Recycling Multilayer Materials: Discovering Mechanical Parameters for Engineering Applications

Abstract

Multilayer materials have been widely used in various applications such as packaging, electronics, and construction industries. However, the disposal of these materials is becoming a significant environmental concern due to their non-biodegradable nature. Therefore, the recycling of multilayer materials has become an essential aspect of sustainable waste management. The mechanical characteristics of materials recycled from multilayer products were examined in this study. The focus was on determining the impact of recycling on the mechanical properties of the materials. We collected samples of multilayer materials and separated them into individual layers. The layers were then cleaned, processed, and reassembled into new multilayer materials. Testing was done on the new multilayer materials to determine their tensile strength, impact resistance, and elasticity. The results of the study indicated that the mechanical properties of recycled multilayer materials were influenced by various factors, such as the number of layers, processing conditions, and composition of the original material. To prevent their burning, placement in landfills, or reuse of their constituent parts, multilayer food packaging can be recycled. The material is made by joining numerous sheets together using temperature and pressure that are not applied simultaneously. The sheets are joined by the fusion of polyethylene and take place without the need of any other adhesives. Temperature, pressure, time, and the quantity of sheets are chosen as the factors, and their effects on the mechanical characteristics are calculated.
