The Evaluation of Thermal Insulation Performances of 100% Recycled Thermoplastic Composites

Considering the risks facing nature today, the search for sustainable materials has become a necessity. The polyethylene, which is the main waste of the packaging sector, and the cotton fibers, which are among the leading wastes of the textile industry, are increasing day by day and the recycling these wastes by using them as reinforcement materials in composites emerges as a sustainable solution. The main purpose of this study is to develop a thermal insulation panel by combining the wastes from two different sectors. Therefore, 100% recycled composite materials are designed according to the different numbers and sequences of recycled cotton fiber layers and recycled polyethylene matrix plates and produced by hot press method. The physical and thermal properties of the samples are tested to evaluate their usability as a sustainable insulation panel.
