AB  - The main goal of this work was to develop and test advanced techniques for the 
      instant identification of different type of polymers in post-consumer plastics. 
      In order to accomplish this task, infrared (IR), X-ray diffraction (XRD), 
      differential scanning calorimetric (DSC) and laser induced breakdown 
      spectroscopic (LIBS) techniques were applied. The following six model plastics 
      were identified in this study. Low-density polyethylene (LDPE), High-density 
      polyethylene (HDPE), Polypropylenes (PP), Polystyrene (PS), Polyethylene 
      terephthalate (PET) and Polyvinyl chloride (PVC) along with few randomly selected 
      plastics waste such as water bottle and cap, water cups, yogurt container and 
      coke bottle were studied. IR has shown the fingerprinting of polymer types 
      present in plastics waste. The XRD analysis helps to provide characteristic 
      spectral lines whose intensities vary with the type of each constituent polymer. 
      The DSC method provided the different crystalline melting temperature, glass 
      transition, and onset temperature for the peaks and the percent crystallinity 
      data single out different polymers. The ratio of LIBS signals intensities of 
      carbon and hydrogen atoms were employed for the finger printing of the different 
      family of plastics. The combined use of IR, XRD, DSC and LIBS techniques yielded 
      very useful and effective results for plastic waste management.
