A liquid crystal display (LCD) recycling process is needed to increase its efficiency by recovering the resources in addition to metals and plastics. This study investigates the pre-treatment process for recycling LCD glass. Recycling pre-treatment includes dismantling the LCD from the waste product, crushing the glass, and separating the glass particles from the impurities. Scanning electron microscopy confirmed that the oscillation milling process is more effective in maintaining uniform powder shape and size as compared to the cut milling process. The glass particles crushed by the oscillating mill, optimized at 1500 rpm, had a uniformly distributed particle size of less than 10 μm. These small particles were separated from the organic impurities, achieving a 98% pure powder that can be used as recycled raw materials. The proposed pre-treatment process for recycling LCD glass will enhance the ability to use waste glass as a valuable resource in the manufacturing of future displays.
