creating sustainable, high‐performance roofing materials.
