The potential of light guidance panels (LGPs) in the field of recycling technology has not explored to meet its full efficiency in the recovering of polymeric component from it. As consequences such components are either incinerated or used for land filling purposes. Therefore, this work aims to address the recycling and reutilization of poly(methyl methacrylate) (PMMA) recovered from light guidance panels used in the liquid crystal displays (LCDs). Fourier transform infrared (FTIR) analysis, resin identification code (RIC) and density methods confirm the presence of PMMA as the major polymer used in LGPs. Additionally, energy dispersive spectroscopy (EDAX) analysis reveals the absence of heavy metals and flame retardants in collected PMMA. Furthermore, mechanical, thermal and morphological characteristics of recovered PMMA were compared with its corresponding virgin material, which confirms the further recyclability of recovered PMMA from LGPs.
