Our optical (NIR) separator is a sophisticated sorting system that separates materials based on their molecular properties. It features a system that analyzes reflected NIR (near-infrared) light from the surface of materials and classifies them for high efficiency sorting.
This capability is made possible by near-infrared (NIR) light, a type of electromagnetic wave with wavelengths ranging from 780 to 2526 nm.
Biological materials typically contain numerous hydrogen-containing groups, such as -OH, -CH, -NH, and -SH. When exposed to near-infrared light, these chemical groups vibrate and absorb energy.
NIR technology captures the physical and chemical properties of these vibrations, which, combined with chemical quantitative analysis, enables precise qualitative and quantitative assessment of biological samples.
The optical sorting system is suitable for the sorting of a wide range of materials such as wood, plastic, paper, cardboard, as well as ferrous and non-ferrous metals.
These optical sorting systems can be integrated with MRF, MBT, RDF, and PET automatic sorting lines to effectively and efficiently sort waste by material or color. This technology is playing a vital role in waste recycling and fuel generation operations.
You might be wondering what to do in case you are sorting waste composed of multiple materials but this system has you covered. For example, by simply adjusting the computer program, you can have the system identify PET materials without identifying PE caps or PP labels of PET bottles.
