Sorting / Collection
Wasted plastics are collected and sorted by type using a variety of methods, including wind, electrostatic, and optical sorting, and together, contaminants are removed.
In these processes, it is necessary to determine the type of resin and contaminants. For this analysis, a Fourier transform infrared (FTIR) spectrophotometer, energy dispersive X-ray fluorescence (EDXRF) analyzer, and differential scanning calorimeter (DSC) are useful.
