Abstract

Cold storage systems are critical for maintaining the quality and safety of temperature-sensitive products in industries such as food and pharmaceuticals. The performance of these systems heavily relies on efficient thermal insulation materials that minimize energy consumption while ensuring product quality. However, traditional insulation materials often face challenges related to high production costs, environmental impacts, and inconsistent performance under varying conditions. This study explores the potential of using sugarcane bagasse, an agricultural byproduct, to enhance the thermal properties of polyurethane-based composites for use in cold storage insulation. Polyurethane’s low thermal conductivity and versatility make it an ideal candidate for insulation, but its environmental impact and cost constraints have driven interest in sustainable alternatives. Bagasse fibers, abundant and renewable, are incorporated into the polyurethane matrix to evaluate their effect on thermal conductivity. The results indicate that increasing the fiber content from 0% to 60% consistently reduces the thermal conductivity of the composites, with a final value of -11.7 W/mK at 60% fiber content. This reduction in thermal conductivity is attributed to the fibrous structure of bagasse, which disrupts heat flow and increases porosity. These findings suggest that integrating bagasse fibers into polyurethane composites can improve their thermal insulation properties while promoting sustainability. The study highlights the potential of bagasse as a valuable material for developing eco-friendly and cost-effective insulation solutions.
