Researchers have developed a new hyperspectral Raman imaging lidar system that can remotely detect and identify various types of plastics. This technology could help address the critical issue of ...

The prototype hyperspectral Raman imaging lidar system included a pulsed 532- nm green laser and a 2D imaging spectrometer with a gated ICCD. WASHINGTON — Researchers have developed a new ...

For the first time, we can now tell the difference between a wide range of plastic types and thereby separate plastics according to their chemical composition. This is absolutely ground-breaking and ...

Plastic litter has emerged as a pollutant of concern in the oceans around the world over the past few decades. Defined as plastic litter that is smaller than 5 mm, microplastic is thought to be the ...

Properly identifying plastic by resin type is a key to profitability for brokers, recyclers and reprocessors of plastic scrap. Some brokers and recyclers can find that misidentified loads of plastic ...

In this video, we explore methods for identifying different types of plastic, focusing on elastomers, thermosetting plastics, and thermoplastics, along with the Resin ID codes (recycling symbols) when ...
