The Challenge of Plastic Sorting Plastic recycling presents unique challenges due to the diverse range of plastics in use. Different types of plastics—such as PET, HDPE, PVC, and more—often come in various colors, making manual sorting a daunting and inefficient task. Traditional methods relied on human labor to identify and separate plastics based on type and color, a process that was not only time-consuming but also prone to errors and inconsistencies. The Role of Plastic Color Sorters Plastic color sorters utilize advanced optical and sensor technologies to automatically detect and sort plastics based on their color. These machines are equipped with high-resolution cameras, sensors, and sophisticated software that analyze the color and type of each plastic item as it passes through the sorter. The sorter then uses air jets or mechanical arms to separate the plastics into different categories.
