Development of a Composite Board for Ceiling Tiles from Sawdust, Waste Paper and Recycled Polyethylene Terephthalate

The construction industry is currently dealing with the task of finding consistent building materials. This study presents an advancement in construction materials through the development of a composite board tailored for ceiling applications. The board is engineered using waste materials by the coating method, in which sawdust and waste paper mixed with epoxy are sandwiched between two layers of recycled polyethylene terephthalate. It exhibited better properties, including a flexural strength of 4.42 MPa, minimal water absorption of 1%, low thermal conductivity, and a lightweight profile. Through a comprehensive comparative analysis of numerous composite boards studied before, the composite board emerges as the better choice across a spectrum of performance metrics. Leveraging waste materials in its formulation aligns with the principles of resource sustainability and a circular economy. The composite board's performance offered a promising solution to address environmental demands in contemporary construction practices. This highlighted the potential for waste materials to redefine the industry's landscape.
