On this lecture, Francisco Siena Vieira, VTT's Research Scientist, will be sharing insights about existing main plastic waste streams.
Francisco Siena Vieira, from VTT explains deeply the use of a sensor-based plastic for identification and sorting applying spectroscopy principles.
In the last part of this section, Francisco Siena Viera from VTT show some examples of the application of the sensor-based plastic identification using near-infrared spectroscopy technology. Francisco also shows the existing commercial solutions, challenges and the VTT active hyperspectral sensor.
Professor Janne Jännis, renowned for his expertise at the Department of Chemistry of University of Eastern Finland, delivered a lesson on high-resolution mass spectrometry characterization of plastics. This lecture covers the distinction between polymers and plastics, physical and chemical properties of polymers, and the chemistry of plastics.
Janne Jännis from the University of Eastern Finland, focuses on the mass spectronometry characterization of plastics. The present lecture explains:
The use of mass spectrometry in analyzing polymers and plastics with techniques like electrospray ionization and matrix-assisted laser desorption/ionization.
The importance of high mass resolution in analyzing complex plastic samples and identifying polymer characteristics.
The role of mass spectrometry in identifying polymer identity, heterogeneity, branching, molecular weight, and end-group chemistry.
The significance of flame retardants in plastics and common classes of brominated flame retardants used.
