Application of industrial waste for developing energy- efficient false ceiling panels

The unchecked increase of industrial solid waste, particularly in developing nations, has become a significant environmental issue. In response to this, recent energy regulations have emphasized the need for improved thermal protection in buildings, ensuring optimal energy efficiency, and adequate thermal comfort with minimal operating expenses. In this context, the repurposing of industrial waste for the development of sustainable construction materials presents a promising solution. This study investigates the production of lightweight, porous false ceiling panels with enhanced thermal properties, utilizing recycled paper mill waste (RPMW) and cement. The RPMW was thoroughly investigated using X-ray fluorescence (XRF), thermogravimetric-differential thermal analysis (TG-DTA), X-ray diffraction (XRD), and scanning electron microscopy (SEM). The TG-DTA analysis demonstrated that RPMW retains thermal stability up to 280°C, while SEM imaging revealed its fibrous structure and the presence of pores. By converting RPMW, typically disposed of in landfills, into functional construction materials, this approach not only addresses solid waste management but also provides opportunities for revenue generation and carbon credit accumulation. The resulting false ceiling panels, made from industrial waste, exhibit superior thermal efficiency while remaining cost-effective and lightweight. Additionally, the straightforward manufacturing process offers potential for rural entrepreneurship, creating employment opportunities for unskilled labor in developing regions.
