“Addressing the Plastic Waste Challenge: The Vital Role of Analytical Chemistry and Spectroscopy – A Chemical Engineer’s Perspective”
The worldwide production and consumption of synthetic polymers have increased steadily over the last few decades with an estimated 380 million metric tons (MMT) in 2015 compared to 2 MMT in 1950 [1]. The generation of plastic waste is increasing at an alarming rate due to the extensive usage of plastics. Plastics are one of the major contributors to the waste management problem on land and in oceans. It is thus imperative to improve ways to efficiently recycle the post-consumer plastics. Currently only 10% of waste plastic generated world-wide is being recycled. To achieve sustainability and promote circularity of plastics, it becomes imperative to recycle the post-consumer plastics. Pyrolysis being a promising chemical recycling technology is in the forefront to recycle mixed plastic waste streams due to its economic viability and robustness.
The separation of pyrolysis products is typically carried out using one-dimensional gas chromatography (1D-GC) coupled to different detectors such as mass spectrometry, flame ionization detector, etc. Nevertheless, 1D-GC does not necessarily provide accurate and comprehensive information related to all the pyrolysis compounds due to relatively lower resolution and overlapping peaks. Alternately, two-dimensional gas chromatography (GC×GC) enables higher resolution of products using selected two different packing types and minimizes coelution of compounds. The GC×GC method development is essential to obtain accurate characterization data for analyzing pyrolyzates produced during the pyrolysis of polymers and hence to develop efficient and reliable recycling and upcycling strategies for valorization of plastic waste.
In this talk, I will show how GC×GC coupled to time-of-flight mass spectrometer detector (TOF-MS) and flame ionization detector (FID) can provide detailed characterization of pyrolysis oil composition, to identify possible contaminants and help to refine process design.
